ESSAY I

FAITH AND REVEALED TRUTH

by Rev. George D. Smith

I.   INTRODUCTORY

“I so run, not as at an uncertainty; I so fight, not as one beating the air” (1 Cor. ix 26).  The Catholic, strong in faith, might well describe his attitude towards life in these confident words of St. Paul.  He is in no doubt as to his destiny, nor as to the manner in which he must achieve it.  God, his attributes, his providential designs in man’s regard, man’s own duties to his Creator and to his fellow men–all this, and much more, he knows with a certainty that is supreme.  These religious truths are the basis of his life; his appreciation of them determines the whole course of his existence; and if concerning them he had the slightest real doubt, his outlook would be radically changed.  He is certain that there is a God, his Creator and Lord, whose loving friendship he must at all costs retain; did he doubt it, his obedience to what he conceives as divine commands would falter.  He is certain that there awaits him a life after death in which, if he has been faithful, he will enjoy God’s eternal embrace; did he doubt it, his life on earth would be deprived of all meaning and purpose.

If, therefore, a man is to lead a religious life–and a religious life is synonymous with a good one–he must have firm and sound convictions concerning God and his duties in God’s regard.  He must have convictions, otherwise his life will be purposeless; they must be firm, else he will be inconsistent in practice as his theory is vacillating; they must be sound, for upon them depends the success or the failure of his life.  The Catholic has certainty on these vital matters because God has revealed them to him.  His hope rests upon the firm foundation of God’s word.  “Faith is the substance of things to be hoped for.”

But to judge the value of revealed truth merely by its use in action would be to estimate it incompletely.  Revelation extends the field of our knowledge, and this itself is a perfection of the mind, the noblest faculty of man.  By revelation we receive something of the inner radiance of God’s glory; by faith we learn divine truths of which humanly we should never have dreamed.  By faith we are given a foretaste of the wonders which will be fully disclosed only when we see God, no longer “through a glass in a dark manner,” but face to face.  In the meantime the radiance is too bright for our finite minds.  We adore, but we cannot see.  “Faith is the evidence of things that appear not.”

To display the riches contained in revelation is the object of the subsequent essays.  In this, the first, we must study the meaning of revelation itself, and the act of faith by which we accept it.

II.   RELIGION AND HUMAN REASON

1.  Validity of human reason

The Catholic theologian sets out with the supposition–which as a philosopher he is prepared to vindicate–that the human mind is able to know truth.  If anyone, therefore, in that unhappy state of mind which despairs of attaining certain knowledge upon any subject whatever, should hope to find in this essay a philosophical proof of the validity of mental processes, then he is doomed to disappointment.  The skeptic, before he can approach the study of theology, or in fact of any science at all, must first find his remedy in a sound and true epistemology.  Nor is it within the province of the theologian as such–although again as a philosopher he may be well equipped–to justify the first principles of analytical reasoning, to prove that the conclusions which issue from the application of those principles are valid, even though they may lead the mind into a realm of reality of which no actual experience is given, and thus cannot be verified by experiment.  The demonstration of these and kindred truths belongs to a branch of knowledge which is antecedent to the science of theology.

2.  Anti-intellectualism

I venture to hope, however, that those who read this series of essays have remained unaffected by the wave of skepticism and agnosticism which has swept over Europe during the last two or three centuries.  It is an interesting phenomenon of religious history that the heresy of Luther, taking its rise in a proud rebellion against the teaching authority of the Catholic Church, issued in a pessimistic theology which, exaggerating the effects of original sin, presented human nature as intrinsically corrupt.  The human will, bereft of freedom, was radically incapable of pursuing the good, the human reason was powerless to know the truth.  As man’s broken will must submit passively to the grace of God, so much his mind now, darkened by sin, allow itself to be led by an occult and irresistible force, a blind and unreasoning faith.  The agnosticism of Kant and his disciples, which, denying the validity of metaphysical argument, takes refuge, in order to justify religious belief, either in the dictates of the practical reason or in an unreasoning religious sense, is an essentially Protestant philosophy; and of this tendency to rely upon a blind instinct in religious matters the modern forms of exaggerated–and therefore false–mysticism, the systems of religious pragmatism and sentimentalism, so common outside the Church, are the more or less direct descendants.

From all such attempts to disparage the powers of the human reason the Catholic Church has remained ever aloof.  Some of her children, it is true, have not been immune from the anti-intellectualist atmosphere of their time; but they have been solemnly warned and, when occasion demanded, condemned by the ever-watchful guardian of Divine Truth.  Thus the Traditionalists of the nineteenth century, convinced by the German agnostics that the foundations of religious belief and practice, such as the existence of God, the freedom of the will, the immortality of the soul, could no longer be justified by an appeal to reason, had recourse to the inheritance of truth which the human race has received by tradition from antiquity, and ultimately from God.  The suggestion was well-intentioned and, like most errors, contained a considerable measure of truth.  The Traditionalists rendered valuable service by emphasizing the great part played by human authority in the acquisition of knowledge; it is true, moreover, that we receive much of our religious knowledge from divine revelation.  But these faint-hearted apologists, by denying to human reason the power to prove the existence of a God who reveals, rendered all faith in him unreasonable.  To save the ship they cast away the compass; and the Church was not slow to reject this ill-judged compromise with skepticism.

3.  Modernism

More recently certain restless spirits within the Church, anxious to reconcile Catholic doctrine with the so-called exigencies of “Modern Thought,” formed the school known as Modernism.  Rejecting with Kant all rational demonstration of religious tenets, and borrowing from his disciple Schleiermacher “the religious sense” as a criterion of truth, the Modernists found the source and the explanation of all religion in a subconscious “need of the divine.”  Thus the revelation which the Traditionalists (rightly) sought from God the Modernists (wrongly) thought to find within the nature of man himself.  From this the way lies open to pantheism, to the rejection of all dogmas, and indeed of all objective religious truth.  It would be beyond the scope of this short essay even to enumerate the manifold errors which Modernism involves; it was rightly stigmatized by Pope Pius X as “a compendium of all heresies” (I write of Modernism in the past tense, because for Catholics it is a thing of the past.  Nevertheless the tendency is still strong outside the Catholic Church.)

4.  Attitude of the Church

The teaching of the Catholic Church on this all-important subject is stated clearly by the Vatican Council(1869-1870): “Holy Mother Church holds and teaches that God, the beginning and end of all things, may be certainly known by the natural light of human reason by means of created things” (Const. de fide cath., chapter ii).  The terms of the oath against Modernism render impossible any misunderstanding of this definition.  By “created things” are meant, not merely human testimony, not merely a subconscious religious sense, but the “visible works of creation”; and lest there should be any doubt as to the manner in which our knowledge of God is acquired, the formula tells us that it is by applying the principle of causality to the data of experience: “God . . . can be known as a cause through his effects.”

The Church, in thus vindicating the power of human reason to know God, is but reaffirming what St. Paul had said in his Epistle to the Romans: “The invisible things of him, from the creation of the world, are clearly seen, being understood by the things that are made” (Rom. i 20; cf. Wisd. xiii 1-9).  But the power of the human mind is not limited to the mere knowledge of the existence of God.  Man is able unaided to know much concerning the nature of God; he can know many of his own duties in regard to his Creator, duties of worship, love and thanksgiving; he can learn naturally much concerning his own nature and destiny, his duties to himself and to his fellow men.  There is, in short, a whole body of religious truth–the truths of the natural order–which man is able to acquire with certainty by the normal use of his natural powers.

5.  Necessity of revelation

But while the Church is solicitous to vindicate the just rights of the human reason, while she has no sympathy with those who unduly disparage it, she strenuously resists the claim of Rationalism that it is “the sole judge of the true and the false . . . that it is a law to itself and sufficient by its natural powers to procure the good of men and peoples” (Syllabus of Pius IX, n. 3).  She asserts the essential soundness of the human mind an its radical capacity for learning all natural truth; but she is mindful that man is in a fallen state, that disordered passion and the manifold distractions of material things hamper and retard him in his pursuit of religious knowledge.  What I have called truths of the natural order can be known and demonstrated by the proper application of the principles of reasoning; but such a process requires a special type of mind, it needs leisure, concentration, an environment conducive to thought.  Experience shows that not all men have the ability to follow reasoning, be it of the most elementary kind; some men have a practical rather than a speculative bent.  Many who have the ability have not the leisure for these studies.  The practical difficulties become more evident when one considers that the rational proofs of such truths as the spirituality of the human soul, the freedom of the will, if they are to stand the test of modern objections, require as a preliminary a long and arduous study of metaphysics and psychology.  Add to this that religious knowledge is of paramount importance for man’s daily life, necessary especially in youth, when the character is in process of formation, necessary precisely at the time when, through mental immaturity and lack of concentration, he is least likely to be able to acquire it. 

Thus if we view mankind as a whole, if we consider the difficulties with which men are beset, it is clear that, left to their own resources, very few would gain adequate knowledge even of the truths of natural religion.  Nor does human authority offer an adequate solution of the difficulty.  History shows that the great thinkers of antiquity–not to speak of more recent or contemporary philosophers–have been unable to impose their doctrine beyond a certain school.  The clamor of diverse views, the difficulty of the subject-matter, the lack of authority in the teacher to impose belief upon those who cannot understand his reasoning–all this rendered, and still renders, merely human teaching authority powerless to supply the need of mankind for religious instruction.  On this subject above all man needs an omniscient and infallible Teacher.

Hence, even though the field of religious doctrine were confined to “natural” truth, man’s need of divine aid is apparent.  But it should be carefully noted that this need arises, not, as the Traditionalists contended, from the radical impotence of the human mind as such, but from other circumstances of human life which render it practically impossible for all men to discover these truths for themselves with any sufficient degree of accuracy and certainty.  Briefly, just as in the practical order grace is morally necessary in order that each man may observe all the precepts of the natural law, so is revelation necessary so that all men may reach a sufficient knowledge of the truths of natural religion (Cf. Essay xvii: Actual Grace).  The exaggerated claim of Rationalism is thus seen to be unreasonable.

But here again, in a most important particular, the Church opposes the Rationalist.  According to the latter, not only can the human mind unaided know all natural truth, but natural truth is all that there is to know.  The Church, on the contrary, teaches that there is an order of reality above that of nature, an order of reality which is beyond the reach of the human mind: the supernatural order.

And that such an order exists does not seem a priori unlikely.  God, as St. Paul tells us, has left traces of himself in his handiwork, and man is able from the consideration of created perfections to learn much concerning his Creator.  Even the little that we naturally know of God would lead us to conjecture that there is much more of which we know nothing; that there are divine perfections of which no clear trace appears in the works of creation; that besides the natural truths of religion there may be hidden truths concerning God and things divine, “mysteries –i.e., truths which must remain God’s secret unless and until he vouchsafes to make them known.

The supernatural order, therefore, by its very character is outside the scope of our natural knowledge and comprehension.  We can know nothing of it unless God wills to reveal it.  The impotence of human reason in respect of supernatural truths is physical and absolute.  Natural truth is within the reach of the human mind.  The reasons which show an adequate and universal knowledge of this order to be morally impossible without revelation are concerned not with the powers of the human mind itself, but with such concomitant circumstances as lack of ability, or time, or concentration.  But no course of study, however long, however arduous, could bring the human–or indeed the angelic–mind to the discovery of a supernatural truth.  This calls for a special intervention of God, for the inauguration of a divine intercourse with man whereby he communicates knowledge otherwise unattainable; in other words a supernatural revelation.

Man’s need of revelation is therefore twofold.  He needs it for ease and security even in the sphere of natural research; he needs it absolutely if he is to know God’s secrets.  The first need God might have supplied by help of the natural order, by an enlightenment or an inspiration which would have been included in God’s natural Providence in man’s regard.  God, however, has willed to destine man for a supernatural end, and every help that he grants is bestowed with that end in view.  Man’s twofold need is met by one divine revelation which is supernatural in character, and in its content partly supernatural and partly natural.  By one and the same revelation he supplies a remedy to man’s natural weakness, and discloses truths which no finite mind could ever have learned.

III.   SUPERNATURAL REVELATION

1.  Meaning of revelation

It is important for a proper understanding of our subject to have a clear idea of what is meant by divine revelation.  The word “revelation” is used in many senses.  In common parlance it often means the disclosure of a fact hitherto unknown: “What you say is a revelation to me”; and in theology the word sometimes has this meaning.  Or, again, it is said that God has “revealed” himself in the works of creation; and in this sense the Psalmist signs that “the heavens tell forth the glory of God.”  Moreover, God may manifest some truth to man by an interior enlightenment of his mind in such a way that the favored soul is unaware of the origin of his knowledge; he simply begins to know what he did not know before.  Of such a kind was the infused knowledge granted to many of the saints.  Such a mysterious illumination also may be called a revelation.  The Modernists used the word in a special sense.  By revelation they meant the manifestation of a religious truth made in consciousness by the religious sense; for them it was nothing else than a personal religious experience.

But when the Church uses the word “revelation” in connection with faith, it has the definite meaning of a divine testimony.  Revelation is the act whereby God speaks to man, making a statement to the truth of which he testifies.  “God who at sundry times and in divers manners spoke in times past by the prophets, last of all in these days hath spoken to us by his Son” (Heb. i 1).  Hence the Vatican Council(1869-1870) describes faith as a “virtue whereby . . . we believe that the things which he has revealed are true . . . because of the authority of God himself who reveals them, and who can neither be deceived nor deceive.”  The oath against Modernism, to exclude the perverted sense given to the word in that theory, uses even clearer terms.  Faith is there defined as “a true intellectual assent given to a truth received by hearing from without, whereby . . . we believe to be true the things that have been said, testified and revealed by a personal God, our Creator and Lord.”

Revelation, then, is not an interior emotional experience; it is a statement of truth made to man in a definite place, at a definite time, by a personal God who is outside and distinct from the recipient.  Moreover it is essential to the concept of revelation as understood by the Church that the statement in question be authenticated: the statement is received by the believer as made by God, and accepted because it is made by God.  Infused knowledge, therefore, unless it is infused with clear notification of its divine origin, is not the revelation which faith presupposes.  Furthermore, this revelation is distinct from the manifestation of his perfections which God has given to us in creation.  It is true to say that God “speaks to us in the works of nature, inasmuch as those works “reveal” his presence and activity; it is true, but it is metaphorical.  Revelation properly understood implies a personal intercourse between God and man, wherein God truly speaks–i.e., makes an assertion, which man accepts on God’s personal authority.

2.  Supernatural character of revelation

Hence revelation is supernatural–supernatural not only because it contains supernatural truths, but also because the very act whereby God reveals is beyond the ordinary course of nature.  In the ordinary course of nature God teaches us through created things, through the voice of conscience, through our own conscious needs and desires.  By supernatural revelation God teaches us himself.  “All thy children shall be taught of God” (Isa. liv 13).

3.  Mysteries

I have said that God’s revelation contains supernatural truths.  The essence of revelation does not demand that what is revealed should be hitherto unknown or otherwise unknowable.  Much of what God has revealed man may already have discovered by the natural light of reason; in which case the authority of divine teaching but confirms the conclusions of the human mind.  But even if the truth revealed is a mystery properly so called–that is, a truth which the human reason itself is incapable of discovering or of comprehending when it has ascertained it–yet it contains an element which is not new: the terms in which the revelation is made are familiar.  It is not true to say that the mysteries of our faith are unintelligible.  The unintelligible, the meaningless, precisely because it is meaningless, can have no relation to the human mind.  Thus an unknown language is unintelligible, because it conveys no meaning; it corresponds to no idea in consciousness.  A mystery is incomprehensible, if you will, but it is not meaningless; it conveys a very definite meaning.  The proposition that Jesus Christ is both God and man, that he is one person who has two natures, the human and the divine, is incomprehensible indeed; but it is not without meaning.  It is full of meaning, so full that man with his finite mind will never exhaust it. 

If divine revelation is supernatural in character, if it is beyond the ordinary course of nature, it follows that man can have no natural title or claim to it.  It is a grace, an entirely gratuitous gift of God.  Hence, although, as we saw in the previous section, the conditions of human existence indicate the need of some help from God for a universal and sufficient knowledge of religious truth, yet we cannot argue from this to the existence of a supernatural revelation.  Apologists rightly point out how wonderfully revealed truth harmonizes with the intimate needs and desires of mankind.  But it is too little to say: “This is exactly what we needed.”  It is far in excess of what we had any right to expect.  In this as in all else God has been more than just, he has been generously bountiful to his creatures.

4.  Manner of revelation

And how has this supernatural revelation been made?  Its history may be given in the inspired words of Holy Writ: “God who at sundry times and in divers manners spoke in times past to the fathers  by the prophets, last of all in these days hath spoken to us by his Son” (Heb. i 1).  “And Jesus spoke to his Apostles, saying: Going therefore, teach ye all nations; . . . teaching them to observe all things whatsoever I have commanded you; and behold I am with you all days, even to the consummation of the world” (Matt. xxviii 18-20).

Undoubtedly, had God so willed, he might have communicated his testimony directly to each member of the human race as soon as he was capable of receiving it.  The contention of Protestantism is (or was) that he does so.  There is no need to insist here on the inconveniences of such a method, had it been adopted; it would have led to hallucinations of every sort.  Sad experience has shown how easily men may be led to think that they are inspired.  But apart from any other reason, an individualistic revelation seems antecedently improbable because it would not be in keeping with what we know of God’s providential dealings with mankind.  God deals with man according to his nature; and man is naturally social.  This being so, we should have expected God to make his revelation to men as a body; and such in fact was the case.

“God spoke to the fathers [i.e., to the ancestors of the Jews whom St. Paul was addressing] by the prophets.”  Whether by visions, or by an interior illumination of the mind, or by the ministry of angels, God entrusted his message to certain chosen men, who in their turn were to deliver it to God’s chosen people.  Of that chosen people would be born Christ, the Word Incarnate, who was to complete the divine message and found on earth a universal kingdom in which God’s word would be carried to the ends of the earth until the end of time.

5.  Authentication of divine message

But God’s message must be authenticated, his messenger must present his credentials.  In vain will the seer claim divine authority if he cannot vindicate his mission.  Hence that all men might know that the words of the prophet were the words of God, he marked their teaching with unmistakable signs of its divine origin.  “They will not believe me,” protested Moses (Exod. iv 1), “nor hear my voice, but they will say: The Lord hath not appeared to thee . . . And the Lord said: Cast thy rod down upon the ground.  He cast it down, and it was turned into a serpent . . . that they may believe, said he, that the Lord God . . . hath appeared to thee.”  Leaving to its proper place, the discussion of miracles and prophecies as motives of credibility, we must remark here on the consistent appeal made by God’s messengers to these irrefragable evidences of their divine authority.  Suffice it to quote the words of the greatest of all the prophets, the Son of God himself: “Go and relate what you have heard and seen.  The blind see, the lame walk, the dead rise again, the poor have the gospel preached to them” (Matt. xi 4-5).  In answer to the Jews who ask him to say plainly if he is indeed the Christ, he says: “I speak to you, and you believe not; the works that I do in the name of my Father, they give testimony of me” (John x 24; cf. ibid., 37-38; xi 41-42).  Finally, we read of the Apostles of Christ who “going forth preached everywhere; the Lord working withal, and confirming the word with signs that follows” (Mark xvi 20).

6.  Revelation gradual

The revelation which God made to his chosen people was a gradual one.  Speaking to them “at sundry times,” he suited his message to the degree of culture and the condition of his hearers.  The promise that God would send a Redeemer was made at the very beginning, and that hope, fostered by repeated revelations through the Patriarchs and Prophets, was the heart and center of the Jewish religion.  Belief in the one true God was safeguarded by constant divine warnings against the idolatry of the surrounding nations and by detailed instructions for the manner of divine worship.  The precepts of the natural law were fully expounded in the Commandments and enforced by legal sanctions.  Gradually, in the books of the Old Testament beliefs concerning the future life, at first fragmentary and crude, become more and more detailed and definite.  Of the great mysteries of Christianity, the Incarnation and the Trinity, we find little more than mere traces–traces, however, which become clearer and clearer as the fullness of time approaches.  It was a period of preparation and expectation, during which truths were successively revealed according as they served to prepare men’s hearts to receive him who was to come.  But this progressive unfolding of God’s providential plan was not to be indefinitely prolonged.  At last Christ came, and with him the completion of God’s message of mercy.

7.  Definitive revelation in Christ

The Son of God became man and, living in the midst of men, showed by his fulfillment of the Messianic prophecies that he was indeed the divine messenger whom all generation had expected; and of his divine mission he gave still further proof–if further was needed–by the wonders that he worked.  The prophets of old had conveyed God’s word to the chosen people alone; Christ’s message was for the whole world.  Their revelation was but partial, to be supplemented by those who should come after; his was definitive and complete.  They were the creatural mouthpieces of God; he, while truly man, was God himself.

To the Jews first he preached his gospel, to the nation which throughout its history had been so signally favored by God; and by these he was rejected.  But from the beginning of his ministry he laid the foundations of his Church, collecting a chosen band of disciples who were to be witnesses of his gospel, not merely in Palestine, but throughout the whole world; they were his twelve Apostles.  These with infinite care and patience he trained for their important mission; to these he revealed “the mysteries of the kingdom of God” so far as they were then able to bear them, promising that when he should leave them he would send the Holy Ghost, who would teach them all truth.  To these, under the primacy of Peter, he gave special powers: a teaching authority such that to hear them was to Christ himself, that they might preach in its integrity the doctrine that they had received from his lips; powers of jurisdiction over all believers, that they might govern Christ’s spiritual kingdom on earth.

8.  Committed to the Catholic Church

In this way the Catholic Church was instituted, the visible, infallible society in which and through which the revelation of Christ was to be preserved and propagated.  The Church, the mystical body of Christ, was to perpetuate his work, to bear witness to the truth until the consummation of the world.  As the doctrine of Christ was the doctrine of the father who sent him, so the teaching of the Church is the teaching of Christ who instituted her.  Just as Christ had proved his divine mission, so the Church bears in the sight of all men the manifest marks of her divine origin.  “The Church herself,’ says the Vatican Council (Loc. cit., chapter iii), “by reason of her wonderful extension, eminent holiness and inexhaustible fruitfulness in all good things, her Catholic unity and invincible stability, is . . . an irrefutable witness to her own divine mission.”

IV.   PRELIMINARIES TO FAITH

1.  Faith man’s assent to revelation

Having studied the need, the nature and the manner of divine revelation, we now possess the elements necessary to understand the act whereby that revelation is accepted, the act of faith; and if in the pages which precede points of doctrine have been touched upon which are treated more fully elsewhere in this essay, it has been in order to provide data for the solution of the problem before us.

In fact, the nature of the act of faith has already been implied in what has been said about revelation.  Revelation is a divine testimony.  But if God has spoken, if he has testified to the truth of a statement, then it is man’s bounden duty to accept it by an act of belief, by an act of faith.  For our present purpose, then, it will be sufficient to describe the act of faith as that act whereby, on the authority of God, we give mental assent to a truth which he has revealed.  All that is involved in such an act will form the subject of the succeeding section, but here it should be noted that the motive of assent is not the intrinsic evidence of the statement itself, but the authority of God who makes it; in other words, I believe simply because God has said it.  Already it becomes clear that the act of faith cannot be made without certain preliminaries.  A motive, before it can give rise to an act, must first be perceived by the mind; the authority of God, then, must be known before I can make an act of faith.  I must know that there is a God, and that he has the authority–i.e., the knowledge and the veracity–which is to command my assent.  Moreover, by the act of faith, I give my assent not merely to a vague generalization–“whatever it may be that God has revealed”–but to a definite truth, or body of truth, which I know to have been revealed.  A further preliminary, therefore, is to know “the fact of revelation”–i.e., that God has revealed this or that truth to which I am required to give my assent.

2.  Evidence of credibility–Preambles of faith

We begin to see, then, that the act of faith is no “step in the dark.”  Faith is not an unreasonable credulity; still less is it a blind instinct to believe whatever one is told.  Man is a rational being, and God does not call upon him to do anything ill-befitting his nature.  It is reasonable, prudent, to believe what one is told by a trustworthy witness.  It is imprudent, and even foolish, to believe a statement purporting to be made by one whose existence is unknown, or at the best doubtful, or of whose knowledge and veracity, even if he exists, one has little or no guarantee.  St. Thomas Aquinas has been accused of being a Rationalist, but indeed he only vindicates the just rights of a reasonable being when he says: “Man would not believe (revealed truth) unless he saw that he must believe it” (Summa Theologica II-II, Q. 1, art. 4 ad 2).  Hence, before a man can reasonably and prudently believe a statement, that statement must be credible to him; he must have “evidence of credibility.”  That evidence of credibility he obtains from the knowledge of those preliminary truths which we have enumerated, called for the sake of convenience the “preambles of faith.”

3.  Fideism

How are we to know these preambles?  Should we not, some have suggested, rely for this knowledge on the authority of God himself, so that not only the act of faith but also its foundations should rest upon the firm ground of God’s infallible truth?  Even granting for the sake of argument, say the Fideists, that the existence of God and the fact of revelation can be discovered by the unaided human mind, yet even the Catholic Church is forced to admit that without revelation man finds it practically impossible to learn natural truths with certainty.  Is our faith, then, to rest upon so insecure a foundation?  It needs little reflection to see that such a process involves a vicious circle, and, far from strengthening the foundations of faith, removes them altogether.  How can I reasonably rely upon the authority of God when he reveals to me his existence, his omniscience, his veracity, the fact that he has revealed this or that truth, unless I am antecedently and independently of that same authority convinced that the revealing and truthful God exists?  Others have had recourse either to a blind instinct, or to an act of will, to bring about adherence to these preliminary truths.

All such systems betray that distrust of the human reason to which we referred in our second section.  The Church, we repeat, has no sympathy with those who disparage the powers of the human mind; nor is there any antagonism between reason and faith.  In the words of a famous preacher, “they are two sisters who dwell together in the same home.  The hospitable doors of our soul are opened to receive these two daughters of God.  Faith dwells on high, reason a little lower.  But faith will never kill her sister; she will not betray the hospitality accorded her to reign alone in the palace of them both” (Monsabre: Introduction, Conf. II).  “The use of reason,” says the Church in condemning Traditionalism, “precedes faith and must lead us to it” (Denzinger, Enchiridion, 1626).

The human mind, then, must discover for itself the truths which are the basis of faith, and these must be known with certainty.  It is not enough to conjecture with some degree of probability that there is a veracious God who has made a revelation.  While doubt concerning the preambles of faith remains the act of faith cannot be reasonable.  No man believes reasonably unless he sees that he must believe.

4.  Motives of credibility

But how are all men to acquire this certainty?  In the first place it is to be remarked that the existence of God, at least, can be certainly known by the light of human reason.  In fact, so clear are the indications of this truth that the Gentiles were upbraided by St. Paul as inexcusable for failing to recognize it.  Moreover, the arguments which prove the existence of God show also that he is all perfection, and therefore omniscient and incapable of deceiving.  As to the third preamble, the fact of revelation, we have seen that God accompanied his message with clear signs of its divine origin, particularly by miracles and prophecies, and that, moreover, the Catholic Church, founded by Christ for the specific purpose of teaching men what God has revealed, bears upon her unmistakable marks of her divine institution. 

5.  Miracles and prophecy

To set in full relief the arguments which show the divine origin of the Christian religion–to expound, in other words, the “motives of credibility”–is the function of the apologist, and therefore lies outside our scope.  These motives are many and varied; among them are some which alone are fully convincing, others which convince only by their accumulated force; some will appeal to all minds, others will appeal only to a few.  It is just, therefore, to that extent, that the apologist should accommodate his procedure to the mentality of those whom he seeks to persuade.  But of the absolute efficacy of at least one motive of credibility no Catholic may doubt, since it has been made the subject of an infallible definition in the Vatican Council, namely, miracles worked in confirmation of a divine mission.  “Anathema to him who says . . . that by miracles the divine origin of the Christian religion is not rightly proved” (De fide can. 4).  In the corresponding chapter the Council goes further; it declares that miracles and prophecies (I make no distinction here between miracles and prophecies, since the value of each, mutatis mutandis, is equal in showing the divine mission of the wonder-worker or the prophet.  In fact, a prophecy is simply a miracle of the intellectual order.) “are most certain signs of divine revelation, and suitable to the intelligence of all.”  They are suited to the intelligence of the learned as to that of the ignorant, to that of the scientist as to that of the layman, to the modern mind, too often supposed to be infallible, no less than to the mind of the ancients, too often presumed to be lacking in common sense.

That a miracle, granted the existence of God, is possible is shown elsewhere (Essay vii, Divine Providence).  If a true miracle, which is the work of God alone, is performed by a man as a sign that his teaching is divine, it argues an extraordinary intervention of divine power to vindicate his claim, and, since the true God cannot confirm falsehood, the argument is peremptory.  His statement is thus rendered credible on the divine authority.  It may not, however, be superfluous to add that the miracle as such does nothing more.  It is not an intrinsic proof of the statement made; it is a completely adequate motive of credibility.

6.  Certitude in preambles of faith

The human mind, then, is able to learn with certainty the existence of God; is able, by the proper investigation of the facts, to conclude that Christ is the bearer of a divine message, that he founded an infallible Church for the purpose of propagating that message; and finally, by the process indicated in apologetics, to conclude that the Catholic Church is that divinely appointed teacher of revelation.  These things, I say, can be known and proved, and by those who have the requisite leisure, opportunity and ability, are actually known and proven with all the scientific certainty of which the subject is patient.  The preambles of faith, therefore, rest upon the solid ground of human reason.

7.  Relative certitude

But while the human mind can satisfy itself by rational demonstration of the existence of God, and by historical investigation of the “fact of revelation,” it remains true that for a great proportion of the human race such a process of scientific demonstration is a practical impossibility.  A secure conviction that a good God exists is obtainable by all men, and by the large majority is actually obtained.  But how many are able, besides justifying that conviction to themselves, to construct a scientific proof of the existence of God which satisfies all the demands of human reason, with all the apparatus of objection and answer which is needed by the modern apologist?  Most men believe in the existence of God because they have satisfied themselves, by reasons which for them are sufficient, that God really does exist.  Again, the divine origin of the Christian religion, the divine character of the Catholic Church, being attested by so many motives of credibility, is known by all Catholics, can be recognized by non-Catholics.  But relatively few Catholics have either the leisure or the ability to investigate the historical documents, to sift for themselves the evidence required for a scientific historical demonstration: relatively few non-Catholics would have the opportunity of thus verifying the claims of the Catholic Church.  Moreover, the difficulty in the way of such scientific certitude is infinitely increased when we consider the condition of the uneducated and the young.  Can these make no act of faith until they have completed a course of philosophy, until they have satisfied their minds by answering every objection that can be made against the existence of God, proved the divinity of the Christian religion by a rigid demonstration, and thus arrived at perfect evidence concerning the preambles of faith?

Such perfect scientific evidence is unnecessary.  The reason why one must, before believing a statement, be convinced of the existence and trustworthiness of the witness who makes it, is that otherwise the assent given would be unreasonable, imprudent.  Thus it is imprudent to believe a statement supposed to have been made even by a most knowledgeable and trustworthy person, if there is reasonable doubt as to his having made it.

I say, advisedly, if there is reasonable doubt, because there are doubts which are unreasonable, imprudent.  Nowadays, at any rate, whatever may have been the case years ago, it is unreasonable to doubt the safety of traveling by rail.  It is unreasonable to doubt a proposition which you have clearly demonstrated simply because an objection is made to it which, by reason of your lack of ability or technical knowledge, you are unable to solve.  Briefly, without going into the vexed question of certitude and its various kinds, we may remark that there is a state of mind which a reasonable man demands before he will engage upon any serious undertaking.  Call it moral certitude if you will; I prefer to call it a prudent conviction.  Complete scientific evidence in many cases, either for circumstantial or personal reasons, he cannot have.  He asks those who are competent to know, in whose judgment he has full confidence, and with the conviction thus obtained he sets out upon his task.  Absolutely speaking, he may have been deceived; but in the circumstances he acted prudently; it would have been imprudent, unreasonable to doubt.

And here follows a consequence of vital importance for the solution of our question.  What is prudent in some circumstances is imprudent in others; what is prudent for one person is not prudent for another.  This state of mind, which I have called “prudent conviction,” is not absolute but relative (Obviously this view has nothing in common with the theory of “relative truth,” according to which a proposition objectively true to one is false to another.  I am speaking here not of objective truth but of a subjective state of mind.)  So, for example, it is prudent for the unlearned to believe implicitly the teaching of those who “ought to know.”  A child acts prudently on the advice, however misguided, of his mother.  School-children believe what their teachers, however incompetent, teach them; and to act upon such information is prudent and reasonable–for children.  In fact, they would be imprudent to act otherwise.

And now let us apply these principles to the question before us.  In order to make a reasonable act of faith the prospective believer must achieve a prudent conviction concerning the preambles of faith: a conviction–i.e., he must be convinced of the existence of God and the fact of revelation: a prudent conviction–i.e., there must be no reasonable doubt.  Such a state of mind, then, is compatible with unreasonable doubts such as we have exemplified above.  Thus a child who learns from his teacher, or from his catechism, that there is a God who has revealed certain truths through his Church, of which the parish priest is an official representative, has a prudent conviction regarding the preambles sufficient for a reasonable act of divine faith.  Again, motives of credibility which would not convince the scientist, to the unlearned may carry a conviction upon which he could prudently rely.  Hence, a scientific demonstration of the preambles, so far from being a necessary preliminary to a reasonable act of faith, is in most cases impossible; in those cases, therefore, it would be unreasonable to demand it.

Nevertheless, in all cases the legitimate demands of reason are met.  Reason demands that no man believe a thing unless he see it to be credible.  Even in the case of the child, even in the case of the unlearned, whatever be the objective reliability of his grounds for admitting the existence of God or the fact of revelation, the conclusion to which he is led–namely, the judgment of credibility–is perfectly evident.  He concludes that it is evidently reasonable to believe on the authority of God a truth, or a group of truths, which he is prudently convinced that God has revealed.  But it should be carefully noted, even now, that the motives which have led to the “judgment of credibility” are not the motive of faith.  The act of faith remains yet to be made, and its motive is quite distinct; it is the authority of God who reveals.

8.  Other factors in the approach to faith–The function of the will

When the inquirer has reached the stage at which he regards revealed truth as “credible,” when, further, he has realized his obligation to believe, he is on the threshold of faith.  But before we consider the act of faith itself, we have still to take into account other important factors in the approach to it.  In what has been said hitherto we have considered only the intellectual activity of man; and we have purposely confined our attention to this aspect of the question in order to stress the essentially reasonable character of submission to divine revelation.  But man is not a mental machine.  When he thinks of a subject he does so because he wills to think of it.  As we shall see later, the will plays a prominent and essential part in the act of faith itself.  But also in the preparation for faith good-will is absolutely necessary.  Moreover, man has various emotions and desires which to a greater or less extent are under his control; these too must be taken into account.  It is not simply the human mind that prepares itself for faith; it is the whole man, a vital unity, with all the complex interaction of his mental, volitional, and emotional powers.

The first thing necessary in the approach to faith is attention to the subject of religion; the inquirer must first make up his mind to think about God and his duties in God’s regard.  And here, besides the effort of will, the emotional factor may well enter to attract or to repel.  Some have begun their inquiry simply out of affection for a Catholic friend whose good opinion they valued; others have desisted when they saw that such inquiry would lead to self-denial.  Some have been first attracted to the Catholic Church by the beauty of her ceremonial; others have been repelled by the squalor of an ill-kept church.  Thus the most insignificant circumstance may exert its effect, inclining a man this way or that; but finally it is the will that directs the mind to God.

It is not only in the initial impulse, however, but throughout the preliminary stages too, that these factors exert their influence.  Distractions must be firmly set aside that the mind may devote its attention to a serious and difficult subject; prejudices must be overcome so that the full force of the motives of credibility may be appreciated; the temptation to dally with sophistical objections when they are seen to be groundless must be suppressed; unworthy considerations of self-interest, pride and human respect must be excluded lest they interfere with the earnest inquiry after truth.  In short, there are innumerable ways in which desires and feelings may help or hinder man in his preparation for faith.  The will cannot make a thing to be true which is false; the will cannot give force to an invalid argument.  But it can and must prevent extraneous considerations from obscuring the issue, and exclude from the mind anything that may distract a serene and unbiased attention to the arguments proposed.  In the study of a purely speculative subject there is little danger of such interference; one is not liable to unreasonable prejudices in the solution of an algebraic problem.  But religion is vitally connected with man’s moral duties, and for that very reason a purely unprejudiced and rational study of it is particularly difficult.  If a man is to devote himself to it wholeheartedly and with unruffled mind, he needs above all things good-will.

9.  Grace

There remains the last, and yet really the first and most important factor.  With the intellect of a Plato, with the iron self-control of a Stoic, with all the good-will of which man is capable, he can do nothing to prepare himself for faith without the help of God’s grace.  “No man cometh to me unless the Father draw him.”  Man’s destiny is a supernatural one, entirely beyond his natural powers to achieve.  His acts, to be salutary–that is, to be conducive to his eternal salvation–must be supernatural, must have a quality, a modality, which raises them above their natural power and value, making them proportionate to a supernatural end (See Essay xvii, Actual Grace).  It is by the act of faith that man first sets himself in the path of salvation, and, as will be seen, that act must be supernatural.  But even before this vital step is taken man must be guided by God’s grace.  God’s supernatural providence, which wills all men to be saved and to come to the knowledge of the truth, watches over all men, guiding them gently, but surely, to himself.  The child who learns his religion from his mother, whose mind is gradually opened to the wonders of God’s revelation, is acting under the impulse of God’s grace.  The unbeliever who becomes conscious of a desire to know God, who earnestly and perseveringly, in spite of obstacles, seeks after the truth, is being led, enlightened and inspired by supernatural grace.  The eloquence of St. Paul would not have converted a Lydia had the grace of God not opened her heart to hear his words.  The Apostle may plant the seed and tend it carefully, but it will not grow unless God give the increase (Cf. Acts xvi 14; 1 Cor. iii 4-6).

In all these preliminaries, therefore, man must do his part.  He must endeavor, with good-will, to see God’s truth is credible; it is his duty and his right as a rational being.  But he must not rely upon himself.  “Our sufficiency is from God” (2 Cor. iii 5).  His very good-will must derive from him who “worketh in us both to will and to accomplish” (Phil. ii 13).  The urge of passion, a deep-seated prejudice, a whole complex of circumstances for which he may be but partly or even in no degree responsible, may blind him to the truth.  For such a one the grace of enlightenment is at hand, if he will but accept it.  His prayer must be that of the blind man: “Lord, that I may see.”  The answer and the result will be the same: “And immediately he saw, and followed him” (Cf. Matt. xx 30-34).

V.   THE ACT OF FAITH

1.  Definition of faith

In the previous section we accompanied the believer in his progress towards the act of faith until the stage at which, having acquired a firm conviction concerning the preambles of faith, he forms an evident “judgment of credibility”: “This truth, which I am convinced has been revealed by God, is to be believed on God’s authority.”  Passing to a judgment of the practical order, he says: “I must believe it.”  Then, and not till then, he proceeds to give his assent to the revealed truth: “I believe this truth because God has revealed it.”  This assent is the act of divine faith which we must now study.

The subject is of such vital importance that our definition of the act of faith must be taken from the infallible pronouncement of the Vatican Council.  The Council directly defines the virtue of faith, but in doing so it necessarily defines the act: “Faith . . . is a supernatural virtue whereby, inspired and assisted by the grace of God, we believe that the things which he has revealed are true; not because the intrinsic truth of the things is plainly perceived by the natural light of reason, but because of the authority of God himself who reveals them, and who can neither be deceived nor deceive.”

2.  Motive, the authority of God

Faith, then, is an act whereby we believe something to be true.  It is an asset to truth, and therefore an act of the intellect: for truth is the object of the intellect (Cf. the oath against Modernism: “Faith . . . is a true act of the intellect.”)  There is, however, this important difference between the assent of faith and the assent of immediate knowledge.  The assent in the latter case is caused by the perception of the intrinsic truth of the statement; so that when it is made I say: “I see; of course, that must be so”; and, when once the truth is seen, nothing further is required to gain my assent.  In the case of faith, I see indeed–otherwise there could be no assent–but I do not see within the truth itself.  I understand the terms of the revealed proposition, but neither the analysis of those terms nor my own experience assures me that they should be connected.  The ground, or the “motive,” of my assent to the proposition is extrinsic to it, and that motive is the authority of God, who tells me that it is true.  In both cases there is evidence: in the former the evidence is intrinsic, in the latter it is extrinsic.  The believer sees the truth, says St. Thomas, “as credible; . . . for he would not believe unless he saw that he must believe” (S. Theol., II-II, Q. 1, art. 4 ad 2).

3.  The will in the act of faith–a free act

I have said that when once the inward truth of a proposition is seen, nothing further is required to evoke the assent of the mind; it is drawn of necessity to adhere to its connatural object.  But without that internal evidence the mind, of itself, is powerless to assent.  “Faith,” says St. Paul, “is the evidence of things that appear not” (Heb. xi. 1).  Revealed truth is not seen in itself; it is seen as credible, as clothed, so to speak, in the garment of divine authority.  Invested with such authority, it becomes indeed a fit object for intellectual acceptance; but the intellect alone, eager to “read within” (intus-legere) the truth, makes no spontaneous move to accept it.  It is here that the intervention of the will becomes necessary.  It has been seen in the previous section that the will has an important function in the preliminaries to faith.  To arrive at the judgment of credibility the believer must focus his attention upon the motives of credibility and set aside all that might distract from their unbiased consideration.  All this needs a firm and constant effort of will.  But in these preliminary stages the will has no direct causative influence upon the assent of the mind (This, of course, is true only of those preambles of which rational demonstration is given.  If the preambles are accepted–as they often are–on human testimony, then the function of the will is the same as in every act of faith, whether human or divine).  The intervention of the will in the act of faith itself is of a different and more direct character.  The act of faith, though, as we have seen, it is elicited by the mind, is caused by an act of will.  By faith, says the Vatican Council, “man yields a voluntary obedience to God himself.”  The mind sees the revealed truth as credible, and the will bends the mind to accept it.

Now it is important at once to preclude a possible misunderstanding of the function of the will in the act of faith.  The will cannot make the mind believe anything it chooses; it is not that “the wish is father to the thought.”  Before the mind can accept a statement, even at the behest of the will, the statement must be “credible”; it must be attested by a trustworthy witness; and, moreover, it must not be nonsense.  Nonsense is meaningless and can have no relation to the mind.  Briefly, a revealed statement can be accepted by the mind provided that it fulfills the conditions necessary to render it credible–i.e., fit for intellectual acceptance.  It is seen to be not unfit for acceptance because it has an intelligible meaning; it is seen to be positively fit for acceptance because it is attested by an infallible witness.  In fact, since the witness in this case is God himself, who has a right to our homage and obedience, the fitness is presented as a positive duty.

4.  Motive of faith further explained

The will therefore now deliberately intervenes and commands the assent of the mind to revealed truth; and the motive of the act is the authority of God who attests that truth.  This motive, it should be remarked, is one which appeals to both mind and will, but under different aspects.  To the mind it appeals as endowing the statement with credibility; to the will it appeals as a divine perfection to be worshipped: his love in revealing to be repaid by a loving acceptance on our part, his wisdom and his veracity to be adored by an unquestioning homage (The act of faith, therefore, involves an act of trust, of confidence in God’s authority.  But this trust is not the act of faith itself; it is anterior to it because it belongs to the motive of my assent.  As a consequence of my faith in what God has revealed I may then make a further act of confidence in God that he pardons my sins; this is an act of hope.  The Protestant error concerning the “faith that justifies” consists in confusing hope with the faith which it presupposes.  But see Essay xvi: Sanctifying Grace).  “Since man,” says the Council which is our infallible guide in this matter, “is utterly dependent upon God as upon his Creator and Lord, and since created reason is absolutely subject to uncreated Truth, we are bound, by faith in his revelation, to yield him the full homage of our intellect and will.”  Hence, although the act of faith is an intellectual act, yet it is also an act of homage which is in the power of the will to withhold.  By faith “man yields free obedience to God.”  To explain the freedom and other properties of faith, it is necessary to examine a little more closely the precise nature of its motive, the authority of God (Here a preliminary remark may not be out of place.  As in many matters of theology, where it is a question of explanations, so in this matter theologians differ.  The explanation of the act of faith involves the science of psychology which, although, or perhaps because, it deals with ourselves, is full of difficulties and mysteries.  It is fair, therefore, to warn the reader that while all Catholics are agreed–as they must be–that the motive of faith is the authority of God, not all are agreed as to the manner in which this should be explained.  The view here put forward appears to the writer a reasonable one, and is held by many theologians of repute).

It might seem at first sight that if a man is firmly convinced that a statement has been made by one who is certainly telling the truth, then he cannot possibly withhold his assent to it; nor is it apparent that such assent would be an act of homage to his informant.  If a man accused of murder admits a fact which is damaging to his case, the jury–granted that they find no other reason for his admission–cannot but believe his testimony.  And apart from all discussion as to the freedom of such an assent, by no conceivable standard could such belief be termed a homage to the veracity of the witness.  The jury accept his statement because they know that in the circumstances it must be true.  Of a like nature is the credence that we may give to an historian whom, however otherwise unreliable, we have proved by the application of tests to be here and now telling the truth.  Critical students of history rely upon human testimony, but their acceptance of it implies no personal compliment to the narrator of the event.  They believe that this happened because, and in so far as, they know that he is saying what is true.  Is not the case the same with the act of divine faith?  I know that God has revealed the Trinity.  I know that God is Truth itself.  Surely the logical conclusion is inevitable:  the Trinity is true.  Here is no free acceptance of God’s word, no free homage to his Person.  I am forced by the laws of evidence.

But there is a radical difference between the assent of divine faith and the assent given under the circumstances above described.  The jury believe the witness, the historian believes his informant, because and in so far as they know him to be relating what is in conformity with reality.  The motive of their assent is the evidence that they have of the truth of the statement; and such assent is probably not a free act; it is certainly no personal compliment to the witness.  The believer accepts a revealed truth not precisely because he knows that God has revealed it and knows that God is infallible.  This knowledge is the necessary condition, but it is not the motive of his faith.  He believes because God, who is infallible, has said it.  The difference is perhaps subtle, but it is important.  The motive of the act of divine faith is not my knowledge of that authority as accrediting revealed truth, however certain, however evident that knowledge may be, but the divine authority itself.  My knowledge is finite, my knowledge is fallible.  God’s authority is infinite; God can neither deceive nor be deceived.  If, when I believe, I rely upon my knowledge, I rely upon what is human; if I rely upon God’s authority I rely upon what is divine.  In the act of divine faith the believer abstracts from the arguments which have led him to the judgment of credibility.  They were a necessary preliminary; they were, if you will, the tinder that lit the torch.  But the torch burns now by its own brilliance; the light of God’s authority illumines revealed truth with its infinite radiance; and this is the motive of faith: I believe because God has said it.  Reason has led me to faith.  Reason has told me that God’s revealed word is credible, and in accordance with her advice I freely and unreservedly submit myself to the guidance of his Truth.

An instructive incident in the life of the Lord illustrates the nature of divine faith.  The Pharisees, as is well known, were constantly rebuked by our Lord for their unbelief.  They had seen, as others had seen, evident signs that Christ spoke the words of God; and yet they stubbornly refused to believe him.  One day after they had made one of their frequent attempts to discredit him (Matt. xix 3), he took a little child and said: “Amen I say to you, whosoever shall not receive the kingdom of heaven as a little child, shall not enter it” (Mark x 15).  The act of divine faith has more in common with the trusting belief of a child in his mother than with the assent of the critical historian.  For the child it is enough to know that his mother has said it, and he believes on that authority.  His assent is a prudent one, for he has motives of credibility which for him are sufficient; everything leads him reasonably to suppose that his mother knows everything and would not deceive him.  But when he believes, he believes simply and solely because his mother has said it.  He does not advert to the reasons which have led him to regard his mother as trustworthy.  His belief is an unaffected and trusting homage of love to his mother.  So also in the Act of Faith which every Catholic child recites: “O my God, I believe . . . because thou has said it, and thy word is true.”  To the motives of credibility the child does not advert; he has probably forgotten them.  But the motives of credibility are not the motives of his faith.  He relies not upon them, but upon the authority of God itself.  What is true of the child is true of the Christian adult; and this the experience of each will confirm.  When he makes an act of faith, he thinks not of the proofs of the existence of God, not of the miracles which Christ worked, but of the authority of God, who can neither deceive nor be deceived.

This is why faith is a “theological” virtue, this is why faith is an act of free obedience to God; this, finally, is the reason for its sovereign certitude.

5.  The certitude of faith

The certitude of faith is supreme because the believer’s assurance rests upon a ground more secure than all human science, upon the infallible authority of God.  “If we receive the testimony of man,” says St. John (1 John v 9-10), “the testimony of God is greater”; infinitely, unspeakably greater, since God is very Truth.  But, as in regard to the freedom of the act of faith so also in regard to its certitude, a difficulty often arises from a misconception of the precise motive of faith.  It is sometimes urged that since no chain is stronger than its weakest link, therefore the assent of faith can enjoy no greater certitude than the assent given to any of the preambles of faith which are its foundation.  Metaphors are misleading here.  Even the word “foundation” may lend itself to misunderstanding.  The preambles of faith are the foundation of faith in the sense that they are a necessary prerequisite.  But they are not its foundation in the sense of supplying the security of the edifice.  The metaphor of the chain is no less fallacious.  There is no continuous “chain” of reasoning that leads from the first argument which proves the existence of God to the truth, for example, that in one God there are three Persons.  If the act of faith were the logical conclusion of such a chain, then evidently that conclusion could have no greater weight than is warranted by the series of arguments that lead to it.  But the act of faith is not an inference from preceding arguments.

The series of truths which we have called the preambles of faith leads logically to the judgment of credibility, but no further.  I aver, in view of my previous reasoning, that it is reasonable, prudent, in fact obligatory, to believe that, e.g., there are three Persons in one God.  I then proceed, impelled not by my previous reasoning, but by God’s authority, to believe it.  I believe it, not precisely because and in so far as I know that God has revealed it, but because God has revealed it.  Hence the firmness of my assent is measured not by the cogency of any one, or indeed of the sum, of the reason which led me to judge the truth as credible, but by the infinite weight of the divine authority which is the motive of my faith.

But although the certitude of faith is supreme, supreme as is the divine authority upon which it is based, yet the mind of the believer is not completely satisfied.  Under the influence of the will it holds firmly to the truth; but within the truth it does not see; and nothing save vision can satisfy the mind.  Faith is an evidence–i.e., a firm conviction–but it is a conviction “of things that appear not.”  As long, then, as intrinsic evidence is denied, the mental assent is not spontaneous and requires the concurrence of the will.  Hence it is misleading to compare the state of mind of the believer with the complete repose of the mind in a truth clearly demonstrated, or with the evidence of the senses.  In the latter case there can be little or no temptation to doubt.  The believer, on the other hand, precisely because he does not see within the truth, may be subject to many such temptations.  But temptations are not doubts, and the believer is able by an effort of will to dispel them, to concentrate his attention upon the infallible motive of his faith, and thus to achieve a state of security from error as superior to that of human knowledge as the Truth of God infinitely transcends the fallible reason of man. 

6.  The supernatural character of faith

The whole process of the act of faith, such as we have described it, does not seem, absolutely speaking, to exceed man’s natural powers.  If we consider those powers in the abstract, there seems to be no reason why, granted that God has made a revelation, man should not be able for himself to investigate the preambles of faith, naturally to recognize his obligation to accept it, and finally to believe on God’s authority the truths that he has revealed.  But even if we grant this to be physically possible, we have seen that the difficulties which occur even in the preliminary stages are such as to render it extremely unlikely of achievement, without the help of God’s grace.  When, moreover, we consider that the act of faith, being the initial step in man’s progress towards his supernatural end, must itself be supernatural, the need for grace becomes quite imperative.

7.  Grace

We must now, therefore, give our attention to those words of the Vatican definition which we have hitherto neglected.  “This faith,” says the Council, “which is the beginning of man’s salvation, is a supernatural virtue, whereby, inspired and assisted by God’s grace, we believe,” etc.  And later in the same chapter, quoting the Council of Orange (529) the Council asserts the absolute impossibility of a salutary faith “without the illumination and inspiration of the Holy Spirit, who gives to all men sweetness in accepting and believing the truth.”

Grace is necessary for the act of faith, in the first place, to make it supernatural; to give it that quality which makes it conducive to a supernatural end, in other words, to make it salutary.  If that supernatural character is needed–as we have seen that it is–even in the preliminary steps to faith, still more is it needed in the very act by which man submits to God’s authority.  “By grace,” says St. Paul (Ephes. ii 8), “you are saved through faith, and that not of yourselves, for it is the gift of God.”  For faith man must strive to his utmost; he must use all human endeavor to learn the truth and to submit to it.  But all his striving, all his endeavor, would be utterly useless without the grace of God.  He might even–we have surmised that it is not impossible–make an act of faith unaided; but that act would not serve for his salvation unless it were made under the inspiration and assistance of God’s grace.  It must be inspired by grace.  God does not wait until man conceives the desire to believe; he puts that desire supernaturally in his heart.  It must be assisted by God’s grace.  In the very act of submission to God’s truth, the mind is enlightened, the will is strengthened by God, who works in us “to will and to accomplish.”

The grace of God is essential; but to none is it ever lacking.  If even during man’s progress toward faith God enlightens the mind and strengthens the will, anticipating every act with his grace, still more abundantly, when the act of faith itself is to be made, will God give his supernatural help.  It is not the lack of grace that man should dread, but rather his own power to resist it.

But grace does more than make the act of faith supernatural; it renders it easy and delightful.  The Holy Spirit gives “sweetness in believing.”  Grace enlightens the mind, setting in vivid relief the desirability of paying intellectual homage to God, giving to it a supernatural insight into the meaning even of mysteries, and into the treasures of grace and glory which will be the reward of our faith.  Grace helps the will to adhere firmly to God’s word, putting aside all considerations of self-interest, all distractions of worldly things, to cleave to God, the inexhaustible source of every good (The effects which, in those who have the supernatural virtue of faith, proceed from that virtue are produced in others by actual grace. Cf. Essay xviii: The Supernatural Virtues).

8.  Faith God’s gift–Perseverance in faith

In the fullest sense of the term, therefore, faith is God’s gift.  Hence it is for man to treasure and preserve it.  Until we see God face to face the mind will be restive, and temptations to doubt will be frequent.  The will must be prompt to reject them, and in this task man has always the abundant help of God’s grace.  He who has once committed himself to the keeping of God’s Truth need not fear that he will be deserted in time of temptation.  But he must do his part.  He must take all those measures which are humanly possible to guard his treasure against attack.  The mind of man is fickle; error seduces by its very novelty, sophistical reasoning by its display of ingenuity.  The Church, therefore, while she encourages her more learned children to study, in order to refute, the written works of those who attack the faith, wisely forbids the dissemination, and above all the indiscriminate reading, of such books.  She knows well that many who have the intelligence to understand an objection have not the ability to find, or even to understand, its answer; that not all the faithful have the leisure or the power to meet reason with reason and learning with learning, and to rebut the objections so lightly made.

Those of the faithful who are troubled with such difficulties will do well to meditate upon these infallible words of the Vatican Council: “Although faith is above reason, there can never be any real discrepancy between faith and reason; since the same God who reveals mysteries and infuses faith has bestowed the light of reason on the human mind, and God cannot deny himself, nor can truth ever contradict truth.  The false appearance of such contradiction is mainly due, either to the dogmas of faith not having been understood and expounded according to the mind of the Church, or to the inventions of opinion having been taken for the verdicts of reason.” 

A further duty regarding perseverance in faith arises from what was said in the previous section.  It was there established that in order that the act of faith may be reasonably made it is sufficient to have a conviction concerning the preambles which, relatively to the circumstances of the individual, is prudent.  But what is the duty of the child, for instance, when he grows to manhood and discovers–as he may–that the motives upon which he relied for his judgment of credibility no longer satisfy him?  Is he to give up his faith until he has once more gone over the preliminary ground and satisfied himself concerning the preambles?

The answer of the Church as far as Catholics are concerned is peremptory: a Catholic can never have a just reason for abandoning the faith that he has once embraced.  And the first reason of this is that the Catholic has constantly before him an absolutely, and not merely a relatively, sufficient motive of credibility–namely the Church herself, divinely instituted, and assuring her children “that the faith which they profess rests on the most secure foundation” (Vatican Council, loc. cit., chap. iii).  The second reason is that faith is not only a supernatural gift of God, but is accompanied by the graces necessary to preserve it.  God’s providence will not allow the faithful to lack the helps which they need to protect their faith.  The ever-watchful Father, to whom his children daily pray, “Lead us not into temptation,” will never allow them to be in such circumstances that the loss of their faith would be inculpable.  Whatever be the greater or lesser degree of blame that may attach in individual cases, whatever be the mysterious means that God may use to protect his faithful ones, it is certain that “God does not abandon us until we first abandon him” (St. Augustine, De natura et gratis, c. 26).

It is clear, then, that in this matter the Catholic has serious duties.  Not only must he avoid temptations against the faith, not only must he pray for an increase of faith, but he is bound to take care that his mental development in secular branches of study shall be accompanied by equal development in the knowledge of his religion.  If he feels difficulties regarding fundamentals it is his duty to inquire of those who are able to solve them; and here he needs a humility of mind which recognizes that what he does not know is well known to many others.  There can be little doubt that many defections from the Church are due to a culpable lack of knowledge–culpable because the ordinary means of information upon this important matter, whether they be Catholic books, sermons, or instructions, have been culpably neglected.

But it is otherwise for those who belong to non-Catholic religious bodies.  None of these possesses, or indeed claims exclusively to possess, those characteristic marks of divine institution which so clearly distinguish the Catholic Church.  Although members of such bodies may indeed assent by divine faith to some truths which are revealed by God, yet that very grace of faith, which strengthens Catholics in their adherence to the Church which Christ has instituted as the pillar and the ground of truth, will lead others to correct their errors and to submit to the infallible teacher of God’s word.  The essential differnce in this matter between the position of Catholics and that of others is that whereas other religious bodies do not claim to be divinely instituted as the only infallible teacher of divine revelation, Catholics by their very faith profess that the Church is their divinely appointed guide.  As Tertullian said to the unbelievers of his day, “We need no curious searchings, when we have Jesus Christ; we need no further inquiry, when we have the gospel.  When we believe, we need to believe nothing more.  For this we believe at the very beginning, that there is nothing more to believe” (De praescr., c. 9).

9.  Necessity for salvation

A word in conclusion on the necessity of the act of faith.  That in all adults a supernatural act of divine faith is necessary as an indispensable means of salvation is the doctrine of the Catholic Church, and may be readily inferred from all that has been said concerning faith and supernatural revelation.  The primary truth of that revelation is that man is called to a supernatural destiny which consists in the vision of God face to face.  Of this destiny man could know nothing without revelation, and knowing nothing could never strive for it.  Hence, in all who are able to act rationally and to think for themselves the first and indispensable step towards salvation is their recognition, by an act of divine faith, of God as their supernatural end.  “Without faith,” says St. Paul, “it is impossible to please God” (Heb. xi 6).  That act of faith, it is clear, must embrace at least implicitly every truth that God has revealed, for the motive of faith, the authority of God, applies equally to them all.  As to the minimum that must be known, and therefore believed explicitly, so that even its inculpable ignorance would exclude from the hope of salvation, it is commonly held that the two truths mentioned by St. Paul (Loc. cit.) are sufficient: “He that cometh to God must believe that he is, and is a rewarder of them that seek him.”  But however few, however many be the truths believed, they must be accepted by an act of faith strictly so called.
