Q: Whether Faith, Among the Fruits, Responds to the Gift of Understanding?

A: On the contrary,
The end of a thing is its fruit. Now the gift of understanding seems to be ordained chiefly to the certitude of faith, which certitude is reckoned a fruit. For a gloss on Gal. 5:22 says that the "faith which is a fruit, is certitude about the unseen." Therefore faith, among the fruits, responds to the gift of understanding.

I answer that,
The fruits of the Spirit, as stated above (I-II, Q. 70, A. 1), when we were discussing them, are so called because they are something ultimate and delightful, produced in us by the power of the Holy Ghost. Now the ultimate and delightful has the nature of an end, which is the proper object of the will: and consequently that which is ultimate and delightful with regard to the will, must be, after a fashion, the fruit of all the other things that pertain to the other powers.

Accordingly, therefore, to this kind of gift of virtue that perfects a power, we may distinguish a double fruit: one, belonging to the same power; the other, the last of all as it were, belonging to the will. In this way we must conclude that the fruit which properly responds to the gift of understanding is faith, i.e. the certitude of faith; while the fruit that responds to it last of all is joy, which belongs to the will.

Reply Obj. 1: Understanding is the fruit of faith, taken as a virtue. But we are not taking faith in this sense here, but for a kind of certitude of faith, to which man attains by the gift of understanding.

Reply Obj. 2: Faith cannot altogether precede understanding, for it would be impossible to assent by believing what is proposed to be believed, without understanding it in some way. However, the perfection of understanding follows the virtue of faith: which perfection of understanding is itself followed by a kind of certainty of faith.

Reply Obj. 3: The fruit of practical knowledge cannot consist in that very knowledge, since knowledge of that kind is known not for its own sake, but for the sake of something else. On the other hand, speculative knowledge has its fruit in its very self, which fruit is the certitude about the thing known. Hence the gift of counsel, which belongs only to practical knowledge, has no corresponding fruit of its own: while the gifts of wisdom, understanding and knowledge, which can belongs also to speculative knowledge, have but one corresponding fruit, which is certainly denoted by the name of faith. The reason why there are several fruits pertaining to the appetitive faculty, is because, as already stated, the character of end, which the word fruit implies, pertains to the appetitive rather than to the intellective part.

QUESTION 9

OF THE GIFT OF KNOWLEDGE (In Four Articles)

We must now consider the gift of knowledge, under which head there are four points of inquiry:

(1) Whether knowledge is a gift?

(2) Whether it is about Divine things?

(3) Whether it is speculative or practical?

(4) Which beatitude responds to it?
Q: Objection 1: It would seem that, among the fruits, faith does not respond to the gift of understanding. For understanding is the fruit of faith, since it is written (Isa. 7:9) according to another reading [*The Septuagint]: "If you will not believe you shall not understand," where our version has: "If you will not believe, you shall not continue." Therefore fruit is not the fruit of understanding.

Obj. 2: Further, that which precedes is not the fruit of what follows. But faith seems to precede understanding, since it is the foundation of the entire spiritual edifice, as stated above (Q. 4, AA. 1, 7). Therefore faith is not the fruit of understanding.

Obj. 3: Further, more gifts pertain to the intellect than to the appetite. Now, among the fruits, only one pertains to the intellect; namely, faith, while all the others pertain to the appetite. Therefore faith, seemingly, does not pertain to understanding more than to wisdom, knowledge or counsel.
Q: Whether Knowledge Is a Gift?

A: On the contrary,
Knowledge is reckoned among the seven gifts (Isa. 11:2).

I answer that,
Grace is more perfect than nature, and, therefore, does not fail in those things wherein man can be perfected by nature. Now, when a man, by his natural reason, assents by his intellect to some truth, he is perfected in two ways in respect of that truth: first, because he grasps it; secondly, because he forms a sure judgment on it.

Accordingly, two things are requisite in order that the human intellect may perfectly assent to the truth of the faith: one of these is that he should have a sound grasp of the things that are proposed to be believed, and this pertains to the gift of understanding, as stated above (Q. 8, A. 6): while the other is that he should have a sure and right judgment on them, so as to discern what is to be believed, from what is not to be believed, and for this the gift of knowledge is required.

Reply Obj. 1: Certitude of knowledge varies in various natures, according to the various conditions of each nature. Because man forms a sure judgment about a truth by the discursive process of his reason: and so human knowledge is acquired by means of demonstrative reasoning. On the other hand, in God, there is a sure judgment of truth, without any discursive process, by simple intuition, as was stated in the First Part (Q. 14, A. 7); wherefore God's knowledge is not discursive, or argumentative, but absolute and simple, to which that knowledge is likened which is a gift of the Holy Ghost, since it is a participated likeness thereof.

Reply Obj. 2: A twofold knowledge may be had about matters of belief. One is the knowledge of what one ought to believe by discerning things to be believed from things not to be believed: in this way knowledge is a gift and is common to all holy persons. The other is a knowledge about matters of belief, whereby one knows not only what one ought to believe, but also how to make the faith known, how to induce others to believe, and confute those who deny the faith. This knowledge is numbered among the gratuitous graces, which are not given to all, but to some. Hence Augustine, after the words quoted, adds: "It is one thing for a man merely to know what he ought to believe, and another to know how to dispense what he believes to the godly, and to defend it against the ungodly."

Reply Obj. 3: The gifts are more perfect than the moral and intellectual virtues; but they are not more perfect than the theological virtues; rather are all the gifts ordained to the perfection of the theological virtues, as to their end. Hence it is not unreasonable if several gifts are ordained to one theological virtue.
Q: Objection 1: It would seem that knowledge is not a gift. For the gifts of the Holy Ghost surpass the natural faculty. But knowledge implies an effect of natural reason: for the Philosopher says (Poster. i, 2) that a "demonstration is a syllogism which produces knowledge." Therefore knowledge is not a gift of the Holy Ghost.

Obj. 2: Further, the gifts of the Holy Ghost are common to all holy persons, as stated above (Q. 8, A. 4; I-II, Q. 68, A. 5). Now Augustine says (De Trin. xiv, 1) that "many of the faithful lack knowledge though they have faith." Therefore knowledge is not a gift.

Obj. 3: Further, the gifts are more perfect than the virtues, as stated above (I-II, Q. 68, A. 8). Therefore one gift suffices for the perfection of one virtue. Now the gift of understanding responds to the virtue of faith, as stated above (Q. 8, A. 2). Therefore the gift of knowledge does not respond to that virtue, nor does it appear to which other virtue it can respond. Since, then, the gifts are perfections of virtues, as stated above (I-II, Q. 68, AA. 1, 2), it seems that knowledge is not a gift.
Q: Objection 1: It would seem that the gift of knowledge is about Divine things. For Augustine says (De Trin. xiv, 1) that "knowledge begets, nourishes and strengthens faith." Now faith is about Divine things, because its object is the First Truth, as stated above (Q. 1, A. 1). Therefore the gift of knowledge also is about Divine things.

Obj. 2: Further, the gift of knowledge is more excellent than acquired knowledge. But there is an acquired knowledge about Divine things, for instance, the science of metaphysics. Much more therefore is the gift of knowledge about Divine things.

Obj. 3: Further, according to Rom. 1:20, "the invisible things of God . . . are clearly seen, being understood by the things that are made." If therefore there is knowledge about created things, it seems that there is also knowledge of Divine things.
Q: Whether the Gift of Knowledge Is Practical Knowledge?

A: On the contrary,
Gregory says (Moral. i, 32): "Knowledge on her own day prepares a feast, because she overcomes the fast of ignorance in the mind." Now ignorance is not entirely removed, save by both kinds of knowledge, viz. speculative and practical. Therefore the gift of knowledge is both speculative and practical.

I answer that,
As stated above (Q. 9, A. 8), the gift of knowledge, like the gift of understanding, is ordained to the certitude of faith. Now faith consists primarily and principally in speculation, in as much as it is founded on the First Truth. But since the First Truth is also the last end for the sake of which our works are done, hence it is that faith extends to works, according to Gal. 5:6: "Faith . . . worketh by charity."

The consequence is that the gift of knowledge also, primarily and principally indeed, regards speculation, in so far as man knows what he ought to hold by faith; yet, secondarily, it extends to works, since we are directed in our actions by the knowledge of matters of faith, and of conclusions drawn therefrom.

Reply Obj. 1: Augustine is speaking of the gift of knowledge, in so far as it extends to works; for action is ascribed to knowledge, yet not action solely, nor primarily: and in this way it directs piety.

Hence the Reply to the Second Objection is clear.

Reply Obj. 3: As we have already stated (Q. 8, A. 5) about the gift of understanding, not everyone who understands, has the gift of understanding, but only he that understands through a habit of grace: and so we must take note, with regard to the gift of knowledge, that they alone have the gift of knowledge, who judge aright about matters of faith and action, through the grace bestowed on them, so as never to wander from the straight path of justice. This is the knowledge of holy things, according to Wis. 10:10: "She conducted the just . . . through the right ways . . . and gave him the knowledge of holy things."
Q: Objection 1: It would seem that the knowledge, which is numbered among the gifts, is practical knowledge. For Augustine says (De Trin. xii, 14) that "knowledge is concerned with the actions in which we make use of external things." But the knowledge which is concerned about actions is practical. Therefore the gift of knowledge is practical.

Obj. 2: Further, Gregory says (Moral. i, 32): "Knowledge is nought if it hath not its use for piety . . . and piety is very useless if it lacks the discernment of knowledge." Now it follows from this authority that knowledge directs piety. But this cannot apply to a speculative science. Therefore the gift of knowledge is not speculative but practical.

Obj. 3: Further, the gifts of the Holy Ghost are only in the righteous, as stated above (Q. 9, A. 5). But speculative knowledge can be also in the unrighteous, according to James 4:17: "To him . . . who knoweth to do good, and doth it not, to him it is a sin." Therefore the gift of knowledge is not speculative but practical.
Q: Objection 1: It would seem that the third beatitude, "Blessed are they that mourn," does not correspond to the gift of knowledge. For, even as evil is the cause of sorrow and grief, so is good the cause of joy. Now knowledge brings good to light rather than evil, since the latter is known through evil: for "the straight line rules both itself and the crooked line" (De Anima i, 5). Therefore the aforesaid beatitude does not suitably correspond to the gift of knowledge.

Obj. 2: Further, consideration of truth is an act of knowledge. Now there is no sorrow in the consideration of truth; rather is there joy, since it is written (Wis. 8:16): "Her conversation hath no bitterness, nor her company any tediousness, but joy and gladness." Therefore the aforesaid beatitude does not suitably correspond with the gift of knowledge.

Obj. 3: Further, the gift of knowledge consists in speculation, before operation. Now, in so far as it consists in speculation, sorrow does not correspond to it, since "the speculative intellect is not concerned about things to be sought or avoided" (De Anima iii, 9). Therefore the aforesaid beatitude is not suitably reckoned to correspond with the gift of knowledge.
Q: Whether Unbelief Is a Sin?

A: On the contrary,
Vice is opposed to virtue. Now faith is a virtue, and unbelief is opposed to it. Therefore unbelief is a sin.

I answer that,
Unbelief may be taken in two ways: first, by way of pure negation, so that a man be called an unbeliever, merely because he has not the faith. Secondly, unbelief may be taken by way of opposition to the faith; in which sense a man refuses to hear the faith, or despises it, according to Isa. 53:1: "Who hath believed our report?" It is this that completes the notion of unbelief, and it is in this sense that unbelief is a sin.

If, however, we take it by way of pure negation, as we find it in those who have heard nothing about the faith, it bears the character, not of sin, but of punishment, because such like ignorance of Divine things is a result of the sin of our first parent. If such like unbelievers are damned, it is on account of other sins, which cannot be taken away without faith, but not on account of their sin of unbelief. Hence Our Lord said (John 15:22) "If I had not come, and spoken to them, they would not have sin"; which Augustine expounds (Tract. lxxxix in Joan.) as "referring to the sin whereby they believed not in Christ."

Reply Obj. 1: To have the faith is not part of human nature, but it is part of human nature that man's mind should not thwart his inner instinct, and the outward preaching of the truth. Hence, in this way, unbelief is contrary to nature.

Reply Obj. 2: This argument takes unbelief as denoting a pure negation.

Reply Obj. 3: Unbelief, in so far as it is a sin, arises from pride, through which man is unwilling to subject his intellect to the rules of faith, and to the sound interpretation of the Fathers. Hence Gregory says (Moral. xxxi, 45) that "presumptuous innovations arise from vainglory."

It might also be replied that just as the theological virtues are not reduced to the cardinal virtues, but precede them, so too, the vices opposed to the theological virtues are not reduced to the capital vices.
Q: Objection 1: It would seem that unbelief is not a sin. For every sin is contrary to nature, as Damascene proves (De Fide Orth. ii, 4). Now unbelief seems not to be contrary to nature; for Augustine says (De Praedest. Sanct. v) that "to be capable to having faith, just as to be capable of having charity, is natural to all men; whereas to have faith, even as to have charity, belongs to the grace of the faithful." Therefore not to have faith, which is to be an unbeliever, is not a sin.

Obj. 2: Further, no one sins that which he cannot avoid, since every sin is voluntary. Now it is not in a man's power to avoid unbelief, for he cannot avoid it unless he have faith, because the Apostle says (Rom. 10:14): "How shall they believe in Him, of Whom they have not heard? And how shall they hear without a preacher?" Therefore unbelief does not seem to be a sin.

Obj. 3: Further, as stated above (I-II, Q. 84, A. 4), there are seven capital sins, to which all sins are reduced. But unbelief does not seem to be comprised under any of them. Therefore unbelief is not a sin.
Q: Whether Unbelief Is in the Intellect As Its Subject?

A: On the contrary,
Things which are contrary to one another are in the same subject. Now faith, to which unbelief is opposed, resides in the intellect. Therefore unbelief also is in the intellect.

I answer that,
As stated above (I-II, Q. 74, AA. 1, 2), sin is said to be in the power which is the principle of the sinful act. Now a sinful act may have two principles: one is its first and universal principle, which commands all acts of sin; and this is the will, because every sin is voluntary. The other principle of the sinful act is the proper and proximate principle which elicits the sinful act: thus the concupiscible is the principle of gluttony and lust, wherefore these sins are said to be in the concupiscible. Now dissent, which is the act proper to unbelief, is an act of the intellect, moved, however, by the will, just as assent is.

Therefore unbelief, like faith, is in the intellect as its proximate subject. But it is in the will as its first moving principle, in which way every sin is said to be in the will.

Hence the Reply to the First Objection is clear.

Reply Obj. 2: The will's contempt causes the intellect's dissent, which completes the notion of unbelief. Hence the cause of unbelief is in the will, while unbelief itself is in the intellect.

Reply Obj. 3: He that believes a wicked angel to be a good one, does not dissent from a matter of faith, because "his bodily senses are deceived, while his mind does not depart from a true and right judgment" as the gloss observes [*Augustine, Enchiridion lx]. But, according to the same authority, to adhere to Satan when he begins to invite one to his abode, i.e. wickedness and error, is not without sin.
Q: Objection 1: It would seem that unbelief is not in the intellect as its subject. For every sin is in the will, according to Augustine (De Duabus Anim. x, xi). Now unbelief is a sin, as stated above (A. 1). Therefore unbelief resides in the will and not in the intellect.

Obj. 2: Further, unbelief is sinful through contempt of the preaching of the faith. But contempt pertains to the will. Therefore unbelief is in the will.

Obj. 3: Further, a gloss [*Augustine, Enchiridion lx.] on 2 Cor. 11:14 "Satan . . . transformeth himself into an angel of light," says that if "a wicked angel pretend to be a good angel, and be taken for a good angel, it is not a dangerous or an unhealthy error, if he does or says what is becoming to a good angel." This seems to be because of the rectitude of the will of the man who adheres to the angel, since his intention is to adhere to a good angel. Therefore the sin of unbelief seems to consist entirely in a perverse will: and, consequently, it does not reside in the intellect.
Q: Whether Unbelief Is the Greatest of Sins?

A: On the contrary,
Augustine, commenting on John 15:22, "If I had not come, and spoken to them, they would not have sin," says (Tract. lxxxix in Joan.): "Under the general name, He refers to a singularly great sin. For this," viz. infidelity, "is the sin to which all others may be traced." Therefore unbelief is the greatest of sins.

I answer that,
Every sin consists formally in aversion from God, as stated above (I-II, Q. 71, A. 6; I-II, Q. 73, A. 3). Hence the more a sin severs man from God, the graver it is. Now man is more than ever separated from God by unbelief, because he has not even true knowledge of God: and by false knowledge of God, man does not approach Him, but is severed from Him.

Nor is it possible for one who has a false opinion of God, to know Him in any way at all, because the object of his opinion is not God. Therefore it is clear that the sin of unbelief is greater than any sin that occurs in the perversion of morals. This does not apply to the sins that are opposed to the theological virtues, as we shall state further on (Q. 20, A. 3; Q. 34, A. 2, ad 2; Q. 39, A. 2, ad 3).

Reply Obj. 1: Nothing hinders a sin that is more grave in its genus from being less grave in respect of some circumstances. Hence Augustine hesitated to decide between a bad Catholic, and a heretic not sinning otherwise, because although the heretic's sin is more grave generically, it can be lessened by a circumstance, and conversely the sin of the Catholic can, by some circumstance, be aggravated.

Reply Obj. 2: Unbelief includes both ignorance, as an accessory thereto, and resistance to matters of faith, and in the latter respect it is a most grave sin. In respect, however, of this ignorance, it has a certain reason for excuse, especially when a man sins not from malice, as was the case with the Apostle.

Reply Obj. 3: An unbeliever is more severely punished for his sin of unbelief than another sinner is for any sin whatever, if we consider the kind of sin. But in the case of another sin, e.g. adultery, committed by a believer, and by an unbeliever, the believer, other things being equal, sins more gravely than the unbeliever, both on account of his knowledge of the truth through faith, and on account of the sacraments of faith with which he has been satiated, and which he insults by committing sin.
Q: Objection 1: It would seem that unbelief is not the greatest of sins. For Augustine says (De Bapt. contra Donat. iv, 20): "I should hesitate to decide whether a very wicked Catholic ought to be preferred to a heretic, in whose life one finds nothing reprehensible beyond the fact that he is a heretic." But a heretic is an unbeliever. Therefore we ought not to say absolutely that unbelief is the greatest of sins.

Obj. 2: Further, that which diminishes or excuses a sin is not, seemingly, the greatest of sins. Now unbelief excuses or diminishes sin: for the Apostle says (1 Tim. 1:12, 13): "I . . . before was a blasphemer, and a persecutor and contumelious; but I obtained . . . mercy . . . because I did it ignorantly in unbelief." Therefore unbelief is not the greatest of sins.

Obj. 3: Further, the greater sin deserves the greater punishment, according to Deut. 25:2: "According to the measure of the sin shall the measure also of the stripes be." Now a greater punishment is due to believers than to unbelievers, according to Heb. 10:29: "How much more, do you think, he deserveth worse punishments, who hath trodden under foot the Son of God, and hath esteemed the blood of the testament unclean, by which he was sanctified?" Therefore unbelief is not the greatest of sins.
