Summa Theologica Part III (Secunda Secundae) Part 7

Obj. 5: Further, evidence manifests the truth of the matter for which it is adduced. Now a thing is said to be apparent when its truth is already manifest. Therefore it seems to imply a contradiction to speak of "evidence of things that appear not": and so faith is unfittingly defined.

_On the contrary,_ The authority of the Apostle suffices.

_I answer that,_ Though some say that the above words of the Apostle are not a definition of faith, yet if we consider the matter aright, this definition overlooks none of the points in reference to which faith can be defined, albeit the words themselves are not arranged in the form of a definition, just as the philosophers touch on the principles of the syllogism, without employing the syllogistic form.

In order to make this clear, we must observe that since habits are known by their acts, and acts by their objects, faith, being a habit, should be defined by its proper act in relation to its proper object.

Now the act of faith is to believe, as stated above (Q. 2, AA. 2, 3), which is an act of the intellect determinate to one object of the will's command. Hence an act of faith is related both to the object of the will, i.e. to the good and the end, and to the object of the intellect, i.e. to the true. And since faith, through being a theological virtue, as stated above (I-II, Q. 62, A. 2), has one same thing for object and end, its object and end must, of necessity, be in proportion to one another. Now it has been already stated (Q. 1, AA. 1, 4) that the object of faith is the First Truth, as unseen, and whatever we hold on account thereof: so that it must needs be under the aspect of something unseen that the First Truth is the end of the act of faith, which aspect is that of a thing hoped for, according to the Apostle (Rom. 8:25): "We hope for that which we see not": because to see the truth is to possess it. Now one hopes not for what one has already, but for what one has not, as stated above (I-II, Q. 67, A.

4). Accordingly the relation of the act of faith to its end which is the object of the will, is indicated by the words: "Faith is the substance of things to be hoped for." For we are wont to call by the name of substance, the first beginning of a thing, especially when the whole subsequent thing is virtually contained in the first beginning; for instance, we might say that the first self-evident principles are the substance of science, because, to wit, these principles are in us the first beginnings of science, the whole of which is itself contained in them virtually. In this way then faith is said to be the "substance of things to be hoped for," for the reason that in us the first beginning of things to be hoped for is brought about by the a.s.sent of faith, which contains virtually all things to be hoped for. Because we hope to be made happy through seeing the unveiled truth to which our faith cleaves, as was made evident when we were speaking of happiness (I-II, Q. 3, A. 8; I-II, Q. 4, A. 3).

The relationship of the act of faith to the object of the intellect, considered as the object of faith, is indicated by the words, "evidence of things that appear not," where "evidence" is taken for the result of evidence. For evidence induces the intellect to adhere to a truth, wherefore the firm adhesion of the intellect to the non-apparent truth of faith is called "evidence" here. Hence another reading has "conviction," because to wit, the intellect of the believer is convinced by Divine authority, so as to a.s.sent to what it sees not. Accordingly if anyone would reduce the foregoing words to the form of a definition, he may say that "faith is a habit of the mind, whereby eternal life is begun in us, making the intellect a.s.sent to what is non-apparent."

In this way faith is distinguished from all other things pertaining to the intellect. For when we describe it as "evidence," we distinguish it from opinion, suspicion, and doubt, which do not make the intellect adhere to anything firmly; when we go on to say, "of things that appear not," we distinguish it from science and understanding, the object of which is something apparent; and when we say that it is "the substance of things to be hoped for," we distinguish the virtue of faith from faith commonly so called, which has no reference to the beat.i.tude we hope for.

Whatever other definitions are given of faith, are explanations of this one given by the Apostle. For when Augustine says (Tract. xl in Joan.: QQ. Evang. ii, qu. 39) that "faith is a virtue whereby we believe what we do not see," and when Damascene says (De Fide Orth.

iv, 11) that "faith is an a.s.sent without research," and when others say that "faith is that certainty of the mind about absent things which surpa.s.ses opinion but falls short of science," these all amount to the same as the Apostle's words: "Evidence of things that appear not"; and when Dionysius says (Div. Nom. vii) that "faith is the solid foundation of the believer, establishing him in the truth, and showing forth the truth in him," comes to the same as "substance of things to be hoped for."

Reply Obj. 1: "Substance" here does not stand for the supreme genus condivided with the other genera, but for that likeness to substance which is found in each genus, inasmuch as the first thing in a genus contains the others virtually and is said to be the substance thereof.

Reply Obj. 2: Since faith pertains to the intellect as commanded by the will, it must needs be directed, as to its end, to the objects of those virtues which perfect the will, among which is hope, as we shall prove further on (Q. 18, A. 1). For this reason the definition of faith includes the object of hope.

Reply Obj. 3: Love may be of the seen and of the unseen, of the present and of the absent. Consequently a thing to be loved is not so adapted to faith, as a thing to be hoped for, since hope is always of the absent and the unseen.

Reply Obj. 4: "Substance" and "evidence" as included in the definition of faith, do not denote various genera of faith, nor different acts, but different relationships of one act to different objects, as is clear from what has been said.

Reply Obj. 5: Evidence taken from the proper principles of a thing, make[s] it apparent, whereas evidence taken from Divine authority does not make a thing apparent in itself, and such is the evidence referred to in the definition of faith.

SECOND ARTICLE [II-II, Q. 4, Art. 2]

Whether Faith Resides in the Intellect?

Objection 1: It would seem that faith does not reside in the intellect. For Augustine says (De Praedest. Sanct. v) that "faith resides in the believer's will." Now the will is a power distinct from the intellect. Therefore faith does not reside in the intellect.

Obj. 2: Further, the a.s.sent of faith to believe anything, proceeds from the will obeying G.o.d. Therefore it seems that faith owes all its praise to obedience. Now obedience is in the will. Therefore faith is in the will, and not in the intellect.

Obj. 3: Further, the intellect is either speculative or practical.

Now faith is not in the speculative intellect, since this is not concerned with things to be sought or avoided, as stated in _De Anima_ iii, 9, so that it is not a principle of operation, whereas "faith ... worketh by charity" (Gal. 5:6). Likewise, neither is it in the practical intellect, the object of which is some true, contingent thing, that can be made or done. For the object of faith is the Eternal Truth, as was shown above (Q. 1, A. 1). Therefore faith does not reside in the intellect.

_On the contrary,_ Faith is succeeded by the heavenly vision, according to 1 Cor. 13:12: "We see now through a gla.s.s in a dark manner; but then face to face." Now vision is in the intellect.

Therefore faith is likewise.

_I answer that,_ Since faith is a virtue, its act must needs be perfect. Now, for the perfection of an act proceeding from two active principles, each of these principles must be perfect: for it is not possible for a thing to be sawn well, unless the sawyer possess the art, and the saw be well fitted for sawing. Now, in a power of the soul, which is related to opposite objects, a disposition to act well is a habit, as stated above (I-II, Q. 49, A. 4, ad 1, 2, 3).

Wherefore an act that proceeds from two such powers must be perfected by a habit residing in each of them. Again, it has been stated above (Q. 2, AA. 1, 2) that to believe is an act of the intellect inasmuch as the will moves it to a.s.sent. And this act proceeds from the will and the intellect, both of which have a natural apt.i.tude to be perfected in this way. Consequently, if the act of faith is to be perfect, there needs to be a habit in the will as well as in the intellect: even as there needs to be the habit of prudence in the reason, besides the habit of temperance in the concupiscible faculty, in order that the act of that faculty be perfect. Now, to believe is immediately an act of the intellect, because the object of that act is "the true," which pertains properly to the intellect. Consequently faith, which is the proper principle of that act, must needs reside in the intellect.

Reply Obj. 1: Augustine takes faith for the act of faith, which is described as depending on the believer's will, in so far as his intellect a.s.sents to matters of faith at the command of the will.

Reply Obj. 2: Not only does the will need to be ready to obey but also the intellect needs to be well disposed to follow the command of the will, even as the concupiscible faculty needs to be well disposed in order to follow the command of reason; hence there needs to be a habit of virtue not only in the commanding will but also in the a.s.senting intellect.

Reply Obj. 3: Faith resides in the speculative intellect, as evidenced by its object. But since this object, which is the First Truth, is the end of all our desires and actions, as Augustine proves (De Trin. i, 8), it follows that faith worketh by charity just as "the speculative intellect becomes practical by extension" (De Anima iii, 10).

THIRD ARTICLE [II-II, Q. 4, Art. 3]

Whether Charity Is the Form of Faith?

Objection 1: It would seem that charity is not the form of faith.

For each thing derives its species from its form. When therefore two things are opposite members of a division, one cannot be the form of the other. Now faith and charity are stated to be opposite members of a division, as different species of virtue (1 Cor. 13:13). Therefore charity is not the form of faith.

Obj. 2: Further, a form and the thing of which it is the form are in one subject, since together they form one simply. Now faith is in the intellect, while charity is in the will. Therefore charity is not the form of faith.

Obj. 3: Further, the form of a thing is a principle thereof. Now obedience, rather than charity, seems to be the principle of believing, on the part of the will, according to Rom. 1:5: "For obedience to the faith in all nations." Therefore obedience rather than charity, is the form of faith.

_On the contrary,_ Each thing works through its form. Now faith works through charity. Therefore the love of charity is the form of faith.

_I answer that,_ As appears from what has been said above (I-II, Q.

1, A. 3; I-II, Q. 18, A. 6), voluntary acts take their species from their end which is the will's object. Now that which gives a thing its species, is after the manner of a form in natural things.

Wherefore the form of any voluntary act is, in a manner, the end to which that act is directed, both because it takes its species therefrom, and because the mode of an action should correspond proportionately to the end. Now it is evident from what has been said (A. 1), that the act of faith is directed to the object of the will, i.e. the good, as to its end: and this good which is the end of faith, viz. the Divine Good, is the proper object of charity.

Therefore charity is called the form of faith in so far as the act of faith is perfected and formed by charity.

Reply Obj. 1: Charity is called the form of faith because it quickens the act of faith. Now nothing hinders one act from being quickened by different habits, so as to be reduced to various species in a certain order, as stated above (I-II, Q. 18, AA. 6, 7; I-II, Q. 61, A. 2) when we were treating of human acts in general.

Reply Obj. 2: This objection is true of an intrinsic form. But it is not thus that charity is the form of faith, but in the sense that it quickens the act of faith, as explained above.

Reply Obj. 3: Even obedience, and hope likewise, and whatever other virtue might precede the act of faith, is quickened by charity, as we shall show further on (Q. 23, A. 8), and consequently charity is spoken of as the form of faith.

FOURTH ARTICLE [II-II, Q. 4, Art. 4]

Whether Lifeless Faith Can Become Living, or Living Faith, Lifeless?

Objection 1: It would seem that lifeless faith does not become living, or living faith lifeless. For, according to 1 Cor. 13:10, "when that which is perfect is come, that which is in part shall be done away." Now lifeless faith is imperfect in comparison with living faith. Therefore when living faith comes, lifeless faith is done away, so that they are not one identical habit.

Obj. 2: Further, a dead thing does not become a living thing. Now lifeless faith is dead, according to James 2:20: "Faith without works is dead." Therefore lifeless faith cannot become living.

Obj. 3: Further, G.o.d's grace, by its advent, has no less effect in a believer than in an unbeliever. Now by coming to an unbeliever it causes the habit of faith. Therefore when it comes to a believer, who hitherto had the habit of lifeless faith, it causes another habit of faith in him.

Obj. 4: Further, as Boethius says (In Categ. Arist. i), "accidents cannot be altered." Now faith is an accident. Therefore the same faith cannot be at one time living, and at another, lifeless.

_On the contrary,_ A gloss on the words, "Faith without works is dead"

(James 2:20) adds, "by which it lives once more." Therefore faith which was lifeless and without form hitherto, becomes formed and living.

_I answer that,_ There have been various opinions on this question.

For some [*William of Auxerre, Sum. Aur. III, iii, 15] have said that living and lifeless faith are distinct habits, but that when living faith comes, lifeless faith is done away, and that, in like manner, when a man sins mortally after having living faith, a new habit of lifeless faith is infused into him by G.o.d. But it seems unfitting that grace should deprive man of a gift of G.o.d by coming to him, and that a gift of G.o.d should be infused into man, on account of a mortal sin.

Consequently others [*Alexander of Hales, Sum. Theol. iii, 64] have said that living and lifeless faith are indeed distinct habits, but that, all the same, when living faith comes the habit of lifeless faith is not taken away, and that it remains together with the habit of living faith in the same subject. Yet again it seems unreasonable that the habit of lifeless faith should remain inactive in a person having living faith.

We must therefore hold differently that living and lifeless faith are one and the same habit. The reason is that a habit is differentiated by that which directly pertains to that habit. Now since faith is a perfection of the intellect, that pertains directly to faith, which pertains to the intellect. Again, what pertains to the will, does not pertain directly to faith, so as to be able to differentiate the habit of faith. But the distinction of living from lifeless faith is in respect of something pertaining to the will, i.e. charity, and not in respect of something pertaining to the intellect. Therefore living and lifeless faith are not distinct habits.
