FIFTH ARTICLE [II-II, Q. 4, Art. 5]

Whether Faith Is a Virtue?

Objection 1: It would seem that faith is not a virtue. For virtue

is directed to the good, since "it is virtue that makes its subject

good," as the Philosopher states (Ethic. ii, 6). But faith is

directed to the true. Therefore faith is not a virtue.

Obj. 2: Further, infused virtue is more perfect than acquired virtue.

Now faith, on account of its imperfection, is not placed among the

acquired intellectual virtues, as the Philosopher states (Ethic. vi,

3). Much less, therefore, can it be considered an infused virtue.

Obj. 3: Further, living and lifeless faith are the same species, as

stated above (A. 4). Now lifeless faith is not a virtue, since it is

not connected with the other virtues. Therefore neither is living

faith a virtue.

Obj. 4: Further, the gratuitous graces and the fruits are distinct

from the virtues. But faith is numbered among the gratuitous graces

(1 Cor. 12:9) and likewise among the fruits (Gal. 5:23). Therefore

faith is not a virtue.

_On the contrary,_ Man is justified by the virtues, since "justice

is all virtue," as the Philosopher states (Ethic. v, 1). Now man is

justified by faith according to Rom. 5:1: "Being justified therefore

by faith let us have peace," etc. Therefore faith is a virtue.

_I answer that,_ As shown above, it is by human virtue that human

acts are rendered good; hence, any habit that is always the principle

of a good act, may be called a human virtue. Such a habit is living

faith. For since to believe is an act of the intellect assenting to

the truth at the command of the will, two things are required that

this act may be perfect: one of which is that the intellect should

infallibly tend to its object, which is the true; while the other is

that the will should be infallibly directed to the last end, on

account of which it assents to the true: and both of these are to be

found in the act of living faith. For it belongs to the very essence

of faith that the intellect should ever tend to the true, since

nothing false can be the object of faith, as proved above (Q. 1, A.

3): while the effect of charity, which is the form of faith, is that

the soul ever has its will directed to a good end. Therefore living

faith is a virtue.

On the other hand, lifeless faith is not a virtue, because, though

the act of lifeless faith is duly perfect on the part of the

intellect, it has not its due perfection as regards the will: just as

if temperance be in the concupiscible, without prudence being in the

rational part, temperance is not a virtue, as stated above (I-II, Q.

65, A. 1), because the act of temperance requires both an act of

reason, and an act of the concupiscible faculty, even as the act of

faith requires an act of the will, and an act of the intellect.

Reply Obj. 1: The truth is itself the good of the intellect, since it

is its perfection: and consequently faith has a relation to some good

in so far as it directs the intellect to the true. Furthermore, it

has a relation to the good considered as the object of the will,

inasmuch as it is formed by charity.

Reply Obj. 2: The faith of which the Philosopher speaks is based on

human reasoning in a conclusion which does not follow, of necessity,

from its premisses; and which is subject to be false: hence such like

faith is not a virtue. On the other hand, the faith of which we are

speaking is based on the Divine Truth, which is infallible, and

consequently its object cannot be anything false; so that faith of

this kind can be a virtue.

Reply Obj. 3: Living and lifeless faith do not differ specifically,

as though they belonged to different species. But they differ as

perfect and imperfect within the same species. Hence lifeless faith,

being imperfect, does not satisfy the conditions of a perfect virtue,

for "virtue is a kind of perfection" (Phys. vii, text. 18).

Reply Obj. 4: Some say that faith which is numbered among the

gratuitous graces is lifeless faith. But this is said without reason,

since the gratuitous graces, which are mentioned in that passage, are

not common to all the members of the Church: wherefore the Apostle

says: "There are diversities of graces," and again, "To one is given"

this grace and "to another" that. Now lifeless faith is common to all

members of the Church, because its lifelessness is not part of its

substance, if we consider it as a gratuitous gift. We must,

therefore, say that in that passage, faith denotes a certain

excellency of faith, for instance, "constancy in faith," according

to a gloss, or the "word of faith."

Faith is numbered among the fruits, in so far as it gives a certain

pleasure in its act by reason of its certainty, wherefore the gloss

on the fifth chapter to the Galatians, where the fruits are

enumerated, explains faith as being "certainty about the unseen."
