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.

_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.
