Whether knowledge is a gift?

Objections

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.
Objection 2 : Further, the gifts of the Holy Ghost are common to all holy persons, as stated above (Question [8], Article [4]; FS, Question [68], Article [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.
Objection 3 : Further, the gifts are more perfect than the virtues, as stated above (FS, Question [68], Article [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 (Question [8], Article [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 (FS, Question [68], Articles [1],2), it seems that knowledge is not a gift.
