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.
