Context

“"And Jesus, being full of the Holy Ghost, returned from the Jordan, and was led by the Spirit into the desert." Hence it is manifest that in Christ the gifts were in a pre-eminent degree. Reply Obj. 1: What is perfect in the order of its nature needs to be helped by something of a higher nature; as man, however perfect, needs to be helped by God. And in this way the virtues, which perfect the powers of the soul, as they are controlled by reason, no matter how perfect they are, need to be helped by the gifts, which perfect the soul's powers, inasmuch as these are moved by the Holy Ghost.” source
