Doctor Gratiae

Today was the feast of St. Augustine of Hippo, Doctor of the Church. From De Trinitate, Book XIV:

This trinity, then, of the mind is not therefore the image of God, because the mind remembers itself, and understands and loves itself; but because it can also remember, understand, and love Him by whom it was made. And in so doing it is made wise itself. But if it does not do so, even when it remembers, understands, and loves itself, then it is foolish. Let it then remember its God, after whose image it is made, and let it understand and love Him. Or to say the same thing more briefly, let it worship God, who is not made, by whom because itself was made, it is capable and can be partaker of Him; wherefore it is written, "Behold, the worship of God, that is wisdom." And then it will be wise, not by its own light, but by participation of that supreme Light; and wherein it is eternal, therein shall reign in blessedness. For this wisdom of man is so called, in that it is also of God. For then it is true wisdom; for if it is human, it is vain.
