Part 1214
and consequently, the image of the Trinity may be considered as existing in the powers, and still more in the habits, forasmuch as the acts virtually exist therein.
* Reply to Objection 1: * Our being bears the image of God so far as if is proper to us, and excels that of the other animals, that is to say, in so far as we are endowed with a mind.

And by understanding I mean here that whereby we understand with actual thought; and by will, love, or dilectio
