On the Holy Trinity

¹² We behold, then, by the sight of the mind, in that eternal truth from which all things temporal are made, the form according to which we are, and according to which we do anything by true and right reason, either in ourselves, or in things corporeal; and we have the true knowledge of things, thence conceived, as it were as a word within us, and by speaking we beget it from within; nor by being born does it depart from us. And when we speak to others, we apply to the word, remaining within us, the ministry of the voice or of some bodily sign, that by some kind of sensible remembrance some similar thing may be wrought also in the mind of him that hears—similar, I say, to that which does not depart from the mind of him that speaks. We do nothing, therefore, through the members of the body in our words and actions, by which the behavior of men is either approved or blamed, which we do not anticipate by a word uttered within ourselves. For no one willingly does anything, which he has not first said in his heart.

13. And this word is conceived by love, either of the creature or of the Creator, that is, either of changeable nature or of unchangeable truth.
