Miscellanies 7.11.62

Using created things, then, when reason chooses and as far as it chooses, with thanksgiving to the Creator, he becomes master of his enjoyment too. He never bears a grudge and is never angry with anyone, even if someone deserves hatred for what he does; for he reveres the Maker and loves the one who shares his life, pitying him and praying for him because of his ignorance. He does indeed share the feelings of the body, bound as he is to a body that by nature can suffer, but he is not primarily affected by the passion. At any rate, in circumstances he did not choose, lifting himself from his troubles to what is his own, he is not carried away with what is foreign to him, but goes along with the body's necessities only so far as the soul is kept unharmed. For he wishes to be faithful not in reputation or in appearance, but in knowledge and truth, that is, in firm deed and effective word. So he not only praises what is good but also strives to be good himself, passing through love from “good and faithful servant” to “friend,” through the perfection of his disposition, which he has acquired purely through true learning and much discipline.
