Do not say: “I cannot bear this from such a man, nor should I suffer things of this kind, for he has done me a great wrong. He has accused me of many things of which I never thought. However, from someone else I will gladly suffer as much as I think I should.” Such a thought is foolish, for it does not consider the virtue of patience or the One who will reward it, but rather weighs the person and the offense committed. The man who will suffer only as much as seems good to him, who will accept suffering only from those from whom he is pleased to accept it, is not truly patient.
