He who is angry without cause shall be judged; but he who is angry with cause shall not be judged. For if there were no anger, neither teaching would profit, nor judgments hold, nor crimes be controlled. So that he who on just cause is not angry, is in sin; for an unreasonable patience sows vices, breeds carelessness, and invites the good as well as the bad to do evil.
