When is it justified to angry?
A brother asked Abba Poemen: What does it mean to get angry at one’s brother without cause? And he replied: When your brother attacks you, whatever the insults are, if you get angry at him, you are getting angry without cause. Even if he were to pull out your right eye, and to cut off your right hand, if you get angry at him, you are getting angry without cause. Yet if he were to try to take you away from God, then get angry!
