Whether it is lawful to be angry?

❌ Objection 1 : It would seem that it cannot be lawful to be angry. For Jerome in his exposition on Mt. 5:22, "Whosoever is angry with his brother," etc. says: "Some codices add 'without cause.' However, in the genuine codices the sentence is unqualified, and anger is forbidden altogether." Therefore it is nowise lawful to be angry.

❌ Objection 2 : Further, according to Dionysius (Div. Nom. iv) "The soul's evil is to be without reason." Now anger is always without reason: for the Philosopher says (Ethic. vii, 6) that "anger does not listen perfectly to reason"; and Gregory says (Moral. v, 45) that "when anger sunders the tranquil surface of the soul, it mangles and rends it by its riot"; and Cassian says (De Inst. Caenob. viii, 6): "From whatever cause it arises, the angry passion boils over and blinds the eye of the mind." Therefore it is always evil to be angry.

❌ Objection 3 : Further, anger is "desire for vengeance" [*Aristotle, Rhet. ii, 2] according to a gloss on Lev. 19:17, "Thou shalt not hate thy brother in thy heart." Now it would seem unlawful to desire vengeance, since this should be left to God, according to Dt. 32:35, "Revenge is Mine." Therefore it would seem that to be angry is always an evil.

❌ Objection 4 : Further, all that makes us depart from likeness to God is evil. Now anger always makes us depart from likeness to God, since God judges with tranquillity according to Wis. 12:18. Therefore to be angry is always an evil.
