Apostolic Constitutions, on Eph 4:26

“Be angry, and sin not. Let not the sun go down upon your anger.”

“Be ye therefore righteous judges, peacemakers, and without anger. For "he that is angry with his brother without a cause is obnoxious to the judgment." But if it happens that by any one's contrivance you are angry at anybody, "let not the sun go down upon your wrath; " for says David, "Be angry and sin not; " that is, be soon reconciled, lest your wrath continue so long that it turn to a settled hatred, and work sin. "For the souls of those that bear a settled hatred are to death," says Solomon. But our Lord and Saviour Jesus Christ says in the Gospels: "If thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee, leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift to God." Now the gift to God is every one's prayer and thanksgiving. If, therefore, thou hast anything against thy brother, or he has anything against thee, neither will thy prayers be heard, nor will thy thanksgivings be accepted, by reason of that hidden anger.”
