Apostolic Constitutions, Book II 53

1But you who know who our God is, and what are His judgments, how can you bear to pass an unjust judgment, since your sentence will be immediately known to God? And if you have judged righteously, you will be deemed worthy of the recompenses of righteousness, both now and hereafter; but if unrighteously, you will partake of the like. We therefore advise you, brethren, rather to deserve commendation from God than rebukes; for the commendation of God is eternal life to men, as is His rebuke everlasting death. Be 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 you bring your gift to the altar, and there rememberest that your brother has anything against you, leave there your gift before the altar, and go your way; first be reconciled to your brother, and then come and offer your gift to God. Now the gift to God is every one's prayer and thanksgiving. If, therefore, you have anything against your brother, or he has anything against you, neither will your prayers be heard, nor will your thanksgivings be accepted, by reason of that hidden anger. But it is your duty, brethren, to pray continually. Yet, because God hears not those which are at enmity with their brethren by unjust quarrels, even though they should pray three times an hour, it is our duty to compose all our enmity and littleness of soul, that we may be able to pray with a pure and unpolluted heart. For the Lord commanded us to love even our enemies, and by no means to hate our friends. And the lawgiver says: You shall not hate any man; you shall not hate your brother in your mind. You shall certainly reprove your brother, and not incur sin on his account. You shall not hate an Egyptian, for you were a sojourner with him. You shall not hate an Idumæan, for he is your brother. And David says: If I have repaid those that requited me evil. Wherefore, if you will be a Christian, follow the law of the Lord: Loose every band of wickedness; for the Lord has given you authority to remit those sins to your brother which he has committed against you as far as seventy times seven, that is, four hundred and ninety times. How oft, therefore, have you remitted to your brother, that you are unwilling to do it now, when you also have heard Jeremiah saying, Do not any of you impute the wickedness of his neighbour in your hearts? But you remember injuries, and keepest enmity, and comest into judgment, and art suspicious of His anger, and your prayer is hindered. Nay, if you have remitted to your brother four hundred and ninety times, multiply your acts of gentleness still more, to do good for your own sake. Although he does not do so, yet, however, endeavour to forgive your brother for God's sake, that you may be the son of your Father which is in heaven, and when you pray, may be heard as a friend of God.
