Apostolic Constitutions, on 2Tim 2:19

“But the sure foundation of God standeth firm, having this seal: the Lord knoweth who are his; and let every one depart from iniquity who nameth the name of the Lord.”

“Wherefore, O bishop, when you are to go to prayer after the lessons, and the psalmody, and the instruction out of the Scriptures, let the deacon stand nigh you, and with a loud voice say: Let none have any quarrel with another; let none come in hypocrisy; that if there be any controversy found among any of you, they may be affected in conscience, and may pray to God, and be reconciled to their brethren. For if, upon coming into any one's house, we are to say, "Peace be to this house," like sons of peace bestowing peace on those who are worthy, as it is written, "He came and preached peace to you that are nigh, and them that are far off, whom the Lord knows to be His," much more is it incumbent on those that enter into the Church of God before all things to pray for the peace of God. But if he prays for it upon others, much more let himself be within the same, as a child of light; for he that has it not within himself is not fit to bestow it upon others.”
