Apostolic Constitutions, Book II 15
1Observe, you who are our beloved sons, how merciful yet righteous the Lord our God is; how gracious and kind to men; and yet most certainly He will not acquit the guilty: though He welcomes the returning sinner, and revives him, leaving no room for suspicion to such as wish to judge sternly and to reject offenders entirely, and to refuse to vouchsafe to them exhortations which might bring them to repentance. In contradiction to such, God by Isaiah says to the bishops: Comfort, comfort my people, you priests: speak comfortably to Jerusalem. It therefore behooves you, upon hearing those words of His, to encourage those who have offended, and lead them to repentance, and afford them hope, and not vainly to suppose that you shall be partakers of their offenses on account of such your love to them. Receive the penitent with alacrity, and rejoice over them, and with mercy and bowels of compassion judge the sinners. For if a person was walking by the side of a river, and ready to stumble, and you should push him and thrust him into the river, instead of offering him your hand for his assistance, you would be guilty of the murder of your brother; whereas you ought rather to lend your helping hand as he was ready to fall, lest he perish without remedy, that both the people may take warning, and the offender may not utterly perish. It is your duty, O bishop, neither to overlook the sins of the people, nor to reject those who are penitent, that you may not unskilfully destroy the Lord's flock, or dishonour His new name, which is imposed on His people, and you yourself beest reproached as those ancient pastors were, of whom God speaks thus to Jeremiah: Many shepherds have destroyed my vineyard; they have polluted my heritage. And in another passage: My anger is growing hot against the shepherds, and against the lambs shall I have indignation. And elsewhere: You are the priests that dishonour my name.
