Callistus I of Rome

But if any one has fallen in anything, let us not consign him to ruin; but let us reprove him with brotherly affection, as the blessed apostle says: "If a man be overtaken in any fault, ye which are spiritual restore such an one in the spirit of meekness; considering thyself, test thou also be tempted. Bear ye one another's burden, and so will ye fulfil the law of Christ."
