4. Therefore ought we to rebuke in love; not with any eager desire to injure, but with an earnest care to amend. If we be so minded, most excellently do we practise that which we have been recommended to-day; “If thy brother shall sin against thee, rebuke him between thee and him alone.” Why dost thou rebuke him? Because thou art grieved, that he should have sinned against thee? God forbid. If from love of thyself thou do it, thou doest nothing. If from love to him thou do it, thou doest excellently. In fact, observe in these words themselves, for the love of whom thou oughtest to do it, whether of thyself or him. “If he shall hear thee, thou hast gained thy brother.” Do it for his sake then, that thou mayest “gain” him. If by so doing thou “gain” him, hadst thou not done it, he would have been lost. How is it then that most men disregard these sins, and say, “What great thing have I done? I have only sinned against man.” Disregard them not. Thou hast sinned against man; but wouldest thou know that in sinning against man thou art lost. If he, against whom thou hast sinned, have “rebuked thee between thee and him alone,” and thou hast listened to him, he hath “gained” thee. What can “hath gained thee,” mean; but that thou hadst been lost, if he had not gained thee. For if thou wouldest not have been lost, how hath he gained thee? Let no man then disregard it, when he sins against a brother. For the Apostle saith in a certain place, “But when ye sin so against the brethren, and wound their weak conscience, ye sin against Christ;” for this reason, because we have been all made members of Christ. How dost thou not sin against Christ, who sinnest against a member of Christ?
