matthew 18:15 Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. - Free Bible Online

      15. Moreover, if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother, &c.--Probably our Lord had reference still to the late dispute, Who should be the greatest? After the rebuke--so gentle and captivating, yet so dignified and divine--under which they would doubtless be smarting, perhaps each would be saying, It was not I that began it, it was not I that threw out unworthy and irritating insinuations against my brethren. Be it so, says our Lord; but as such things will often arise, I will direct you how to proceed. First, Neither harbor a grudge against your offending brother, nor break forth upon him in presence of the unbelieving; but take him aside, show him his fault, and if he own and make reparation for it, you have done more service to him than even justice to yourself. Next, If this fail, take two or three to witness how just your complaint is, and how brotherly your spirit in dealing with him. Again, If this fail, bring him before the Church or congregation to which both belong. Lastly, If even this fail, regard him as no longer a brother Christian, but as one "without"--as the Jews did Gentiles and publicans.
