{5} Moreover if thy brother shall trespass against {e} thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother.

(5) We must strive for agreement, and not to revenge injuries.

(e) If his offence is such that only you know your brother's offence.

People's New Testament

18:15 If thy brother. Brother in the church. Compare Mr 9:38 Lu 9:49.

Sin against thee. Personally. Injure you or do you wrong.

Shew him his fault. Go to him privately and have a kind, brotherly talk over the matter, and try to show him his fault.

Gained thy brother. For thyself, by restoring good feeling; for God, by leading him to a sense of sin and repentance.

Wesley's Notes

18:15 But how can we avoid giving offence to some? or being offended at others! Especially suppose they are quite in the wrong? Suppose they commit a known sin? Our Lord here teaches us how: he lays down a sure method of avoiding all offences. Whosoever closely observes this threefold rule, will seldom offend others, and never be offended himself. If any do any thing amiss, of which thou art an eye or ear witness, thus saith the Lord, If thy brother - Any who is a member of the same religious community: Sin against thee, Go and reprove him alone - If it may be in person; if that cannot so well be done, by thy messenger; or in writing. Observe, our Lord gives no liberty to omit this; or to exchange it for either of the following steps. If this do not succeed, Take with thee one or two more - Men whom he esteems or loves, who may then confirm and enforce what thou sayest; and afterward, if need require, bear witness of what was spoken. If even this does not succeed, then, and not before, Tell it to the elders of the Church - Lay the whole matter open before those who watch over yours and his soul. If all this avail not, have no farther intercourse with him, only such as thou hast with heathens. Can any thing be plainer? Christ does here as expressly command all Christians who see a brother do evil, to take this way, not another, and to take these steps, in this order, as he does to honour their father and mother. But if so, in what land do the Christians live? If we proceed from the private carriage of man to man, to proceedings of a more public nature, in what Christian nation are Church censures conformed to this rule? Is this the form in which ecclesiastical judgments appear, in the popish, or even the Protestant world? Are these the methods used even by those who boast the most loudly of the authority of Christ to confirm their sentences? Let us earnestly pray, that this dishonour to the Christian name may be wiped away, and that common humanity may not, with such solemn mockery, be destroyed in the name of the Lord! Let him be to thee as the heathen - To whom thou still owest earnest good will, and all the offices of humanity. Luke 17:3.

Jamieson-Fausset-Brown Bible Commentary

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.

Matthew Henry's Concise Commentary

18:15-20 If a professed Christian is wronged by another, he ought not to complain of it to others, as is often done merely upon report, but to go to the offender privately, state the matter kindly, and show him his conduct. This would generally have all the desired effect with a true Christian, and the parties would be reconciled. The principles of these rules may be practised every where, and under all circumstances, though they are too much neglected by all. But how few try the method which Christ has expressly enjoined to all his disciples! In all our proceedings we should seek direction in prayer; we cannot too highly prize the promises of God. Wherever and whenever we meet in the name of Christ, we should consider him as present in the midst of us.
