15 "If another believer sins against you, go privately and point out the offense. If the other person listens and confesses it, you have won that person back. 16 But if you are unsuccessful, take one or two others with you and go back again, so that everything you say may be confirmed by two or three witnesses. 17 If the person still refuses to listen, take your case to the church. Then if he or she won't accept the church's decision, treat that person as a pagan or a corrupt tax collector. 18 "I tell you the truth, whatever you forbid on earth will be forbidden in heaven, and whatever you permit on earth will be permitted in heaven.

Commentary on Matthew 18:15-20
(Read Matthew 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.
