(18) Whatsoever ye shall bind on earth.--(See Note on Matthew 16:19.) The promise before made to Peter is now extended not only to the other Apostles, but to the whole society of which they were the representatives, and is, of course, to be understood as dependent on the same implied, though not expressed, condition. So far as the Ecclesia was true to its Lord, and guided by His Spirit, it was not to think that its decisions depended on any temporal power. They were clothed, as truth and righteousness are ever clothed, with a divine authority. As connected with the treatment of individual offenders, the words "bind" and "loose" may seem here to approximate more closely than in Matthew 16:19, to "condemning" and "absolving" in their force, but there is no ground for setting aside, even here, their received meaning in the language of the scribes. The Christian had to apply general laws to particular instances. The trial of each offender became a ruling case. It was binding or loosing, directly as interpreting the Law, only secondarily and indirectly as punishing or pardoning.

Verse 18. - The following words are addressed, not, as the preceding verse, to the offended Christian, but to the apostles, as possessed of some superior powers above those of any individual congregation. Verily I say unto you. The Lord solemnly confers the grant made to Peter (Matthew 16:19) on the whole apostolate. The binding and loosing, in a restricted sense, and in logical connection with what precedes, refer to the confirmation and authorization of the sentence of the Ecclesia, which is not valid, so to speak, in the heavenly court till endorsed by Christ's representatives - the apostles. Whether the verdict was the excommunication of the offender ("bind") or his pardon and restoration ("loose"), the ratification of the apostles was required, and would be made good in heaven. The treatment of the incestuous Christian by St. Paul is a practical comment on this passage. The congregation decides on the man's guilt, but St. Paul "binds" him, retains his sins, and delivers him to Satan (1 Corinthians 5:1-5); and when on his repentance he is forgiven, it is the apostle who "looses" him, acting as the representative of Christ (2 Corinthians 2:10). In a general sense, the judicial and disciplinary powers of the Christian priesthood have been founded on this passage, which from early times has been used in the service of ordination. Each body of Christians has its own way of interpreting the promise. While some opine that, speaking in Christ's name and with his authority, the priest can pronounce or withhold pardon; others believe that external discipline is all that is intended; others again think that the terms are satisfied by the ministration of the Word and sacraments, as a physician gives health by prescribing remedies.

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.Verily I say unto you,.... To them all, what he had said before to Peter; See Gill on Matthew 16:19, what is said here, refers to things and not persons, as there also.
