Matthew 18:15-18

“If your fellow believer sins against you, you must go to that one privately and attempt to resolve the matter. If he responds, your relationship is restored. But if his heart is closed to you, then go to him again, taking one or two others with you. You’ll be fulfilling what the Scripture teaches when it says, ‘Every word may be verified by the testimony of two or three witnesses.’ And if he refuses to listen, then share the issue with the congregation in hopes of restoration. If he still refuses to respond, even to the church, then you must disregard him as though he were an outsider, on the same level as an unrepentant sinner. “Receive this truth: Whatever you forbid on earth will be considered to be forbidden in heaven, and whatever you release on earth will be considered to be released in heaven.
