Matthew 18:15-18

18:15 “If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. 18:16 But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’ 18:17 If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector. 18:18 “Truly I tell you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.
