In Matthew 18:15-20, Jesus was teaching about unity in the body of Christ. He said if a brother has transgressed against you, go to him and show him what he did. If he shall hear you, you have gained your brother. If he will not listen, then take one or two witnesses to talk to him. Let all things be confirmed by two or three witnesses. If he still will not listen, bring him before the church and explain. If he still will not listen, let him be as a heathen or outcast. God is concerned with unity in the body of Christ. Anyone or thing that is disruptive must be dealt with to maintain unity in the body of Christ. Jesus said that where two or three are gathered in my name, I am there.
