Matthew 18:15-17
Restoring Christian Relationships
18:15 “If your brother sins, go and show him his fault when the two of you are alone. If he listens to you, you have regained your brother.
18:16 But if he does not listen, take one or two others with you, so that at the testimony of two or three witnesses every matter may be established.
18:17 If he refuses to listen to them, tell it to the church. If he refuses to listen to the church, treat him like a Gentile or a tax collector.
Matthew 23:8
23:8 But you are not to be called ‘Rabbi,’ for you have one Teacher and you are all brothers.
