"If your brother or sister does something wrong to you, go and tell that person what he did wrong. Do this alone with that person. If that person listens to you, then you have helped that person to be your brother again.
But if that person refuses to listen, then go to him again and bring one or two people with you. Then there will be two or three other people that will be able to tell all that happened. F253
If that person refuses to listen to them, then tell the church (group of believers). If that person refuses to listen to the church, then treat him like he is a person that does not believe in God. Treat him like he is a tax collector. F254
"I tell you the truth. When you speak judgment here on earth, that judgment will be God's judgment. When you promise forgiveness here on earth, that forgiveness will be God's forgiveness. F255
"Also, I tell you that if two of you on earth agree about something, then you can pray for it. And the thing you ask for will be done for you by my Father in heaven.
