What Does the Bible Say About Church Discipline?

God cares enough about our understanding and application of His truth to implement serious sanctions when we disobey it.

1Cor 5:5 - I have decided to deliver such a one to Satan for the destruction of his flesh.
1Cor 5:11 - I wrote you to not associate with any so-called brother if he is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler - not even to eat with such a one.
2Thess 3:6-15 - In the name of the Lord Jesus Christ, we command you, brothers, to keep away from every brother who is idle and does not live according to the teaching you received from us… If anyone does not obey our instruction in this letter, take special note of him. Do not associate with him, in order that he may feel ashamed. Yet do not regard him as an enemy, but warn him as a brother.
1Tim 1:20 - Among them are Hymenaeus and Alexander, whom I have handed over to Satan to be taught not to blaspheme.
1Tim 5:19-20 - Do not entertain an accusation against an elder unless it is brought by two or three witnesses. Those who sin are to be rebuked publicly, so that the others may take warning.
Titus 3:10-11 - Warn a divisive person once, and then warn him a second time. After that, have nothing to do with him. You may be sure that such a man is warped and sinful; he is self-condemned. Matt 18:17 - If he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
