The Bible commands Christians: Quit mixing in company with anyone called a brother that is a fornicator or a greedy person or an idolater or a reviler or a drunkard or an extortioner, not even eating with such a man. 1 Corinthians 5:11.
Is this Bible law harsh and demeaning? When a hardened criminal is sent to prison for breaking the law, is that viewed as harsh or coldhearted?
No, because the public has the right to safeguard the peace and security of the community.
In effect, the criminal is disfellowshipped from law-abiding society during his prison term.
Similarly, the Christian congregation is justified in expelling unrepentant wrongdoers from their midst.
Why? Because the congregation must be a haven from immoral predators and other willful practicers of sin.
Realizing that one sinner can destroy much good, the apostle Paul commanded fellow believers: Remove the wicked man from among yourselves. 1 Corinthians 5:13
This action prevents the sinner from spreading corruption in the congregation, and it protects the congregation’s good name.
2 John 9:11
Everyone that pushes ahead and does not remain in the teaching of the Christ does not have God If anyone comes to you and does not bring this teaching, never receive him into your homes or say a greeting to him.
