TSK · Acts 11:3

But the Pharisees and the experts in the law were complaining,“This man welcomes sinners and eats with them.”

He said to them,“You know that it is unlawful for a Jew to associate with or visit a Gentile, yet God has shown me that I should call no person defiled or ritually unclean.

But now I am writing to you not to associate with anyone who calls himself a Christian who is sexually immoral, or greedy, or an idolater, or verbally abusive, or a drunkard, or a swindler. Do not even eat with such a person.

If anyone comes to you and does not bring this teaching, do not receive him into your house and do not give him any greeting,
