1 Corinthians 5:9-11

New Catholic Bible

⁹ In my letter, I wrote to you not to associate with people who are leading immoral lives.^{[a] 10} Obviously, I was not referring to contact with people in the world who are immoral or with those who are greedy or thieves or worshipers of false gods, since to do this you would have to leave the world. ¹¹ What I really meant to get across was that you should not associate with any brother or sister who is sexually immoral, greedy, an idolater, a slanderer, a drunkard or a robber. You should not even eat with such a person.
