1 Corinthians 5:11-15

But actually, I wrote to you not to associate with any so-called brother if he is a sexually immoral person, or a greedy person, or an idolater, or is verbally abusive, or habitually drunk, or a swindler—not even to eat with such a person.

For what business of mine is it to judge outsiders? Do you not judge those who are within the church?

But those who are outside, God judges. Remove the evil person from among yourselves.
