I wrote to you in my letter not to associate with sexually immoral persons— not at all meaning the immoral of this world, or the greedy and robbers, or idolaters, since you would then need to go out of the world. But now I am writing to you not to associate with anyone who bears the name of brother or sister who is sexually immoral or greedy, or is an idolater, reviler, drunkard, or robber. Do not even eat with such a one. For what have I to do with judging those outside? Is it not those who are inside that you are to judge? God will judge those outside. ‘Drive out the wicked person from among you.’ (1Corinthians 5: 9-13)

Earlier Paul counseled that we avoid judging and allow God to judge. Now he quotes from Deuteronomy's treatment of capital crimes in directing harsh judgment on a range of behavior.

Paul specifies six behaviors that should result in expulsion from the community of faith:

Pornos - Prostitution, especially a male prostitute, fornication.

Pleonektes - Greedy, covetous of others.

Eidololatres - worshipper of false gods.

Loidorus - mischief maker, reviler.

Muthusos - drunkard.

Harpax - extortioner, robber.

What each of these behaviors may share is a self-indulgence that dismisses or misuses one's relationship with others, including with God.

Trying to resolve the apparent contradiction, Paul's argument may be that we should be realistic when someone has already chosen to not be a member of the community.
