But I wasn't talking about unbelievers who indulge in sexual sin, or who are greedy or are swindlers or idol worshipers. You would have to leave this world to avoid people like that.
What I meant was that you are not to associate with anyone who claims to be a Christian yet indulges in sexual sin, or is greedy, or worships idols, or is abusive, or a drunkard, or a swindler. Don't even eat with such people.
