1 Corinthians 5:9-13

I wrote you in my previous letter asking you not to associate with those who practice sexual immorality. Yet in no way was I referring to avoiding contact with unbelievers who are immoral, or greedy, or swindlers, or those who worship other gods—for that would mean you’d have to isolate yourself from the world entirely! But now I’m writing to you so that you would exclude from your fellowship anyone who calls himself a fellow believer and practices sexual immorality, or is consumed with greed, or is an idolater, or is verbally abusive or a drunkard or a swindler. Don’t mingle with them or even have a meal with someone like that. What right do I have to pronounce judgment on unbelievers? That’s God’s responsibility. But those who are inside the church family are our responsibility to discern and judge. So it’s your duty to remove that wicked one from among you.
