1 Corinthians 5:6-11

Boasting over your tolerance of sin is inappropriate. Don’t you understand that even a small compromise with sin permeates the entire fellowship, just as a little leaven permeates a batch of dough? So remove every trace of your “leaven” of compromise with sin so that you might become new and pure again. For indeed, you are clean because Christ, our Passover Lamb, has been sacrificed for us. So now we can celebrate our continual feast, not with the old “leaven,” the yeast of wickedness or bitterness, but we will feast on the freshly baked bread of innocence and holiness. 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.
