6. It is not right for you to be proud! You know the saying, “A little bit of yeast makes the whole batch of dough rise.”
7. You must remove the old yeast of sin so that you will be entirely pure. Then you will be like a new batch of dough without any yeast, as indeed I know you actually are. For our Passover Festival is ready, now that Christ, our Passover lamb, has been sacrificed.
8. Let us celebrate our Passover, then, not with bread having the old yeast of sin and wickedness, but with the bread that has no yeast, the bread of purity and truth.
9. In the letter that I wrote you I told you not to associate with immoral people.
10. Now I did not mean pagans who are immoral or greedy or are thieves or who worship idols. To avoid them you would have to get out of the world completely.
11. What I meant was that you should not associate with a person who calls himself a believer but is immoral or greedy or worships idols or is a slanderer or a drunkard or a thief. Don't even sit down to eat with such a person.
12-13. After all, it is none of my business to judge outsiders. God will judge them. But should you not judge the members of your own fellowship? As the scripture says, “Remove the evil person from your group.”
