I wrote unto you in an epistle not to company with fornicators:

8 Therefore let’s keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.
9 I wrote to you in my letter to have no company with sexual sinners;
10 yet not at all meaning with the sexual sinners of this world, or with the covetous and extortionists, or with idolaters, for then you would have to leave the world.
