while one cries I am Paul's disciple, and another, I am Apollo's, are ye not vicious?

When I formerly writ to you, not to keep company with the vicious:

I did not mean the vicious Gentiles, the misers, the raparees, or with idolaters; for then you must have gone out of the world.

but my meaning was, not to keep company with any christian known to be vicious, or covetous, or an idolater, or a railer, or a drunkard, or rapacious, no not even to eat with such a one.

be not deceived : "vicious conversation corrupts good morals."
