1 Corinthians 5:11

But as it is, I wrote unto you not to keep company, if any man that is named a brother be a fornicator, or covetous, or an idolater, or a reviler or a drunkard, or an extortioner; with such a one no, not to eat.

But as it is ... or "Now I write ..." as in the English Revised Version margin (1885).

I wrote unto you ... carries the meaning of "what I meant when I wrote to you."

The blanket rule laid down here requiring the Christian to forego any association with unfaithful Christians was stated thus by Russell:

Have no familiar intercourse with one that is named a brother but is false to his profession; withdraw from all associations indicating brotherhood. He does not mean that Christians should go out of the world; monastic seclusion is not for a moment contemplated.[20]
