And they wrote these things by their hand: The apostles and elders and brothers send greeting to the brothers, from the nations in Antioch and Syria and Cilicia.
But now I have written to you not to associate intimately, if any man called a brother and is either a fornicator, or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner; with such a one not to eat.
Now we command you, brothers, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother who walks disorderly, and not after the teaching which he received from us.
Therefore if I come, I will remember his deeds which he does, ranting against us with evil words. And not content with these, neither does he himself receive the brothers. And he forbids those who would, and casts them out of the church.
