3.

I omit many proofs which I might give from Scripture, that I may not make this letter longer than is needful; and I leave many more things to be considered by yourself in the light of your own learning. But I beseech you mark this, which is quite enough to decide the whole question: If so many transgressors in the one nation, which was then the Church of God, did not make those who were associated with them to be guilty like themselves; if that multitude of false brethren did not make the Apostle Paul, who was a member of the same Church with them, a seeker not of the things of Jesus Christ, but of his own,--it is manifest that a man is not made wicked by the wickedness of any one with whom he goes to the altar of Christ, even though he be not unknown to him, provided only that he do not encourage him in his wickedness, but by a good conscience disallowing his conduct keep himself apart from him. It is therefore obvious that, to be art and part with a thief, one must either help him in the theft, or receive with approbation what he has stolen. This I say in order to remove out of the way endless and unnecessary questions concerning the conduct of men, which are wholly irrelevant when advanced against our position.
