In the first place, there is a confession which is founded on the Scriptures, and it is this: when anybody committed a sin publicly or with other men’s knowledge, he was accused before the congregation. If he abandoned his sin, they interceded for him with God. But if he would not listen to the congregation [häuffen], he was cast out and excluded from the assembly, so that no one would have anything to do with him. And this confession is commanded by God in Matthew18:15, “If your brother sins against you (so that you and others are offended), go and tell him his fault, between you and him alone.”
We no longer have any trace of this kind of confession anymore; at this point the gospel is in abeyance. Anybody who was able to re-establish it would be doing a good work. Here is where you should have exerted yourselves and re-established this kind of confession, and let the other things go; for no one would have been offended by this and everything would have gone smoothly and quietly. It should be done in this way: When you see a usurer, adulterer, thief, or drunkard, you should go to him in secret, and admonish him to give up his sin. If he will not listen, you should take two others with you and admonish him once more, in a brotherly way, to give up his sin. But if he scorns that, you should tell the pastor before the whole congregation, have your witnesses with you, and accuse him before the pastor in the presence of the people, saying: Dear pastor, this man has done this and that and would not take our brotherly admonition to give up his sin. Therefore I accuse him, together with my witnesses, who have heard this. Then, if he will not give up and willingly acknowledge his guilt, the pastor should exclude him and put him under the ban before the whole assembly, for the sake of the congregation, until he comes to himself and is received back again. This would be Christian. But I cannot undertake to carry it out single-handed.
