Bump to 9,318 and a hefty clarification for the oft-misquoted Luther by our RC friends...
Third, they cloak their frightful and revolting sins with the gospel, call themselves Christian brethren, swear allegiance, and compel people to join them in such abominations. Thereby they become the greatest blasphemers and violators of God's holy name, and serve and honor the devil under the semblance of the gospel, so that they have ten times deserved death of body and soul, for never have I heard of uglier sins.Not quite sure, but I believe he's referring to Anabaptist here, they disagreed with Luther's view - er scripture- on baptism. Definitely peasants who thought Luther had not reformed enough. Earlier in the same piece, Luther recommends:
Therefore, whosoever can, should smite, strangle, and stab, secretly or publicly, and should remember that there is nothing more poisonous, pernicious, and devilish than a rebellious man.
