Your hero was no saint, just as certain popes were not; far from it. He promoted the murder of Jews based on false statements. In a book entitled On Jews and Their Lies, Luther wrote:
“My advice, as I said earlier, is: First, that their synagogues be burned down, and that all who are able toss sulphur and pitch; it would be good if someone could also throw in some hellfire…Second, that all their books-- their prayer books, their Talmudic writings, also the entire Bible-- be taken from them, not leaving them one leaf, and that these be preserved for those who may be converted…Third, that they be forbidden on pain of death to praise God, to give thanks, to pray, and to teach publicly among us and in our country…Fourth, that they be forbidden to utter the name of God within our hearing. For we cannot with a good conscience listen to this or tolerate it…The rulers must act like a good physician who, when gangrene has set in proceeds without mercy to cut, saw, and burn flesh, veins, bone, and marrow. Such a procedure must also be followed in this instance. Burn down their synagogues, forbid all that I enumerated earlier, force them to work, and deal harshly with them. If this does not help we must drive them out like mad dogs."
