I beg to differ. Luther was an anti-Semitist. We should repudiate his views. His views went much beyond a dislike for the Jewish faith. In fact, he makes some of the same arguments later used by Hitler: the Germans are kept down by the Jew!
From On the Jews and Their Lies:
Moreover, they are nothing but thieves and robbers who daily eat no morsel and wear no thread of clothing which they have not stolen and pilfered from us by means of their accursed usury. Thus they live from day to day, together with wife and child, by theft and robbery, as arch-thieves and robbers, in the most impenitent security"¦ Over and above that we let them get rich on our sweat and blood, while we remain poor and they such the marrow from our bones.
-Martin Luther (On the Jews and Their Lies)
...but then eject [the Jews] forever from this country. For, as we have heard, God's anger with them is so intense that gentle mercy will only tend to make them worse and worse, while sharp mercy will reform them but little. Therefore, in any case, away with them!
-Martin Luther (On the Jews and Their Lies)
In brief, dear princes and lords, those of you who have Jews under your rule-- if my counsel does not please your, find better advice, so that you and we all can be rid of the unbearable, devilish burden of the Jews, lest we become guilty sharers before God in the lies, blasphemy, the defamation, and the curses which the mad Jews indulge in so freely and wantonly against the person of our Lord Jesus Christ, this dear mother, all Christians, all authority, and ourselves. Do not grant them protection, safe-conduct, or communion with us. . . . With this faithful counsel and warning I wish to cleanse and exonerate my conscience.
-Martin Luther (On the Jews and Their Lies)
Let the government deal with them in this respect, as I have suggested. But whether the government acts or not, let everyone at least be guided by his own conscience and form for himself a definition or image of a Jew.
-Martin Luther (On the Jews and Their Lies)
However, we must avoid confirming them in their wanton lying, slandering, cursing, and defaming. Nor dare we make ourselves partners in their devilish ranting and raving by shielding and protecting them, by giving them food, drink, and shelter, or by other neighborly acts...
-Martin Luther (On the Jews and Their Lies)
Accordingly, it must and dare not be considered a trifling matter but a most serious one to seek counsel against this and to save our souls from the Jews, that is, from the devil and from eternal death. 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...
-Martin Luther (On the Jews and Their Lies)
He who hears this name [God] from a Jew must inform the authorities, or else throw sow dung at him when he sees him and chase him away.
-Martin Luther (On the Jews and Their Lies)
But what will happen even if we do burn down the Jews' synagogues and forbid them publicly to praise God, to pray, to teach, to utter God's name? They will still keep doing it in secret. If we know that they are doing this in secret, it is the same as if they were doing it publicly. For our knowledge of their secret doings and our toleration of them implies that they are not secret after all and thus our conscience is encumbered with it before God"¦ If we wish to wash our hands of the Jews' blasphemy and not share in their guilt, we have to part company with them. They must be driven from our country.
-Martin Luther (On the Jews and Their Lies)
Undoubtedly they do more and viler things than those which we know and discover.
-Martin Luther (On the Jews and Their Lies)
If I had power over the Jews, as our princes and cities have, I would deal severely with their lying mouth.
-Martin Luther (On the Jews and Their Lies)
They [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, as Moses did... If this does not help we must drive them out like mad dogs.
-Martin Luther (On the Jews and Their Lies)
Well. There you have it.
Luther may not have applauded Hitler... but he sure wouldn't have joined the opposition.
