Q: On 17 December 1941, seven Protestant regional church confederations issued a statement agreeing with the policy of forcing Jews to wear the yellow badge, "since after his bitter experience Luther had already suggested preventive measures against the Jews and their expulsion from German territory." According to Daniel Goldhagen, Bishop Martin Sasse, a leading Protestant churchman, published a compendium of Luther's writings shortly after Kristallnacht, for which Diarmaid MacCulloch, Professor of the History of the Church in the University of Oxford argued that Luther's writing was a "blueprint." Sasse applauded the burning of the synagogues and the coincidence of the day, writing in the introduction, "On 10 November 1938, on Luther's birthday, the synagogues are burning in Germany." The German people, he urged, ought to heed these words "of the greatest antisemite of his time, the warner of his people against the Jews."
