sentence: Christopher J. Probst in his book Demonizing the Jews: Luther and the Protestant Church in Nazi Germany (2012), shows that a large number of German Lutheran clergy and theologians during the Nazi Third Reich used Luther's hostile publications towards the Jews and their Jewish religion to justify at least in part the anti-Semitic policies of the National Socialists.
