According to American historian Lucy Dawidowicz, antisemitism has a long history within Christianity. The line of "antisemitic descent" from Luther, the author of On the Jews and Their Lies, to Hitler is "easy to draw." In her "The War Against the Jews, 1933-1945", she contends that Luther and Hitler were obsessed by the "demonologized universe" inhabited by Jews. Dawidowicz writes that the similarities between Luther's anti-Jewish writings and modern antisemitism are no coincidence, because they derived from a common history of "Judenhass", which can be traced to Haman's advice to Ahasuerus. Although modern German antisemitism also has its roots in German nationalism and the liberal revolution of 1848, Christian antisemitism she writes is a foundation that was laid by the Roman Catholic Church and "upon which Luther built." Dawidowicz' allegations and positions are criticized and not accepted by most historians however. For example, in "Studying the Jew" Alan Steinweis notes that, "Old-fashioned antisemitism, Hitler argued, was insufficient, and would lead only to pogroms, which contribute little to a permanent solution. This is why, Hitler maintained, it was important to promote 'an antisemitism of reason,' one that acknowledged the racial basis of Jewry." Interviews with Nazis by other historians show that the Nazis thought that their views were rooted in biology, not historical prejudices. For example, "S. became a missionary for this biomedical vision... As for anti-Semitic attitudes and actions, he insisted that 'the racial question... resentment of the Jewish race... had nothing to do with medieval anti-Semitism...' That is, it was all a matter of scientific biology and of community."
