Over the past several decades historians have turned a critical eye to the complicity of the German churches in fostering poisonous societal attitudes towards Jews on the eve of the Holocaust.1 Emerging from this research has been the disputed relationship between Christian anti-Judaism and the intense race-based anti-Semitism of the Nazi era. Separating the content and motivation of these two forms of disparagement has allowed Christians to remove themselves from the genocidal equation linked to radical, racist attacks on Jews.2 Susannah Heschel’s The Aryan Jesus tackles this issue by examining the historical backdrop and explicit content of racially motivated attacks on Jews by German Protestants in the years preceding and during the Holocaust. Targeting the Eisenach Institute for the Study and Eradication of Jewish Influence on German Church Life together with the Institute’s leader, Walter Grundmann, her findings may well render obsolete any theoretical dichotomy between religious anti-Judaism and racial anti-Semitism.3
