Der Mythus des 20. Jahrhunderts
In 1934, Bishop Galen began to attack the racial ideology of the Nazi regime, partly poking fun at it, partly critiquing its ideological basis as presented by the Nazi ideologist Alfred Rosenberg. He declared it unacceptable to argue that Jewish authorship of the Old Testament diminished its authority, or that morality and virtue were in any way derived from the perceived usefulness of a particular race. In January 1934, he criticized Nazi racial policy in a sermon and, in subsequent homilies, equated unquestioning loyalty to the Reich with "slavery". He spoke against Hitler's theory of the purity of German blood. Bishop Galen also derided the neo-pagan theories of Rosenberg in "The Myth of the Twentieth Century" as perhaps no more than "an occasion for laughter in the educated world", but warned that Rosenberg's "immense importance lies in the acceptance of his basic notions as the authentic philosophy of National Socialism and in his almost unlimited power in the field of German education. Herr Rosenberg must be taken seriously if the German situation is to be understood."
