Johannes Steizinger writes "Rosenberg clearly played a major role in the establishment of Nazi ideology" and that "Ideology is regarded as a necessary, but not sufficient cause for participation in genocide" During the
Nuremberg Trials, Justice
Robert H. Jackson referred to the book as a "dreary treatise[s] advocating a new and weird Nazi religion". "Mythus" is written as an imitation of a scholarly book and Viereck notes that "Rosenberg bores both the uneducated and the well educated, but is the god of the semi-educated, whom earnest dullness and obscure grandiloquence impress as scholarly and authoritative". In his Nuremberg Trials testimony, the
extermination camp commandant
Rudolf Höss said that this book was one of the sources of his own anti-Semitism. Despite Nazi official support for
The Myth of the Twentieth Century and Rosenberg's prominent role in promoting Nazi ideology
Adolf Hitler declared that it was not to be considered official ideology of the
Nazi Party and he privately described the book as "mysticism" and "nonsense".
Albert Speer claimed that Goebbels mocked Alfred Rosenberg. Goebbels also called the book a "philosophical belch".
Hermann Göring said: "if Rosenberg was to decide ... we would only have rite,
thing, myth and such kind of swindle."
Gustave Gilbert, the prison psychologist during the
Nuremberg Trials, reported that none of the Nazi leaders he interviewed had read Rosenberg's writings. However Gilbert's notes from the Nuremberg trials repeatedly show Rosenberg's influence. Although he did take very high-level positions within the Nazi state in managing propaganda, looting artworks, and overseeing Nazi rule in the Baltics and Soviet territories, the overt
anti-Christian sentiment in Rosenberg's book made it awkward to give Rosenberg positions of prominence when the Nazis ascended to power. Even in their stronghold Hamburg only 0.49% of the inhabitants identified as belonging to the anti-Christian neopagan faith movement (in 1937), whereas the
German Christians and their
Positive Christianity had a strong standing. Many of the attacks on the book after its 1930 publication came from its explicit anti-Christian message. In 1934,
The Myth of the Twentieth Century was put into the
Index Librorum Prohibitorum (the official list of books forbidden by the Catholic Church) by decree of the
Holy Office for scorning and rejecting "all dogmas of the Catholic Church, and the very fundamentals of the Christian religion". Rosenberg wrote two supplements to the work, replying to Catholic and Protestant critics. In the first,
On the Dark Men of Our Times: A Reply to Critics of the Myth of the Twentieth Century, he accused Catholics of attempting to destroy the national character by promoting separatism within Catholic parts of the country. His second reply,
Protestant Pilgrims to Rome: The Treason Against Luther and the Myth of the Twentieth Century, argued that modern
Lutheranism was becoming too close to Catholicism. ==Translations==
