Following H. S. Chamberlain and other "völkisch" theorists, he believed that Jesus was an Aryan (specifically an Amorite or Hurrian Hittite), and that original Christianity was an "Aryan" (Iranian) religion, but had been corrupted by the followers of Paul of Tarsus. The "Mythus" is very anti-Catholic, seeing the Church's cosmopolitanism and "Judaized" version of Christianity as one of the factors in Germany's spiritual bondage. Rosenberg particularly emphasizes the anti-Judaic teachings of the heresies Marcionism and "Aryo-Persian" Manicheanism as more representative of the true, "anti-Judaic" Jesus Christ and more suited to the Nordic world-view. Rosenberg saw Martin Luther and the Reformation as an important step forward toward reasserting the "Aryan spirit", but as ultimately ambiguous in not having gone far enough in its founding of just another dogmatic church.
