Many Catholic clerics recognized who the Nazis were immediately:
"The symbol of German National Socialism, the swastika, is a pagan symbol which stands in sharpest opposition to Christianity. Paragraph 24 of the National Socialist program is pagan in its presumption and consequences. It leads, logically, through the destruction of the Christian world order and its substitution through a racial world order to the ancient pagan cult of Wotan. Membership in the National Socialist party is incompatible with the Catholic conscience."
