Orthodoxy is Christianity. Its actually the original denomination before Roman Catholicism split off and then all the Protestants.

National Socialism is a misnomer.

The term "National Socialism" arose out of attempts to create a nationalist redefinition of socialism, as an alternative to both Marxist international socialism and free-market capitalism. Nazism rejected the Marxist concepts of class conflict and universal equality, opposed cosmopolitan internationalism, and sought to convince all parts of the new German society to subordinate their personal interests to the "common good", accepting political interests as the main priority of economic organisation,[13] which tended to match the general outlook of collectivism or communitarianism rather than economic socialism.
