The Nazi Party was a Christian political party founded in Germany in 1919. The Christian nature of the Nazi party is well defined in their 25 point charter, point 24 "The Party as such advocates the standpoint of a positive Christianity without binding itself confessionally to any one denomination". Their charter does go on to demand religious freedom for religions that do not offend the morality of the German people (Christian Morality).
It is important to consider that prior to WWI, being a Christian was a requirement for German Citizenship, so "Christian" was synonymous with "German" until this time. Not long after Jews were allowed to become German citizens (for the first time in history), WWI broke out. Thus, the Nazi party plied on "Jewish treachery" which was mean to say the Christian Germans had let the Jews become citizens and the Christian Germans felt the Jews did not do their part in the war in return and thus were responsible for the loosing the war.
