Sure. Like they did for millenia before that too. Having adopted christianism doesn't mean people get perfect or all good or something.
It's more of a moral compass than actual everyday conformance. We might point the "hypocrisy" but then we ignore the importance of having a moral compass, even if don't follow it all the time, which is that it helps shape mentalities, laws and practices.
And that's something that doesn't happen in a day -- it takes centuries of slow progress, while the new values kick in, to the point that their nominal carrier isn't even needed anymore (e.g. we now have codified christian originated values in non-religious forms, including in the Declaration of Independence).
>Also, the Nazis thought they were doing God's work; they had written on their belt "God is with us" (Gott mit uns), which they did not invent (the origin is ancient) but did not suppress either.
They never had any special relationship with the church -- only attempted to keep it to not alienate the huge christian population, but first cleaning it of jewish influence (including lots of new testament). The "Gott mit uns" is just a relic, not a central tenet of their philosophy.
Which is not exactly tied to the christian god's either, it has more to do with the pagan gods of the past, the kind Wagner also celebrated. Early tendencies in 20th century Germany, that later turned pro-nazi, were in favor of such a pagan revival, including naked dances/rituals in the forests, occultism, and other such BS.
The fact that Jesus was jewish itself is enough of an issue for most top nazi's to avoid christianity altogether (although they also maintained that he wasn't, in an attempt to keep the devout masses with them).
