Ive read much into the subject and the truth is that the nazis were all over the map in regards to the Christian faith. They used it when it was advantageous but they always had a strong distaste for the power of the Catholic church over Catholics in both Germany, allied countries and conquered lands. The authority was dangerous to them as it superseded their own authority...at least amongst the Catholics.
There are documented cases of German senior officers being questioned on their faith and allegiance, passed up for promotion etc...speaking of the Catholics here
