Sure. Many of the rank-and-file of the Nazi party continued to profess traditional Christianity and attend Church, oblivious to the fact that the teachings of the Nazi party were incompatible with their religion.
You would be surprised at what people believed before the 50's. When I was born there were no Jews or Catholics in our area only Protestants. There was good reason, everyone disliked them and they were not welcome. The nearest Catholic Church was a hundred miles. If someone wanted to discredit you they might call you a Jew or a Catholic. Jews were hated right here in the good old USA by both Catholics and the Protestants. All this started to change in the 50's after the war. In general most people didn't like anyone different from themselves. You simply have no idea of how much things have changed.
