Hitler was born and raised Catholic. Though by adulthood, he seems relatively indifferent to religion; I suspect Nietzschean ideals had entirely replaced his faith by then, but he knew you couldn't openly profess to be atheist or Nietzschean and still have the religious right embrace you.
Throughout his reign he would still profess to be a Catholic. Though behind the scenes he would lament several aspects of Christianity, it's glorification of pacifism, weakness, and it's sheer *Jewishness*.
Hitler would praise Islam as a "warrior's religion" and lamented the fact that it would make a far better primer-of-faith for German national socialism, but it wasn't the religion of his culture, so he didn't have that option.
Guys like Himmler went a different route with it. He would claim that Christianity was real, but that the Jews had subverted the message; he called this "Irminism" it was basically a re-imagining of Christianity where Christ was some Germanic dude.... don't ask me how the fuck he made that work, it's insanity. But Himmler had a lot of half-baked pseudo-historian ideas.
