it happens in debating with atheists, that they often claim Hitler was a theist (which is right). And then they often claim that Hitler was Christian. In my opinion, this happens in attempt to show that Christianity is dangerous.Why does it matter?
While I am not claiming that Christians can't be dangerous,
it would be interesting to see how Catholics see their brother. Since he was baptised and never left that church, we see here that the Catholic opinion tends to be that he is a Christian, indeed. See #128.
The Bible however, says you must believe in order to be a Christian, see Romans 10:10. This is at least my interpretation of that verse.
So this thread is an answer to allegations that Christianity is dangerous.
While I do not negate this hypothesis, I want to see what the reasoning behind really looks like.
But of course I do know that many believing Christians voted for him, too and there were voices from within the churches that supported Hitler making an argument from religion.* And this is the point where Christians need to admit that their religion can become dangerous.
* see for instance https://www.eh-tabor.de/sites/default/files/wissenschaftliche_arbeiten/bruederhaus_tabor_ns_zeit.pdf, it's a source in German language that was easy to find for me. It shows the support for Hitler stemming from evangelical churches in Germany back then.
I've discussed it in a Christian message board, and the majority of evangelical Christians seemed to opine that these were actual Christian churches that supported Hitler back then.
