Really? Huh, I didn't know that.
I like Molly's idea, of the home churches and the adaption of reliegion. I also liked her Vatican idea
I myself say, yeah, why wouldn't they have religion, as I said above, I mean they weren't always hidden from Muggles, and religion is an ancient thing, it's been around for a very long time. They also celebrate religious holidays. This could be a cultural thing, or it may be because there are religious students. I think that religion just isn't something Harry ever thought about or didn't notice. (I'm trying really hard to encompass all religions, not just Christianity.) I personally think there could be religion though.
(Ok, no I'm just going to focus on Christianity)
As a Christian, however, this issue gets more complicated. Many Christians believe Witchcraft to be wrong, so does this mean that the wizarding world can't practise Christianity? This is where I get confused.
However, I still think that the wizarding world could have religion.
