Maybe I am the secret Catholic!

I was kidding when I called him a Catholic but Joss may have his own version of Heaven actually, he isn't that hopeless. Have you seen his speech when he received the Cultural Humanist award?

He said he was probably a more of a true believer than religious people...

Anyway a writing can use cultural materials without subscribing to the whole system they are part of.
