I'm pretty sure it has been taken seriously by some people.
Take a look at this commentary on the Second Prophecy by the character Bengt Algotsson.
I don't know the player (actually I don't even know if he's still playing), and I didn't prompt him, or give him OOC clues or anything like that. He just took the time to read through a lot of the sermons and writings I'd posted to the wiki and he came up with a pretty fine interpretation. Surely he wouldn't have taken the time and trouble to do that if he hadn't taken the religion at least a little bit seriously?
I generalize too much. I didn't mean "not a single person does", I meant generally speaking.
