Um, with this new religion, are there any rules или commandments? Any special celebrations?

Well, we worship the Cullens obviously, and that includes Bella. The only celebrations that I'm certain of are Edward and Bellas birthday. Ты believe that the Cullens are real and that Stephanie is the (or one of the) best authors ever. Ты believe that if Ты are good on Earth Ты will spend eternal life with the Cullens, and if Ты are not then Ты will be sent to James' cave. I think that's decided by the Volturi. Umm...OH! And Ты should read at least a page of a Twilight book a день :D
