It would focus more on the God within everyone instead of some invisible man in the sky. It would focus more on teachings of Jesus instead of some ppl basically saying, "Well I accepted Jesus & got saved - even though I can't quote or remember one thing Jesus said the fact I did some feel-good ritual in a church makes me Heaven-bound."
It wouldn't entail going to a church, sitting on your ass, listening to a boring sermon drone on for hrs accompanied by yawns, sighs, and ppl mostly showing up as a social/gossip function. You wouldn't wear your best clothes to the new church - you'd wear work clothes since you'd be going out into the community as a group to perform community service.

No book would be banned. Banning books means denying & withholding knowledge & that's one of THE main sins in the eyes of the true God. People can continue their own beliefs if they want. It won't be marketed as a 'religion' just a lifestyle. That's one reason elite programming has made younger generations shun "religion" (think of how many now say "I'm not religious but I'm 'spiritual'").
