The reason you guys have this problem in the first place is because your religion isn't giving you new things to do with it. Look what's active: anime discussion with new animes with new styles and stories to discuss. War discussion with new tactics and battles constantly appearing.
Christianity didn't have this kind of problem in the day of Christ because everything was evolving and everyone clearly understood the mission and their part in it. When people aren't getting new ways to find success, they make their own entertainment by fighting over bullshit. Even your censorship problem isn't even fighting over the newist Christianity developments to develop more miricals. It's over what the god thinks is the best way of worship (something neither of you expect him to clear up.)
Here's what you need to do to get your board back on track:
Change up the lore so you have something to discuss, make sure you're united by actually making progress toward heaven
Example: set a date for end of the world, and visibly have god show everyone's status after death so people stay on their toes.
Change up the practice to build feelings of progression, make sure everyone has something to work on
Example: find ways to enhance your bodies to "cut off the arm that caused sin" a chip that deletes lust feelings unless triggered by the church to get you to reproduce, another that causes you to be unable to lie or steal. You can have badass underwater baptisms where you have to swim through an underwater tunnel to get back to the surface but there are such great temptations no one who still feels lust/greed could stop himself from straying and drowning.
Do projects ON THE BOARD
Example: invent new, more powerful prayers that get rid of more sins, watch live streams of the pope doing sacrefices, make threads to test out and implement the above.
