I think you should draw a clearer distinction between “you” (the player) and “your character” (the character the player is playing). Never use “you” to refer to the character, and explain at the beginning that the character the player is playing is a literary character in a different world with a different personality, values, and religion from the player. That would allow you to sidestep all of that coddling to religious sensitivities. Because I find this level of coddling offensive.
Different religions exist, in the real world and in fiction. Different people have different religions. Anybody who has a problem with that is not worth coddling, and isn’t going to play a secular fantasy rpg anyway. But if you have a fictional religion in your game, then you need to actually develop it, with specific beliefs, values and practices, instead of just leaving it up to the player.
The alternative is to just not have a religion in the game. Which is still going to offend the bible thumpers whining about the secularization of society.
