Islam's rules require too much obedience for my liking. I like the idea of the CoE, they're so scared of their dwindling numbers they let you do what da smurf you like as long as you show up on a sunday.
If I ever regressed into thinking an omnipotent non-interventionist magician created everything I'd go there. An hour every month or so on a sunday for salvation? I'll have some of that.
