No guarantee anyone would believe Ainz. He's an "evil" undead that can slaughter armies. They'd more likely he's trying to wane their faith to weaken them.

Of course, that's what I've been wondering. If Faith based magic is not someone worshipping their god and getting power from them, but pure belief. Simply, their belief that they're getting power is what fuels their magic. The power of positive thinking I guess.
