Not sure which thread it was actually in but if I remember correctly it was decided that casting divine revelations is akin to a 'private conversation between god and caster' not the big flash graphic on the screen that you see....
Can someone with a better memory confirm that or tell me I'm losing my marbles please
On the whole....I think the RP route is the one to go too...Although if it comes to a Raising my cleric casts it if she doesn't know
