Of all of the rulesets inherited from Dungeons and Dragons 3.0, the Cleric of an ideal, or essentially the godless clerics has always been the one that grinds my garters.
It always came off as for what it was originally intended... a sop to please Fundamentalist mommies and daddies that their local Dungeon Master wasn't going to introudce Tommy and Susie to pagan worship.
Hm, I had never considered that possibility.
I always figured that the philosophical cleric was the result of wanting to give players the opportunity to play a healer without the religious baggage, while feeling constrained from making a new class for the concept by game tradition. (Or simply free up all casters to heal.)
Anyway, thanks for an angle I had never considered. :)
