Indeed, the 'godless cleric' concept is key to the monotheistic campaign setting I'm developing....which ostensibly draws from Jewish, Catholic, and Muslim folklore and tradition for supernatural beings. That mechanic lets me leave vague the question of which side the One True God actually favors, yet allow full clerics with full spell progression on all sides of the faith. Their magic comes from their belief that their way is right...and whether it actually is or not is up to the individual character to decide.
