My position on no Raise Dead does create some interesting questions as to the nature of the campaign setting. Rather than trying to stress myself with definitive and logical answers, I'll just explore the ideas and then leave them be. Ultimately, the answer is of little importance so long as Clerics are casting spells.
Since Jesus is the only person to have ever resurrected, the monotheistic God of Abraham is definitely the supreme power in the universe. There's no doubt that he is the big man. But I also want to have Clerics of pagan religions, Druids, and spell casters who follow all of the world's religions.
Can they coexist? Is it that only the mortal followers of God who insist all other beliefs are false? Or maybe all other divine powers are actually derived from Satan, channeled through and disguised so as to lead souls away from the path to God?
From a game mechanics point of view, Druids and Clerics can choose any religion and still cast spells. Ultimately, the answer to this question isn't really necessary. Maybe it will come up one day in play, but until I actually start a campaign, I can't even begin to start on the way to reaching that need.
So just food for thought.
