Running clerics as spiritual counselors?

[Henry]

Or even a cleric of Erythnul....

"Is something toubling you, my son?"

"Yes, Father McMurder, there is. I can't decide whether to use the Cold Iron Sword or the Adamantine Scythe on the peasants."

"Good, Good... carry on, then."

Or do you want to have a caste of "mundane" couselors and mediators in addition to priests?

In Eberron, this role is usually taken by Experts and Adepts. You then have a nonadventuring cleric, who is trained in the religion's mysteries, can hold services, can do some counseling (in the case of Experts, and to a lesser extent Adepts), and is the iconic "parish priest." In my eyes, going to the Cleric of Pelor or the Cleric of Chauntea would be like going to a Knight Templar or Knight Hospitallar for spiritual guidance; maybe it would net some good, but they're not the best person for the job. It's our view of religious leaders as non-combatants that help us see them as counsellors, but D&D Clerics are combatants first and foremost.
