Based on everyone's feedback, this what I think I am going to do. Let me know if I am completely off my rocker (because hey, sometimes I am).
1. remove spell advancement at 1st and 5th level.
2. make Will the only "good" save throw
3. replace the Aura of Warding ability with this one:
Sealed Life (Su): At 3rd level, the Radiant Servant of Pelor gains a +2 sacred bonus to all Fortitude saves made to remove negative levels. This bonus improves to +4 at 8th level.
4. remove the martial weapon proficiency
5. change the hit dice to d8
Whadda ya think?
