To weak?
Cleric BAB, All Good Saves, D8 HD, Light & Medium Armor and Shields, More Spells Known than a Sorcerer, weapon focus & specialization, 3 types of energy resistance 10, wings (fly 60, good), damage reduction 10/cold iron or 10/silver.
Giving them turning for free puts the sprinkles on the icing.
Compare them to the sorcerer who gets worse BAB, one good save, d4 HD (half the size), no armor or ability to cast in armor, less spells known, and a familiar.
The difference between arcane spells and divine spells shouldn't merit that massive of a difference.
