Ecclesitheurge and the Cloistered Cleric greatly disagree with you...
The cloistered cleric being the archtype that is even LESS focused on spellcasting than the normal cleric. And the Ecclesitheurge retaining medium BAB, two good saves, and D8 hit dice over the wizard...representing LESS of a focus on spellcasting. Was what I wrote somehow unclear?
The cleric was supposed to be the divinely gifted priest who could provide miracles (i.e. MAGIC). The fact that Clerics are FULL CASTERS should tell you that. The cleric IS THE DIVINE EQUIVALENT TO THE WIZARD.
WRONG. Gygax explicitly described clerics as warrior-priests in earlier editions of D&D, citing the Knights Templar as an inspiration; and the class has retained this focus up through Pathfinder. Second edition D&D books even pointed out the existence of non-adventuring spellcasting (or miracle-working) priests who did not have skill with arms and weaponry.
In case you are still having problems with this conceptually, the cleric retains: Medium armor and simple weapon proficiency, two good saves, superior hit dice, medium base attack bonus progression, and the ability to cast spells without problem in heavy armor over full arcane casters (traits which have become incorporated into divine magic as a whole). These are elements that represent less focus on study and spellcasting. Or one could alternately point out that full arcane casters typically get the worst hit dice, base attack bonus, etc to represent their spellcasting focus.
Combat Cleric (pretty much taking the fighter's job)Heal/Buff bot (which the spell list will pretty much look exactly like the combat cleric because he is essentially a combat cleric casting his spells on...
And...this just suggests to me that you are in need of some more play experience.
