Ok, I think the most relevant comparison here is to a straight level 6 wizard. He has the apparent spellcasting of a 5th level generalist wizard plus a bunch of stuff.
His hit points are a little less than a 10th level wizard (4d12 compared to 12d4, then lowered due to difference in con bonus).
He gets the base attack of a 6th or 7th level wizard.
No familiar (minor loss)
6th level turning
5th level cleric spells without domains or spontaneous casting.
Gains simple weapons (minor gain).
If you want him to be balanced with a 6th level wizard then I think you are too generous on the turning and divine spells. Perhaps give him one spellcasting class only but can draw from arcane necromancer spells as part of his divine list.
