... Blink. Blink.
Yaaaaagh. I really don't think I like this.
Let's look at what this does, all for one 9th-level spell slot:
- A double-strength Righteous Might, with a weird 'size' natural armor bonus (read: effectively unnamed, since it'll stack with anything) and rules on attack and AC penalties that don't match the RAW. (Normally, you'd just grow two size categories and take the appropriate attack and AC penalties - a Large character, frex, would become Gargantuan, exchanging a -1 penalty for a -4.) As a side note, this alone would probably justify a 9th-level spell slot, as you're doubling a 5th-level spell's effect.
- The attack bonus of Divine Power, one of the most overblown 4th level spells in the game. Call it +3 spell levels minimum.
- A Bless effect, with one-tenth the duration but more than twenty times the area of effect. Provides a much better save bonus, too. If we assume the duration nerf counters out half the effect increase (which is real doubtful - the duration nerf is likely pointless at this stage), it's still a minimum of +3 or +4 spell levels.
- A free Aid effect on all allies who worship the same deity. Call it +4 spell levels minimum (yourself and your cohort), and quite possibly +16 or so as the entire party gets to buff. If you're leading an army, yeooouch.
- A Bane effect, same duration and range shifts as the Bless, and allowing no save or spell resistance. The lack of a save likely makes this something like a +7 spell level effect, though that's a complete WAG as there's nothing in the rules to compare against.
- Four levels' worth of free metamagic get applied to all buff spells you cast. The spell level of this one isn't even possible to WAG - casting even just half a dozen group buffs that are automatically widened and enlarged provides 24 levels' worth of metamagic gratis.
So that's 27 spell levels' worth of effect, plus an extra side benefit or three with value impossible to calculate. And takes one action to cast, for the benefits of half a dozen lesser spells. A wee bit overpowered, wouldn't you say? My advice: borrow Greater Aspect of the Deity from Complete Divine - it has the same intent, is already published and playtested, and is a lot, lot, LOT more balanced.
Yaaaaagh. I really don't think I like this.
Well thank you
Futhermore:The size onus to natural AC is in the Monster Manual,it is not weird at all. And considering the penalty to Dex and size penalty to AC,it ends up to amount a measly +1. Not to mention that you become a great target for rays.
Let me remind you that other domains offer shapechange
And considering spell levels, not everytime it is 1+1=2
- A free Aid effect on all allies who worship the same deity. Call it +4 spell levels minimum (yourself and your cohort), and quite possibly +16 or so as the entire party gets to buff. If you're leading an army, yeooouch.
So a +1 bonus on allies and a -1 penalty on enemies. At 20th level. Broken. Sorry but i disagree.
- A Bane effect, same duration and range shifts as the Bless, and allowing no save or spell resistance. The lack of a save likely makes this something like a +7 spell level effect, though that's a complete WAG as there's nothing in the rules to compare against.

I think you underestimate the reasoning behind this spell. It is a kind of battletide for important big battles, were there are lot of low level soldiers.
