So, every year around the holiday season, the religious people in my circle tend to put forth some extra effort to convert me, and presumably anyone else they know who is "doing it wrong." While I generally find this to be mildly humorous, as though they think Christmas and atheists are like vampires and garlic or something, it's also a good opportunity to deploy my arguments and hear the new theology or wildly misapplied science. Sadly, this year, it was mostly a terrible argument based on Chinese writing, and the old standby, "God wants to have a personal relationship with you."

This has gotten me thinking. The Abrahamic deity is generally considered to possess "perfect perfection," or the possession of all good qualities in infinitely perfect manner. That is, he is perfectly good, perfectly loving, and perfectly just, and is not perfectly evil.

This poses a problem for the "personal relationship" theology. It seems to me that, by definition, a perfect entity cannot have any desires whatsoever. For example, if I say that "I am perfectly full," this implies that I am in a state where I do not desire or want any more food. If I then find myself wanting food, it could no longer be said that I am "perfectly stuffed," because now I am clearly only "partially stuffed." By the same token, to say that God is in a state of desire or want, implies that he is not perfect in some aspect. I would tentatively say that "personal relationship" theology means that God is not perfectly content to exist by itself, and therefore lacks "perfect perfection."

Thoughts on the implications for theology? Has this been covered before by someone with more letters after their name?

The problem, IMO, is that perfection is an asymptote at best. This is one of the strongest arguments against a 'perfect' deity. It's unattainable. As soon as you define your god as perfect, you've defined it out of existence.

Ah, but god is omnipotent, so he can - if he so wishes - be absolutely perfect, as well as in need of a little ego-boost through your affections.
Don't you atheists ever listen?

It's the whole "mysterious ways" schtick.
