Christians, your God cannot be Perfect.

[Angrboda]

I haven't read MFM's thread, but it seems you are assuming there is only one perfection, which I don't think can be justified. If we imagine a perfect circle, and a perfect sphere, it's evident that both can be examples of perfection without being identical.

As I said, I mean Perfect in the Anselmian sense, which many Christians enthusiastically endorse, that is, "the conception of God as the greatest conceivable being." Can anything be greater than that? How about an infinite number of greatest conceivable beings?

Then your argument doesn't make sense, because either you're equivocating on the meaning of perfection, or asserting that a maximally great perfection cannot create a lesser perfection, which has no foundation in anything you've said. Correction, you assert that only God can be perfect. However this appears as little more than a bare assertion, to which I've already provided counter-examples. It looks like you're equivocating.
