The Problem of Evil (XXVII)

[Neo-Scholastic]

That said, the skeptic cannot say that Christian’s offer no plausible excuses.

1. A tri-Omni entity who can't do better than this world is a contradiction in terms.
2. Lots of excuses, none of them plausible.

Christians don't believe God is "all-powerful" in the sense that He can do the impossible, either. That's not how we define all-powerful. So if you are going to object to the Christian god, then you should do so based on how Christians define the terms they use to describe their god. As far as we're concerned a God that can do anything it is possible to do satisfies the criteria for all-powerful.

Personally, I see nothing problematic about a god for whom some things simply are not possible, such as making square circles, acting contrary to His own nature, or making Himself cease to exist. In order to make a perfect creation, God would have to make another equal to Himself. Doing so would be another God which is also impossible. Therefore God can only create things less perfect than Himself. Could he have done better than this? Maybe he has. I can imagine that because God is infinitely creative, He would actualize creations of various degrees of perfection, from highest Heaven to lowest hell until all possibilities were exhausted. But that's pure speculation on my part and not part of any established doctrine.
