I've actually never seen my objection seriously considered by theologians. (Non-religious people of course just acknowledge it as self-evidently true.) And I've done a lot of reading on this. Nothing in the passage you quoted is new to me, and nothing in it refutes my argument. I make no assumptions about God's nature at all. I don't even require that the omniscient entity be God (though it certainly could be). I am merely pointing out that omniscience logically precludes certain things, namely, the things that are known to the omniscience to be false, and therefore logically precludes omnipotence.
