My views on objective morality

[Neo-Scholastic]

If God is omniscient, then does She know that there is nothing She does not know

That is another interesting paradox, but not exactly germane to the discussion at hand. While I am not in a position to present an exhaustive reply, I can give you some indication of how I would approach the issue. The God of Classical Monotheism is fully in act and thus exhausts all potentials as demonstrated by Thomas Aquinas’s First Way, the Argument from Motion. If there is an object of knowledge that a god could potentially know but does not, then that deity is not fully in act and thus would not be the same God identified in the First Way.
