“”What God “thinks” is what is.””
What “is” was already known in “one now eternally” and involved no thought.
A thought would be a procession from something known by God,thus God would be moved.
I need, if you can think of one, a reference to further examination of this proposition.
Clearly, if we speak of God thinking (or speaking) in one way we are anthropomorphizing. But I think that it is not for nothing (duh) that John calls what we later believe to be the 2nd person of the Trinity, "the Word," and that, if we think about thinking (I'm getting a headache here ...) we realize that it is bound up with "wording".
