*My reply was, is and always will be:
it is hardly likely!"
CCC 42
God transcends all creatures. We must therefore continually purify our language of everything in it that is limited, image-bound or imperfect, if we are not to confuse our image of God–“the inexpressible, the incomprehensible, the invisible, the ungraspable”–with our human representations. Our human words always fall short of the mystery of God.
CCC 43 Admittedly, in speaking about God like this, our language is using human modes of expression; nevertheless it really does attain to God himself, though unable to express him in his infinite simplicity. Likewise, we must recall that “between Creator and creature no similitude can be expressed without implying an even greater dissimilitude”; and that “concerning God, we cannot grasp what he is, but only what he is not, and how other beings stand in relation to him.”
It doesn’t make sense to refer to God as “a supernatural thinking substance” because God created everything and everyone, nature and supernature, substance and accidents, thinkers, thoughts and the objects of thought. Our definitions cannot apply to the Infinite because to define is to limit and the Infinite is unlimited. How can imperfect beings presume to categorise the Perfect One? The closest descriptions of the Supreme Being are to be found in the Old Testament: “He Who Is” and the New Testament: “God is Love”… Ah, thanks, with you now.
Except it seems to contradict what you said originally, that if the soul has to be associated with a body to think, it would suggest God couldn’t think:-
Or even if we do the soul is unable to think without a body - which suggests that God is incapable of thought!
