“That only explains your personal opinion of Aquinas,Dear Brother, that is backed up with no substance.”
There isn’t enough bandwidth on this site to post the corpus of works of the Ante Nicene, Nicene and Post Nicene Fathers, sfa. Aquinas was simply outside the consensus patrum with regard to our ability in any fashion to partake in the ousia of God, even in terms of “seeing it” other than of course with Christ. I urge you to read The Fathers. At an absolute minimum, go to a library and get volume 4 of the Philokalia and read +Gregory Palamas’ “Topics of Natural and Theological Science”. For now, might want to consider reading this recent piece (remembering the distinction between hypostasis and ousia and ousia and energies):
