If theory only means 'a view to see'. What is it you are looking at?
If it means to contemplate, then what are you contemplating?
A seperate section of reality?
Is reality divided?
Indeed, the ancient Greek philosophers wondered the same thing. They even established the practice of
theoria in which they would travel to other cities to witness sacred events, report and through the experience be "transformed by the journey of
theoria and the activity of contemplation." The practice and its meaning evolved as you will read in the link.
None of this, however, has anything to do with the original etymology and the meaning of
thea "to view."
Nor, as Paul and others have pointed out, does it have anything to do with the current definitions of theory and theology or the what "reality" is.
You can believe that all of reality is God, that's fine with me and, I am sure, all of us here, but your etymological arguments do nothing to support that idea or the idea that the word theory has anything to do with God.
Besides, words only have the meaning that we humans give to them. They have no other significance.
"You are metaphysicians. You can prove anything by metaphysics; and having done so, every metaphysician can prove every other metaphysician wrong--to his own satisfaction. You are anarchists in the realm of thought. And you are mad cosmos-makers. Each of you dwells in a cosmos of his own making, created out of his own fancies and desires. You do not know the real world in which you live, and your thinking has no place in the real world except in so far as it is phenomena of mental aberration." -
