Very interesting. I appreciate your investigation of both heaven and earth.
My response is to prefer the moldy and ancient creed from 300 A.D. “God from God. Light from Light.” Thus, it is helpful to investigate the “relations” within the Trinity.
I think your investigation of the Trinity is leading to the investigation of Christology: whether Jesus is the divine Second Person? Yes. Look at His words and His miracles. They match.

Yes, what I wrote isn’t poetic or pretty or pithy. I also neglected to include much in the way of extolling the Father and the Son. I chose only to address the core of the Trinity mystery, a mystery that only persists because of a lack of understanding on our part.
I’ll leave it to someone else to compose something with grand wording.
