Polemotheos, I enjoyed reading your post...
I would have to disagree with you that God ,"could not possibly materialize all his being into one body"...
Jesus said at Matt 19:26 "With God all things are possible"
The name Yahweh means "He causes to become" as a Witness you would know that the very deffinition of Gods personal name as revealed in the Hebrew texts indictaes that he will become whatever is necessary in order to fulfill his purpose"
If that meant taking on human form , then that is what he would do, should he choose too.
Jesus who created all things, according to Colossians 1:17 Holds the entire universe together in his hands , before comming to earth the scriptures tell us that he shared the same glory as his father (John 17:5)...yet miraculously he came to earth as a man 2000 years ago and dwelt among men.(John 1:14)
Most remarkably of all Colossians 2:9 states "In Him (Christ) dwells all the fullness of the Godhead bodily"
