That's what you say but that's not the way I see Nestorius as coming across...I don't see where he denied Jesus as the 2nd person of the Trinity...
I believe Nestorious the Bishop of Constantinople questioned the divinity of the infant Jesus. He did not deny His divinity though. Part of this controversy was in response to the Arians who were arguing that because the Son was "begotten" He had a beginning, but God is without beginning.
Nestorius was right though in his objection to the term "theotokos" because it leads to the implication Mary was a goddess. All you have to do is look at the RC's with their goddess worship of Mary and you see why he objected to the term.
FWIW, I don't think you will have any kind of a fruitful discussion with the Maryolators. It seems to be a constant with them to ascribe all the beliefs of a controversial person to those that disagree. In this case Nestorius.
I agree with Nestorius about the term "God bearer" but not about the divinity of Jesus as an infant.
Nestorius believed that Christ's Human and Divines Essences were separate that led him to reject that God suffered and was crucified as if Christ body was meaningless shell
The son of God Jesus Christ is LOGOS,dear friend.Anything other than this is Non Christian belief
