The transcription discusses the concept of Jesus being fully God and fully man, and the debates that took place in the four church councils (Nicaea, Constance, Nobile Ephesus, and Chalcedon) during the Christian Roman Empire. It explains that Jesus is eternal with God, has the same body and soul as a man, acts as one person, and has two united but not mixed natures.
So we've said that Jesus is the man who is God, fully God, fully man, one person, two natures, two wills. And that middle part there says that he is fully God, fully man, one person, two natures. And that's actually a very short summary of the four church-like councils that were held during the Christian Roman Empire. So that's Nicaea, Constance, Nobile Ephesus, and Chalcedon. And I don't know if this is helpful for you, but I've got a map of where we're going.
Just sort of lists two things that were there for each of these major points. Fully God, fully man, one person, two natures. They debated a little bit more than that, so everybody would probably have asserted that those are true, except for maybe that last one, but here's what I think the essence of the debate was. In Nicaea, Jesus was fully God, fully man, he is eternal with God in the same essence as God. In Constance and Noble, that he was fully man, he has the same body as a man, but also the soul of a man.
The third, Ephesus, clarified that Jesus is one person, which means that he acts as one person and he is described as one person. And finally, the fourth ecumenical council, Chalcedon, said that Jesus has two natures and that yes, they are united together, but they are not mixed together.
