The 10 year old Stumps me Again

She was reading a book (in Italian) and ran into a word which wasn't in her vocabulary. She asked me what "Nestoriano" means. I looked at the context. It concerned a chicken who was convinced that she believed in the Nestorian heresy.

I very much regret to report that I don't remember what the Nestorian heresy was (in my memory I did get it down to two possibilities "I think it was either that Christ had a normal human body with a divine soul or maybe that Christ was purely divine with no mortal flesh (4th century heresies came in pairs with catholic orthodoxy achieving compromise at the cost of logical contradiction)." one of which is correct but didn't want to risk misinforming her on this crucial bit of information)

DC elite ringleaders beware, she is even younger than you are.
