Q. Are you a Nestorian? By saying that Mary is not the mother of God, are you not guilty of separating the two natures of Jesus?

A. The above questions are the essence of an email I recently received from a Roman Catholic. Referring to my article, “Was Mary the Mother of God?” this man said, among many other things, “I smell the stench of Nestorianism!” and “I hope you will recant of the heresy of denying that Mary truly is the Mother of our Lord, the Mother of God.” Because the remainder of his email is relatively level-headed and well-argued, and because his position represents the general position of the Catholic Church, I have decided to reproduce below my answer to him.
