On this day in history, August 3, 435... After being condemned as a heretic during the First Council of Ephesus, Nestorius, the Ecumenical Patriarch of Constantinople and founder of Nestorianism, was exiled to a monastery in Egypt by Roman Emperor Theodosius II. In essence, the teachings of Nestorius were opposed because it was argued that he put too much emphasis on the human aspects of Jesus, thereby creating a fracture in the singularity of Christ. For example, the Virgin Mary's title was commonly known as Theotokos or the "Bringer forth of God" but Nestorius argued that the title denied Him His humanity and should be more accurately called Christotokos or "Bringer forth of Christ." Nestorius was challenged by this teaching as being too close to adoptionism, or the idea that Christ had been born a man who had later been "adopted" as God's son. These teachings were condemned as heretical during both the First Council of Ephesus and the later Ecumenical Council of Chalcedon. The Council of Chalcedon resolved the matter by establishing the Doctrine of Hypostatic Union, or dyophysitism, a concept that presumes Christ has one human nature and one divine nature, both united with neither confusion nor division.
