1 Historical Background
1.1 Relics of Nestorianism
After the Council of Ephesus had condemned Nestorianism, there remained a conflict between patriarchs John of Antioch and Cyril of Alexandria. Cyril claimed that John remained Nestorian in outlook, while John claimed that Cyril held to the Apollinarian heresy. The two settled their differences under the mediation of the bishop of Boerea, Acacius, on April 12, 433. In the following year, Theodoret of Cyrrhus assented to this formula as well, apparently putting a rest to Nestorianism forever.
However, the works of two long dead Antiochean theologians, Diodorus of Tarsus and Theodore of Mopsuestia were at this time translated into Syriac, which led to a new blooming of the heresy among the Armenians. By the intervention of Proclus of Constantinople, the two theologians were condemned throughout the East, but this situation would later provide the material for the Second Council of Constantinople some hundred years later.
