context_page_description: Oriental Orthodoxy is the communion of Eastern Christian Churches that recognize only three ecumenical councils — the First Council of Nicaea, the First Council of Constantinople and the Council of Ephesus. They reject the dogmatic definitions of the Council of Chalcedon. Hence, these Churches are also called Old Oriental Churches or Non-Chalcedonian Churches.
context_section_description: According to the canons of the Oriental Orthodox Churches, the four bishops of Rome, Alexandria, Ephesus (later transferred to Constantinople) and Antioch were all given status as Patriarchs, the ancient apostolic centers of Christianity by the First Council of Nicaea (predating the schism). Each patriarch was responsible for the bishops and churches within his own area of the universal catholic Church (with the exception of the Patriarch of Jerusalem, who was independent of the rest) with the Bishop of Rome as "first among equals" as the successor to Peter and seat of the Petrine Ministry of unity and authority.
  The schism between Oriental Orthodoxy and the rest of the Church occurred in the 5th century.  The separation resulted in part from the refusal of Dioscorus, the Patriarch of Alexandria, to accept the Christological dogmas promulgated by the Council of Chalcedon on Jesus's two natures (divine and human). The Oriental churches accepted that Christ had two natures, but insisted that those two natures are inseparable and united. Dioscorus would accept only "of or from two natures" but not "in two natures." 
  To the hierarchs who would lead the Oriental Orthodox, the Chalcedoian proclamation was tantamount to Nestorianism, which the rejected. Arising in the Alexandrian School of Theology, Nestorianism advocated a formula stressing the unity of the Incarnation over all other considerations.
  The Oriental Orthodox churches were therefore often called Monophysite, although they reject this label, as it is associated with Eutychian Monophysitism. They prefer the term "non-Chalcedonian" or "Miaphysite" churches. Oriental Orthodox churches reject what they consider to be the heretical Monophysite teachings of Eutyches and of Nestorius as well as the Dyophysite definition of the Council of Chalcedon. As a result, the Oriental patriarchs were excommunicated by the bishops of Rome and Constantinople in 451, formalizing the schism.
  Christology, although important, was not the only reason for the Coptic and Syriac rejection of the Council of Chalcedon; political, ecclesiastical and imperial issues were hotly debated during that period.
