Second Council of Ephesus

The Council of Ephesus of 449 was convened by Emperor Theodosius II, but later recognized by the Imperial Church as ecumenical council. Rather, it went under the polemical designation robber synod (Latin latrocinium ) in the church historiography. At this council took Patriarch Dioscorus of Alexandria the help of soldiers and militant monks claim to enforce the faith opinion of Eutyches and Monophysitism to help the breakthrough.

The term " Robber Synod " comes from a quote from Pope Leo I, whose Tome was ad Flavianum not read at Ephesus and rejected as an opponent of Monophysitism the resolutions of 449. After Emperor Theodosius II was 450 died, his successor Marcian summoned a council at Chalcedon in 451 a, which should be the fourth Ecumenical Council and on which the decisions were rejected by 449 - this eventually led to the elimination of the Monophysite churches of the Orthodox-Catholic Church.
