Description:
The Council was called by Emperor Marcian to set aside the 449 Second Council of Ephesus. Its principal purpose was to assert the orthodox catholic doctrine against the heresy of Eutyches; that is Monophysites, although ecclesiastical discipline and jurisdiction also occupied the council's attention.[1]https://en.wikipedia.org/wiki/Council_of_Chalcedon
