The third ecumenical council, held at Ephesus in AD 431, is often considered to be the first of two highly Christologically-orientated councils (the second being that at Chalcedon in 451). In it, Nestorius was considered and condemned, and considerable attention was paid to the ongoing project of articulating Nicaea in light of current debates.
