Council of Ephesus (431 AD)
Third Ecumenical Council, proclaimed Mary as Theotokos, and condemned Nestorius
The Council of Ephesus, convoked by Theodosius II and led by Cyril of Alexandria, declared the Blessed Virgin Mary to be 'Theotokos' (God-Bearer) because the child born of her was not a mere man conjoined to God, but the eternal Son of God made flesh in an indivisible personal union.
Historical Context & Significance
Condemning Nestorius of Constantinople and deposing him, the council catalyzed the earliest permanent ecumenical schism, as East Syriac communities adhering to the theology of Theodore of Mopsuestia rejected the council and coalesced into the independent Church of the East.
