Council of Ephesus
The council judged the dispute involving Nestorius and approved Cyril's defense of the one incarnate Christ. The title Theotokos identifies the one born of Mary as the divine Word made flesh.
Historical context
The proceedings were contentious and involved delayed arrivals and rival assemblies. The 433 Formula of Reunion belongs to the later effort to restore communion, not to the first session itself.
Perspective note
Shared subject; this bundled record was originally written with an Orthodox-informed editorial lens.

Primary sources
In the conciliar dossier received at Ephesus, Cyril writes:
Cyril's first anathema connects the title Theotokos directly to the confession that Emmanuel is truly God.
the Emmanuel is very God, and that therefore the Holy Virgin is the Mother of God
Passage context and translation
Cyril's first anathema, reproduced among the Ephesian documents, grounds Theotokos in the identity of the one born from Mary: Emmanuel, truly God. This is Cyril's anathema, not a standalone council creed.
