Sentence against Nestorius
Conciliar · Decree · 431 · Greek
The deposition was passed before the Antiochene bishops who supported Nestorius had arrived — the procedural charge his party made at the time, and the one historians still make. The sentence calls him the new Judas and strips him of Constantinople. He was condemned in absence by a council that chose not to wait, and that the Christology has been received does not make the proceedings of that day any less of an ambush.
The text
The sentence
As, in addition to other things, the impious Nestorius has not obeyed our citation, and did not receive the holy bishops who were sent by us to him, we were compelled to examine his ungodly doctrines. We discovered that he had held and published impious doctrines in his letters and treatises, as well as in discourses which he delivered in this city, and which have been testified to. Compelled thereto by the canons and by the letter (anankaios katepeichthentes apo te ton kanonon, kai ek tes epistoles, k.t.l.) of our most holy father and fellow-servant Coelestine, the Roman bishop, we have come, with many tears, to this sorrowful sentence against him, namely, that our Lord Jesus Christ, whom he has blasphemed, decrees by the holy Synod that Nestorius be excluded from the episcopal dignity, and from all priestly communion.
