Soon afterwards, a letter was posted in Constantinople that correlated Nestorius’ teachings with that of Paul of Samosata, an heretical figure from the previous century that had also denied or otherwise challenged the divine nature in Christ.
At this time a presbyter in Constantinople named Eutyches was in alliance with Eusebius of Dorylaeum in opposition to Nestorius, but it is unclear whether either played a major role in the proceedings of the council beyond accusation, which was largely directed by Cyril of Alexandria.
At the synod Eusebius of Dorylaeum presented Flavian with a letter, detailing his complaints against Eutyches, as well as making known his willingness to be a witness against him personally.
I besought him to desist and yield; as, however, he persisted, what could I do?” When Eutyches finally stood before the council, he refused to revoke his teachings and was deposed as a heretic.
Flavian was beaten or somehow injured in the ensuing riot so that he died a short time later, but Eusebius found sanctuary with Pope Leo I through a letter of appeal.
Dioscorous was deposed, Eutyches was condemned a second time, and Eusebius of Dorylaeum was reinstated as bishop; Flavian’s name was also cleared in the annulment of the decisions made at the Latrocinium.
He together with me was unjustly deposed by Dioscorous.” The most important outcome of the struggle was a statement of belief known as the Chalcedonian Definition of the faith, which Eusebius of Dorylaeum helped to draft, though his exact significance in that capacity is uncertain.
