Cavaradossi, is the following an accurate assessment in your opinion:
Eutyches (Byzantine monk) - argued that Jesus’ human nature ceased to be which gave way to the heresy of Monophysitism, and it spread throughout the eastern church, forcing Flavian (patriarch of Constantinople) - to call a local synod to condemn it and as history shows, Eutyches refused to submit to the synod, appealing his case to Pope Leo I. He wrote:
“I take refuge, therefore, with you, the defender of religion and abhorrer of such factions. …I beseech you not to be prejudiced against me by their insidious designs about me, but to pronounce the sentence which shall seem to you right upon the Faith.”
Response to Eutyches:
"We exhort you, honorable brother, that you obediently listen to what has been written by the blessed Pope of the city of Rome, since blessed Peter, who lives and presides in his own see, offers the truth of faith to those who seek. For we, in our zeal for peace and faith, cannot decide questions of faith apart from consent of the Bishop of Rome. – Peter Chrysologus of Ravenna to Eutyches, Ep 25
And of course Eutyche would not submit and the eastern emperor supported Eutyches’ stance. Eutyche then persuaded the emperor to call another council in Ephesus (“Robber Council”) - in which Rome was ignored and Monophysitism declared to be the orthodox doctrine of the Church. At this same council several other eastern bishops, such as Theodoret of Cyrus and Eusebius of Doryleum were deposed from their sees for refusing to embrace Monophysitism and they too appealed to Leo, saying:
Code:
*We hasten to your Apostolic See in order to receive from you a cure for the wounds of the Church. For every reason it is fitting for you to hold the first place, inasmuch as your see is adorned with many privileges. I have been condemned without trial. But I await the sentence of your Apostolic See. I beseech and implore Your Holiness to succor me in my appeal to your fair and righteous tribunal. Bid me hasten to you and prove to you that my teaching follows in the footsteps of the Apostles. -- Theodoret to Pope Leo, Ep 113*
*The Apostolic throne has been wont from the beginning to defend those who are suffering injustice. I entreat Your Blessedness, give me back the dignity of my episcopate and communion with yourself, by letters from you to my lowliness bestowing on me my rank and communion. -- Eusebius of Doryleum to Pope Leo
Flavian also appeals to Leo:
*“When I began to appeal to the throne of the Apostolic See of Peter, the Prince of the Apostles, and to the whole sacred synod,
which is obedient to Your Holiness, at once a crowd of soldiers surrounded me and barred my way when I wished to take refuge at the holy altar. …Therefore, I beseech Your Holiness not to permit these things to be treated with indifference…but to rise up first on behalf of the cause of our orthodox Faith, now destroyed by unlawful acts. …Further to issue an authoritative instruction…so that a like faith may everywhere be preached by the assembly of an united synod of fathers, both Eastern and Western. Thus the laws of the fathers may prevail and all that has been done amiss be rendered null and void. Bring healing to this ghastly wound.”
*
Pope Leo then manages to get the emperor to call the Council of Chalcedon, comprised of basically all eastern bishops and Leo’s Tome against Monophysitism, and for the orthodox teaching of the two natures of Christ is read and embraced with the following pronouncement:
*“This is the faith of the fathers! This is the faith of the Apostles! So we all believe! thus the orthodox believe! Anathema to him who does not thus believe! Peter has spoken thus through Leo! . . . This is the true faith!’” *
It ends with the council fathers recognizing Pope Leo as the successor of Peter and the Head of the Church, by saying, via letter:
*
You are set as an interpreter to all of the voice of blessed Peter, and to all you impart the blessings of that Faith. – Chalcedon to Pope Leo, Ep 98
*
For if where two or three are gathered together in His name He has said that there He is in the midst of them, must He not have been much more particularly present with 520 priests, who preferred the spread of knowledge concerning Him …Of whom you were Chief, as Head to the members, showing your good will. – Chalcedon to Pope Leo (Repletum est Gaudio), November 451
*Knowing that every success of the children rebounds to the parents, we therefore beg you to honor our decision by your assent,
and as we have yielded agreement to the Head in noble things, so may the Head also fulfill what is fitting for the children. – Chalcedon to Pope Leo, Ep 98
*Also we see the recognition that Peter, as per Matthew 16, is the rock on which Jesus’ church is built:
"Wherefore the most holy and blessed Leo, archbishop of the great and elder Rome, through us, and through this present most holy synod together with the thrice-blessed and all-glorious Peter the Apostle, who is the Rock and foundation of the Catholic Church, and the foundation of the orthodox faith, hath stripped him (Dioscorus, Bishop of Alexandria) of his episcopate, and hath alienated from him all hieratic worthiness." Acts of Chalcedon
