The Early Church and Peter's Primacy

Letter L, from Pope Leo and the Roman Synod to the People of Constantinople

Synopsis: Leo and the holy Synod write to the people of Constantinople to report that Hilarus the deacon has informed them of all that was done at Ephesus by the presumption of one man; to urge them to stand firm in the spirit of Catholic truth, accepting the apostolic exhortation that it has been granted to them to suffer for Christ as well as to believe in him; and to hold their bishop Flavian before the eyes of their heart as the one who did not fear to suffer all that was inflicted, whose imitators they are urged to be in order to share his crown of faith.

Leo, bishop, and the holy Synod convened in the city of Rome, to the clergy, honorable men, and people of Constantinople, most beloved sons in the Lord.

Chapter I: The Report of Hilarus; The Presumption of One Man Wounded the Universal Church

The things done contrary to all expectation at Ephesus have come to our knowledge and deeply disturbed our hearts with grief — except that our son Hilarus, who was sent by us to Ephesus and who, had he attended the synod, would undoubtedly have kept clear of so great a crime, fled and returned — declining, lest he become an unjust participant in the sentence. For while his voice was withheld from our protest — which the Alexandrian bishop arrogated to himself — he scorned to hear it, dragging unwilling priests into the fellowship of his will: so that those who were compelled by force to subscribe had no cause that we trust will find no favor with the Christian emperor.

Chapter II: Stand Firm; Hold Your Bishop Flavian Before the Eyes of Your Heart

Stand therefore in the spirit of Catholic truth, and receive the apostolic exhortation from the ministry of our voice: Because it has been granted to you for Christ’s sake, not only to believe in him, but also to suffer for him (Phil. 1:29). Do not suppose, most beloved, that the holy Church of God is without divine protection. For the purity of the faith shines all the more brightly when the filth of errors is separated from it. Therefore again and again we both call upon you before the face of the Lord and warn you: do not let yourselves be moved from the faith in which you are founded and in which we know the most Christian emperor perseveres — not by plots, not by the persuasions of anyone; but hold your bishop Flavian before the eyes of your heart — he who did not fear to suffer all that was inflicted for this cause, whose imitators in all things we desire you to be, so that you may share with him the common reward of faith.

Given on the Ides of October, in the consulship of Asturius and Protogenes, most illustrious men.

Notes / Historical Commentary

Letter L is addressed to the clergy and people of Constantinople directly — the same reach-past-the-hierarchy move visible in Letter XXXII to the archimandrites, now extended to the entire Constantinopolitan faithful. Where Letters XLIII–XLV had addressed the emperor, the empress, and the Western episcopal college, Letter L addresses the one constituency in Constantinople that the Apostolic See most needs to hold firm: the ordinary faithful and their clergy, who are at risk of accepting Dioscorus’s imposed outcome as a fait accompli.

Chapter I’s report of Hilarus follows the now-familiar pattern, but with a distinctive addition: Leo explicitly names the legates as having been “sent by us to Ephesus.” The Apostolic See dispatched its representatives; those representatives were refused a hearing; Hilarus alone escaped to bring the account back to Rome. This sequence establishes that the Apostolic See has full knowledge of what happened — knowledge conveyed by its own agent — and that its condemnation of Ephesus II rests on firsthand testimony.

Chapter II’s key sentence is Leo’s direct affirmation of Flavian as “your bishop.” This is not merely pastoral consolation; it is an institutional declaration. Dioscorus had conducted a deposition; the Apostolic See declares it void by continuing to recognize Flavian as the legitimate Bishop of Constantinople. The Constantinopolitan faithful are being told, with the full authority of Leo and the assembled Roman Synod, who their bishop is. The invitation to share Flavian’s crown of faith by imitating his constancy adds a martyrological dimension that would prove prophetic: Flavian died from injuries sustained at the council, becoming in effect the first episcopal martyr of the Eutychian controversy.

The letter closes by noting that it is sent through Epiphanius and Dionysius, notaries of the Roman Church. These are not Leo’s three bishops-and-deacon legates of the June 13 dispatch but administrative functionaries of the Roman see — another channel of communication being deployed simultaneously to ensure the Constantinopolitan community is reached. The systematic coverage of every significant constituency in Constantinople — the archimandrites (XXXII), the emperor (XLIII, XLIV), the empress (XLV), and now the faithful (L) — shows the Apostolic See’s solicitude for all the Churches operating at full intensity in a moment of institutional crisis.
