The Early Church and Peter's Primacy

Letter CXXVII, from Pope Leo to Bishop Julian of Cos

Synopsis: Leo congratulates Julian on the Jerusalem restoration and the monks’ conversion, acknowledges Proterius of Alexandria’s profession of faith and directs that his see’s privileges be preserved, presses the Paschal inquiry for 455, reports that his Chalcedon letter was read at Constantinople only through the first chapter — suppressing the Canon 28 condemnation yet again — congratulates Aetius on his vindication, thanks Marcian, and reports that Marcian has interceded for Anatolius, who has promised correction and satisfaction in all things pertaining to faith’s observance.

Leo, bishop of Rome, to Julian, Bishop of Cos.

Chapter I: Leo Congratulates Julian on the Palestinian Restoration and Acknowledges Proterius of Alexandria

We have often confirmed the faith of the most Christian prince with evident proofs — giving thanks to our God who deigned to grant such a ruler for human affairs, one who vigilantly protects the causes of the faith and the height of the republic, always opposing the audacities of heretics and permitting no license against the Catholic faith. After God, it is by his beneficence that the bishop of Jerusalem has been received back and the monks invaded by the falsity of heretical perfidy recalled to sanity by august authority. When I received your letters containing these tidings, I hastened to reply not only the same day but nearly the same hour — to make you more certain that all you wrote was received.

I congratulate our brother Proterius, bishop of Alexandria, for sending letters full of satisfaction about his faith — clearly indicating what he holds. I must grant him worthy grace for the sincerity of his faith, so that he lose no honor of his Church and possess his see’s privileges according to the example of paternal antiquity and the unviolated rights of the canons.

Chapter II: Leo Presses the Paschal Inquiry for Easter 455

There was no doubt for us about this year’s Pascha, but we have been inquiring about the future — since Theophilus, bishop of Alexandria of holy memory, assigned to the seventy-sixth year of his table the eighth day before the Kalends of May, a date never celebrated since the time of the Lord’s Resurrection. This must be diligently sought, to remove every occasion of error. In our annals, the fifteenth day before the Kalends of May is openly established and celebrated by our Fathers. Lest diversity arise between us and the East, let your charity urge the most religious and faithful prince in our name — even though the most clement prince had already indicated in his letters that he has delegated this care to the Egyptians with most solicitous inquiry.

Chapter III: Leo’s Chalcedon Letter Read Only Through Chapter I at Constantinople; Aetius Vindicated; Marcian Intercedes for Anatolius

You reported that my letter to the Chalcedon synod was read before the bishops and clergy — but only through the chapter where my agreement appears to confirm the acts of the faith. I marvel that the remaining parts were not equally brought to their notice — since all must especially know that We noted the impious ambition and opposed the new usurpations, so that what antiquity has constituted by the canons be preserved inviolate, as We have always written.

We congratulate the presbyter Aetius — whom you say has been thoroughly vindicated in all things. Know also that I sent a letter to the most Christian prince, thanking him for deigning to indicate his care for the cause of the faith and the security of the republic. He gave us in return another letter, interceding for Bishop Anatolius — that our mind’s grace be granted him — promising his correction and satisfaction in all things pertaining to the observance of the faith.

Dated the fifth day before the Ides of January, in the consulship of the most illustrious Aetius and Studius.

Notes / Historical Commentary

Letter CXXVII opens the correspondence of 454 with a characteristic multi-layered briefing to Julian: good news (Juvenal restored, monks recalled, Proterius’s faith-profession), ongoing problem (Leo’s Chalcedon letter filtered yet again), and a new development (Anatolius’s promised correction through Marcian’s intercession). The letter is a microcosm of the entire post-Chalcedon correspondence in miniature: simultaneous management of multiple Eastern situations, coordinated through Julian as the standing Eastern agent.

The Chalcedon-letter suppression in Chapter III deserves particular notice because it is the third documented occurrence. Anatolius’s strategy is now clearly established: he presents Leo’s confirmation of Chalcedon’s faith definitions to any audience he can reach, while systematically hiding Leo’s nullification of Canon 28. The bishops and clergy of Constantinople hear the confirmation; they do not hear the nullification. Leo’s exasperation — “I marvel that the remaining parts were not equally brought to their notice” — is restrained but pointed. The suppression is not accidental; it is the calculated management of Leo’s correspondence by the bishop who stands most to lose from Canon 28’s nullification being universally known.

The note about Anatolius’s promised correction and satisfaction is the most significant new element. Marcian has interceded; Anatolius has promised — through Marcian — correction in all things pertaining to faith’s observance. Leo records this without either accepting or rejecting it. The verification will come in Letter CXXXII, when Anatolius writes directly to confirm that Andrew has been expelled and Aetius restored. Between this promise and that confirmation lies the full story of how an apostolic directive, channeled through the imperial court, produces compliance from the patriarch of Constantinople — the administrative arc of superior-to-subordinate correction that CXI, CXII, and this letter together document.
