The Early Church and Peter's Primacy

Letter CLXX, from Pope Leo to Gennadius, Bishop of Constantinople

Synopsis: Leo complains that Timothy Aelurus has been permitted to come to Constantinople despite his expulsion from Alexandria; he instructs Gennadius that no hope of restoration is to be left him; and directs that Aelurus not be permitted to mix in any public or private conversation with anyone, lest an assembly form under the pretext of correcting his faith.

Leo, bishop, to Gennadius, bishop of Constantinople.

Chapter I: Leo Complains of Aelurus’s Presence at Constantinople and Directs That He Be Denied All Contact

From the letters of your charity, and from the account of our brother co-bishops Domitianus and Germinianus, I have learned that Timothy — after being expelled from the city of the Alexandrian Church — has been permitted to come to Constantinople through the efforts of some who are enemies of the faith. This was arranged so that, since he is constrained by the unanimous sentences of all the Lord’s priests, he might at least show unwillingly some appearance of conversion to the Catholic faith — and so that, being condemned as someone ejected on account of heretical perversity, he might seem to be returning to Alexandria having consented to apostolic doctrine. But this he will never do willingly — since it stands powerfully against him that, while the legitimate bishop was still living, he was the invader of so great a see, and proved to be the author of crimes hitherto unheard of.

Therefore your charity must strive and labor — renowned as you are — that no conversation with so evil a man be permitted, whether privately or publicly; and that no assembly be given occasion under the pretext of correcting him, lest he gain freedom to return, about whom the most Christian emperor has already issued his edicts. Work with all your effort and watchful attention to serve the unity of the Church, dearest brother, so that the support of his backers may be taken from him, and an orthodox bishop may be consecrated for the Alexandrians from among the Catholic clergy according to the ancient custom — since the parricide cannot otherwise be abandoned by his defenders unless the Alexandrian Church, which must be restored to the honor of the Fathers and to its own liberty, receives a shepherd for the healing of all.

Given on the fifteenth day before the Kalends of July, in the consulship of Magnus and Apollonius. Through Philoxenus, agent in affairs.

Notes / Historical Commentary

Letter CLXX, dated June 17, 460, is written on the same day as Letter CLXIX to the Emperor — the second letter of a coordinated same-day dispatch that continues the pattern visible throughout the entire Alexandrian correspondence, from the three-letter cluster of July 11, 457 through the six-letter cluster of September 1 and the December 1 letters. Even in the resolution phase of the crisis, Leo does not write to a single party; he writes simultaneously to emperor and patriarch, each letter calibrated to its recipient’s specific role in the outcome he has defined.

The practical complication Letter CLXX addresses is Aelurus’s unexpected appearance in Constantinople. His expulsion from Alexandria has not ended the crisis; it has simply moved it. By arriving in the imperial capital, Aelurus gains proximity to the court, to the clergy, and to the potential supporters who might organize a campaign for his restoration. Leo’s response is total isolation: no private conversations, no public assemblies, no meetings under any pretext. The prohibition of both channels simultaneously — private and public — reflects a clear understanding of how such restoration campaigns worked. An assembly ostensibly convened to examine Aelurus’s faith would imply that the question is still open; private conversations with sympathetic clergy or courtiers could build the momentum for such an assembly. Leo closes both routes before either can be exploited.

The letter’s closing requirement — that an orthodox bishop be consecrated for Alexandria “according to ancient custom by orthodox Egyptians” — makes a precise jurisdictional distinction that runs throughout Leo’s Alexandrian correspondence. Leo does not claim the right to appoint the Bishop of Alexandria. The right of consecration belongs to the Egyptian suffragan bishops, as the ancient custom has always established. What Leo claims is the right to define the conditions of legitimacy — the candidate must be orthodox, untainted by Eutychian error, and in harmony with apostolic doctrine as the Apostolic See has defined it. This distinction is not diplomatic modesty; it is the precise architecture of ordinary and immediate jurisdiction. Rome defines the standard; the local church acts within the standard Rome has established. The appointment belongs to the Egyptian bishops; the norm against which it is measured belongs to Rome.

The letter is addressed to Gennadius, Anatolius’s successor as Archbishop of Constantinople, in the first communication Leo sends him in the surviving corpus. The contrast with the Anatolius correspondence is quietly significant. Leo wrote to Anatolius repeatedly over four years — directing, rebuking, escalating, finally bypassing him to write directly to the Constantinople clergy in Letter CLXI. The Atticus affair consumed five letters. The tone of those letters grew increasingly exasperated. Gennadius receives a single, direct, firm communication with no history of noncompliance behind it and no rebuke in it. The relationship begins clean. What Leo expects of him — deny Aelurus all contact, support the orthodox appointment, serve the unity of the Church — is stated once, clearly, as the instruction of one bishop who knows his authority to another who is expected to comply.
