The Early Church and Peter's Primacy

Letter CLXXII, from Pope Leo to the Presbyters and Deacons of the Alexandrian Church

Synopsis: Leo urges the Alexandrian clergy to preserve concord around their new bishop, noting that the beast that devastated the Lord’s vineyard has been driven away; and directs them to bring back those who were led astray by the heretics through patience, gentleness, and the remedy of penance.

Leo, bishop, to the presbyters and deacons of the Alexandrian Church, his most dear sons in the Lord, greeting.

Chapter I: Leo Rejoices in the Love Between the New Bishop and His Clergy, and Urges Unity

I rejoice and exult in the Lord over the most devout spirit among you — for as your writings make clear, the shepherd is seen to love his flock and the flock its shepherd. Eager therefore for one another, as the Apostle says, to preserve the unity of the Spirit in the bond of peace (Eph. 4:3), press forward to the fruit of true patience. What indeed could you more worthily will or do than to make use of the faith of the most glorious emperor — with the help of God’s grace — for the advancement of the most solid peace, now that the beast which had with singular ferocity devastated the Lord’s vineyard, as the prophetic psalm sings, has been driven far away? Since in the Lord’s sheepfold there are no longer the snares of thieves nor the attack of brigands to fear, let your whole community return to concord, and let unity — directed by the teaching of the Holy Spirit — be sought in all things: for the sake of which the Apostle says, not seeking what is useful to me, but what is useful to many, that they may be saved (1 Cor. 10:33). Let all say and feel the same — let there be no contentions of mind or disputes. What all the Catholic bishops in the Alexandrian Church have learned as disciples of truth and have taught — let that same faith be professed by all the faithful together: for truth — which is simple and one — receives no variety.

Chapter II: Those Led Astray by Heretics Are to Be Brought Back to Penance With Patience and Gentleness

If any Christians of whatever rank the wicked falsehoods of the heretics have disturbed, summon them to the remedies of satisfaction, and correct them with gentleness in a spirit of patience — since, as the blessed apostle Peter says, the Lord is not slow about his promise, but is patient toward you, not willing that any should perish, but that all should come to repentance (2 Pet. 3:9). The difficulty of obtaining pardon must not make the cure come too late.

Given on the fifteenth day before the Kalends of September, in the consulship of Magnus and Apollonius.

Notes / Historical Commentary

Letter CLXXII, dated August 18, 460, belongs to the coordinated final cluster of the Alexandrian correspondence — written on the same day as Letter CLXXI to the new bishop Timothy and Letter CLXXIII to the bishops of Egypt. It is addressed directly to the Alexandrian presbyters and deacons, not through their bishop. The fact that Leo writes simultaneously to the bishop and to the clergy, each receiving their own letter on the same day, reflects his consistent practice of addressing each level of a local church’s institutional structure separately. He did the same with the Church of Constantinople: Letters CLI and CLV were addressed to Anatolius; Letter CLXI was addressed directly to the Constantinople clergy. The layered approach ensures that no level of the church’s institutional life is left unaddressed, and that the pastoral direction flows from Rome to the whole body, not only through the bishop as sole conduit.

The letter’s two pastoral directions mirror those of Letter CLXXI to Timothy: maintain unity around the new bishop, and approach those who were swept along by the Eutychian occupation with invitation to penance rather than punishment. The second direction is particularly important for the practical work of rebuilding. The Alexandrian community will include many who complied with Aelurus’s regime out of fear, social pressure, or confusion rather than firm doctrinal conviction. Leo does not call for their exclusion; he calls for their summoning — provocate, “summon them,” “call them forward” to the remedies of satisfaction. The word is invitatory, not punitive. The cure must come, but it must not be made so difficult of access that those who need it cannot reach it.

Chapter I’s closing statement — “truth, which is simple and one, receives no variety” — is among the most compressed theological formulations in the entire Leo corpus. It states in a single clause the premise of every canonical ruling and doctrinal intervention Leo has made across his pontificate: the faith is one, simple, and invariant, and therefore what varies from it is not the faith. The Eutychian occupation of Alexandria produced variety where there should have been unity; the restoration of Catholic order restores unity where variety had prevailed. Leo is not simply congratulating the Alexandrian clergy on a political victory; he is reminding them of the theological ground on which Catholic unity stands and from which pastoral reconciliation flows.
