The Early Church and Peter's Primacy

Letter CXVIII, from Pope Leo to Bishop Julian of Cos

Synopsis: Leo affirms that he has left nothing undone in defending the faith and the universal Church, distinguishes between the emperor’s duty to repress public disorder and the priestly authority’s duty to deny monks any preaching license, reproves Thalassius of Caesarea for tolerating the monk George’s illicit preaching, and urges Julian to press the emperor to punish without mercy the instigators of the Alexandrian bloodshed.

Leo, bishop, to Julian, Bishop of Cos.

Chapter I: Leo Affirms That Nothing Has Been Omitted in Defending the Faith and the Universal Church

I received your letters, sent through our son the illustrious Esychius, when I had already replied to the renewed occasion of your recent letters. Since you rightly lament these most impious heretics in those words, it was fitting — with the opportunity of writing — not to remain silent. In the cause of the faith, whatever our duty can and must do, with the Lord’s aid, We pursue zealously and gladly, to serve Christ’s Gospel blamelessly — lest any part of the Catholic Church appear neglected through Our sloth. As is widely known, I have not ceased laboring to make manifest and defend the truth of the Lord’s Incarnation — so that all the brotherhood might know what to hold and teach according to apostolic doctrine — with the divinely inspired zeal of the most glorious princes. In the synod of Chalcedon, heretical impiety was condemned, so that no follower of Nestorius or disciple of Eutyches may freely associate with Catholics — since where the authority of the holy council holds, no discord remains.

Chapter II: Priestly Authority Must Deny Monks Any Preaching License; The Emperor Must Punish the Alexandrian Parricides

As it is the duty of imperial power to repress more severely the public tumults and sacrilegious seditions, so it is the authority of the priesthood to deny monks any license to preach against the faith, and to resist with all strength their claiming what pertains to bishops. I marvel that our brother Bishop Thalassius allowed some George — who, by presuming illicitly, has lost both the purpose and the name of a monk — any faculty to write or to preach. If your charity judges it fitting, We will send appropriate letters to that bishop on this matter.

Let your brotherhood act with timely suggestions — urging the most clement prince to command what is pleasing to the Lord, ordering stricter restraint of the instigators of bloody sedition. Neither those whose hands committed crimes nor those who used such madness should go unpunished. If judicial inquiry and the confession of the guilty should reach those whose counsel or impulse drove such evils, no solace of favor should be granted to them. The more that was believed of them, the more detestable is the impiety now revealed — once hidden by hypocrisy. Let the most Christian and most pious emperor act as he knows profits ecclesiastical peace — confident that divine inspiration will guide him both to recall the restless by discipline and to abstain from their blood, though they merit all vengeance for opposing the constitutions both divine and human.

Dated the fourth day before the Nones of April, in the consulship of Opilio, most illustrious man.

Notes / Historical Commentary

Letter CXVIII is a brief operational letter to Julian of Cos, written twelve days after the quadruple March 21 dispatch. It responds to Julian’s most recent reports and deals with two specific matters: the unauthorized preaching of a monk named George under the patronage of Bishop Thalassius of Caesarea, and the need for imperial action against the instigators of the Alexandrian violence.

Chapter II’s two-authority statement deserves the reader’s attention. Leo draws a precise distinction: imperial power represses public disorder; priestly authority governs the boundaries of preaching and clerical office. The monk George has overstepped the bounds of his own order — claiming preaching authority that belongs to bishops — and Thalassius has allowed it. Leo’s response is to propose writing corrective letters to Thalassius, while directing Julian to press the emperor for enforcement of the civil dimensions of the disorder. Neither authority is being asked to absorb the other’s function; each is being directed to exercise its own function in its proper sphere. The two spheres are distinct but their cooperation is essential, and Leo is the coordinator of both.

The Alexandrian dimension of the letter places CXVIII in the broader context of the post-Chalcedon enforcement crisis. The violence in Alexandria — connected with the installation of Timothy Aelurus and the persecution of Proterius’s clergy — represents the same pattern visible in Palestine: the Eutychian party using monastic organization and mob violence to reverse the Chalcedonian settlement on the ground, even after the conciliar and imperial settlement had formally closed the doctrinal question. Leo’s insistence that neither the perpetrators nor those who directed them should receive clemency is a statement about the seriousness with which he views the deliberate subversion of a settlement reached through the full exercise of apostolic and imperial authority.
