The Early Church and Peter's Primacy

Letter XV, from Pope Gelasius to Rusticus, Bishop of Lyon

Synopsis: Pope Gelasius writes to Rusticus, bishop of Lyon, to thank him for the support sent to the Apostolic See amid the persecutions sustained on account of the most impious Acacius — commending Aeonius of Arles for likewise providing assistance, sending Epiphanius of Pavia as legate to the Gallic provinces for the redemption of his captive people, and exhorting Rusticus and his region to continue their devotion not so much to Gelasius as to the Apostolic See itself, since those who are made firm on the rock will be exalted together with the rock.

Pope Gelasius narrates what assistance he has received from Rusticus, bishop of Lyon, and how great the persecutions are which he sustains from Acacius. From the papers of the Reverend Father Hieronymus Vignerius.

To his most beloved brother Rusticus, Gelasius.

Amid the whirlwinds of impending evils and the afflictions of various trials by which we are nearly submerged, your charity, most beloved brother, has supplied us with great consolation. For what could be more consoling than to see most dear brothers compassionate to one another in turn and bearing part of the burden — to whom no small portion of the blessing has been imparted? Blessed be God, who has so disposed your heart toward us, that not only with your mind do you sense what we suffer, but you make this manifest in showing mercy in our holy tribulation, and you join to the sweetest words of consolation those things which are the principal helps among friends.

But we will not weary your beloved person by writing of how greatly we have been straitened. Our brother and fellow bishop Aeonius of Arles knows how useful both what he sent and what you have sent to us has been as a subsidy. As for our brother Epiphanius of Pavia, who is destined for your regions to lift up his people and to redeem captives, [he] will inform your brotherhood how great a persecution we sustain on account of the most impious Acacius. But we do not fail; and amid so many pressures neither does our spirit yield, nor does our zeal slacken, nor does fear overturn us. Yet, although we are anxious and straitened, we trust in him who will give the outcome with the temptation; and if he allows us to be cast down for a time, he will not allow us to be utterly oppressed.

See to it, dearest brother, that the affection of you and yours toward us — or rather, toward the Apostolic See — does not cease. For those who shall be made firm on the rock shall be exalted together with the rock.

Help our brother Epiphanius, and let him perceive that you love me; and when he returns to his own [region], let your beloved person write both what may seem [right] to himself and what may seem [right] to our brothers and fellow bishops established throughout the Gauls concerning the cause of the most impious Acacius. May God preserve you safe, dearest brother.

Given on the eighth day before the Kalends of February, in the consulship of the most distinguished men Asterius and Praesidius (in the year of Christ 494).

Notes / Historical Commentary

Letter XV to Rusticus of Lyon is dated January 25, 494, placing it in the early part of Gelasius’s pontificate (492–496) and in the active middle of the Acacian Schism. The letter is short, personal, and warm in tone — but its theological substance, especially in the closing Petrine formula, makes it one of the more important documents of the Gelasian corpus for the question of papal primacy.

The historical setting is precise. Rome had been in formal schism with Constantinople since Pope Felix III’s excommunication of the patriarch Acacius in 484. Acacius had died in 489 still under sentence, but the schism had not been resolved; the Eastern court continued to press Rome to relax the excommunication, and Italian and Gallic bishops were being approached, both through diplomacy and through other pressures, to encourage them toward neutrality or sympathy with Constantinople. Gelasius’s pontificate was largely consumed with maintaining the Roman stand and preventing the slow erosion of the unity of the western episcopate around the Apostolic See. The reader who works through the Gelasian corpus will see this concern again and again: the firm refusal to relax the Acacian condemnation (as in the Decreta to the bishops of Dardania), the careful pastoral support given to bishops who held firm with Rome, the legates dispatched to gather and confirm the unity of the Gallic and Italian episcopates, and the doctrinal and disciplinary letters that articulate the principles at stake.

Rusticus of Lyon, the recipient of this letter, was a key figure in that western coordination. As metropolitan of Lugdunensis Prima he had jurisdiction over a substantial province; Lyon was a major communications hub for Roman correspondence with Gaul. The two other bishops named in the letter — Aeonius of Arles and Epiphanius of Pavia — fill out the picture of how Rome operated through this period. Aeonius held the Roman vicariate over southern Gaul, the same arrangement Leo I had developed for Illyricum through Anastasius of Thessalonica and extended elsewhere; Roman directives reached the southern Gallic provinces through Aeonius’s vicariate. Epiphanius of Pavia, the famous redeemer of captives whose Vita by Ennodius is one of the most vivid hagiographies of the period, was Gelasius’s chosen legate to the Gallic churches — combining his pastoral mission (the redemption of his captive people, presumably from the Burgundian incursions) with the diplomatic mission of communicating Rome’s position on the Acacian cause and gathering the Gallic episcopate’s response.

The doctrinal heart of the letter is the closing Petrine formula. Gelasius’s correction of Rusticus’s address — that the affection should be directed not so much to Gelasius personally as to the Apostolic See — is one of the clearest patristic statements of the structural distinction between the personal occupant of the see and the see itself. The Roman pope is not asking for personal loyalty; he is asking for adherence to the See of Peter, of which he is the present bearer. The doctrinal point is precise: the prerogative of the see is permanent and structural; the occupant exercises that prerogative as its current bearer; loyalty to the bishop and loyalty to the see are the same act, but they are conceptually distinct. Leo I had articulated the same distinction in his anniversary sermons on his consecration, when he said nostrum est officium, sed Petri auctoritas (“ours is the office, but the authority is Peter’s”). Gelasius here applies the principle to a different question — material and fraternal support during persecution — and produces the same structural insight.

The formula Qui enim in petra solidabuntur cum petra exaltabuntur — “for those who shall be made firm on the rock shall be exalted together with the rock” — deserves particular attention as one of the most compressed and powerful Petrine statements in the Gelasian corpus. It is not a Scriptural citation but a Gelasian formulation built on Matt. 16:18, working through the patristic identification of Peter as the rock through which the Roman see participates in the firmness of Christ. The doctrine compressed into the sentence is double: those who stand with Rome in the present persecutions partake in the firmness of the rock now, and they will share in the eschatological exaltation of the rock when the rock is itself exalted. Suffering with the Apostolic See is participation in the standing and the future glory of the see. This is the same Petrine ecclesiology that runs through the entire Roman corpus from Leo through Gelasius and on to Hormisdas — and the formula here is one of its most pithy expressions.

The closing request — that Rusticus, after Epiphanius’s return, gather and report back the views of the Gallic episcopate on the Acacian cause — closes the letter on a structural note. Rome maintains its position not by isolated assertion but through coordinated communication with the western churches, gathering their views, confirming or correcting them, and bringing them into the unity of the Roman position. The pattern is the institutional expression of the Roman bishop’s sollicitudo for all the Churches: not arrogant centralization but constant working communication, in which the local bishops are full participants in the discernment of the Catholic faith under the Roman bishop’s structural responsibility. Rusticus is being enlisted as one node in that network of coordination — and the letter’s closing assumes, without argument, that this is the proper functioning of the western episcopate under the Apostolic See.
