The Early Church and Peter's Primacy

Letter V, from Pope Gelasius to Honorius, Bishop of Dalmatia

Synopsis: Gelasius writes to Honorius of Dalmatia warning that the Pelagian heresy, long condemned by the Apostolic See through Innocent, Zosimus, Boniface, Celestine, Sixtus, and Leo, is resurfacing in the Dalmatian regions, grounding his intervention in the care delegated to Peter by the Savior’s own voice and in the solicitude he cannot dissemble, and directing that what the Fathers have once condemned must not be reopened for examination.

Gelasius to his most beloved brother Honorius.

The Care Delegated to Peter by the Savior’s Own Voice; The Solicitude That Cannot Be Dissembled

Although we are entangled in the continual occupations of various difficulties of the times and can scarcely draw breath, nevertheless, exercising the governance of the Apostolic See and treating without ceasing the care of the whole flock of the Lord — which was delegated to blessed Peter by the voice of our Savior Himself: And you, when you have turned, confirm your brothers (Luke 22:32); and likewise: Peter, do you love me? Feed my sheep (John 21:17) — We cannot dissemble or neglect what the form of Our solicitude demands, feeling and speaking with the blessed Apostle Paul: Who is weak, and I am not weak? Who is scandalized, and I am not on fire? (2 Cor. 11:29).

For so suddenly has a grievous, dreadful, and scarcely credible report struck us as to confound, wound, and afflict Our mind. It has been reported to us that in the regions of Dalmatia certain persons have been sowing the weeds of the recurring Pelagian pestilence, and that their blasphemy prevails there to such an extent that they deceive all the simple by the insinuation of their deadly fury. This error is indeed all the more dangerously insidious in its assault, the more craftily it employs the color of plausibility to deceive. But by the Lord’s help, the pure truth of the Catholic faith is at hand, drawn from the harmonious judgments of all the Fathers, which both exposes the subtle poison of this deadly depravity and provides from the composition of the Scriptures a remedy for the salvation of the human race.

Therefore let not the abundance of undiscerning hearts be disturbed, until both the hidden wound appears and the singular salvation shines forth — for by whatever art the spirit of perdition arms its deception, it is both uncovered and slain by the holy sword of the principal Spirit. Wherefore, through your charity, We admonish all the priests of the Lord there with fraternal affection: that, since with the Lord teaching you, you fight against novel errors, you must not receive a perversity long since condemned throughout the whole world, nor suppose that what is rashly thought should be done — that a heresy fitly extinguished by our forebears should dare to provoke us again and openly take the field with renewed forces.

What the Fathers Have Defined May Not Be Reopened; The Boundaries of the Fathers Must Not Be Transgressed

Is it permitted to us to dissolve what has been condemned by the venerable Fathers, and to reopen the wicked doctrines they cut away? What, then, is the great precaution we take, lest the destructiveness of any heresy once overthrown seek to come again to examination? If we strive to restore what was long ago known, discussed, and refuted by our forebears, do we not ourselves — God forbid, and may the Catholic Church never tolerate it — set before all the adversaries of truth the example of rising again against us? Where is what is written: Do not transgress the boundaries of your fathers (Prov. 22:28)? And: Ask your fathers, and they will tell you; your elders, and they will teach you (Deut. 32:7)? Why, then, do we reach beyond the definitions of our forebears, and why do they not suffice for us? If there is something we wish to learn in our ignorance, let us learn how each matter was judged by the orthodox Fathers and elders — what must be avoided and what must be adapted to Catholic truth. Why are their decrees not accepted as proof?

The Chain of Predecessors: Innocent, Zosimus, Boniface, Celestine, Sixtus, and Leo Condemned This Heresy by Continuous and Unceasing Sentences

Are we wiser than they, or can we stand with firm stability if we undermine what they established? Or do you perhaps not know that this heresy of which we speak was long ago struck down by the Apostolic See through Innocent of blessed memory, and then Zosimus, Boniface, Celestine, Sixtus, and Leo, by continuous and unceasing sentences — and not only by the laws of the Catholic Church, but also condemned by the Roman princes with such severity that its followers were not permitted to have a place to live anywhere in the world? All of this is taught both by the acts of the Church conducted in every region where their depravity spread, and by the sanctions of public law.

See how Catholic ears can hear their doctrine, receive their arguments, consider their snares, and patiently entertain their blasphemies! If only they would study the books and responses of our forebears written against them — there it would be seen by every means that there is absolutely nothing that was not already examined by them and crushed by the magnificent truth. And so all the faithful would be so instructed in refuting all their wickedness that nothing more would need to be sought. But if perhaps certain of their propositions should disturb untrained minds, the teachings of the venerable Fathers both expose all their madness and show by what remedies it may be cured — so that, with God’s help providing foresight, all that they have woven together may be seen to be both dangerous for those who follow them and foolish for those who examine them. So that even if anyone thinks resistance is necessary, he need not set himself up as an opponent of the judgments of the ancients, but would openly profess himself an enemy of human salvation and Catholic teaching.

The Shepherd Must Drive the Wolves from the Sacred Flocks

All the more attentively must the watchful care of pastors drive the savagery of wolves from the sacred flocks. For whatever harm befalls the holy sheep condemns — God forbid — the negligence of the bishops; just as the expulsion of harmful beasts from the regenerated flocks has procured perpetual increase as the reward of faithful guardians. Certainly, if — as we rather hope — these things have been reported on the basis of false rumors, we desire to learn of it as quickly as possible, so that we who tremble at the affliction of Christ’s members may rejoice all the more at their stability.

Notes / Historical Commentary

Letter V shifts the Gelasius corpus from the Acacian schism to a different front: the resurgence of the Pelagian heresy in the Dalmatian provinces. The subject is doctrinal rather than jurisdictional, but the letter’s framing is a concentrated statement of the same Petrine ecclesiology that governs the Eastern correspondence. The reader should not pass over this framing to get to the Pelagian content, because the framing is itself one of the most important primacy passages in the corpus.

The opening sentence is remarkable for its density. Gelasius names three converging elements: the governance of the Apostolic See (moderamen), the care of the whole flock of the Lord (cura totius ovilis dominici), and the delegation of this care to Peter by the voice of Christ Himself (Salvatoris ipsius nostri voce delegata). Two scriptural commissions are cited — Luke 22:32 (“confirm your brothers”) and John 21:17 (“feed my sheep”) — and the sollicitudo formula immediately follows: Gelasius cannot dissemble or neglect what the form of his solicitude demands. This is structurally identical to Leo’s treatment of the same theme: the pope writes to a distant church not because he chooses to but because the Petrine commission requires it. The solicitude is not optional; it is the form of the office.

The chain of predecessors who condemned Pelagianism is the letter’s most significant datum for the continuity argument. Gelasius names six popes — Innocent, Zosimus, Boniface, Celestine, Sixtus, and Leo — spanning nearly a century of continuous condemnation. The phrase continuis et incessabilibus sententiis — “by continuous and unceasing sentences” — makes the point explicit: this is not six independent judgments but one continuous exercise of the Apostolic See’s authority, maintained without interruption across successive pontificates. After Leo, the chain continues implicitly through Hilarius, Simplicius, Felix III, and now Gelasius himself. The argument is that what the Apostolic See condemns stays condemned, and the condemnation is not the act of any individual pope but of the See itself operating through its successive occupants.

The principle that what the Fathers have defined may not be reopened for examination is stated with particular force. Gelasius frames the reopening of settled questions as itself an act of betrayal — setting before all the adversaries of truth an example of rising again. The boundaries of the fathers must not be transgressed. This principle, applied here to Pelagianism, is structurally identical to the principle Gelasius applies to the Acacian question in Letters I and IV: the Apostolic See’s condemnation is final, and to reopen it is not to seek truth but to undermine the authority that settled the question.
