Papal Primacy vs. the Pentarchy
The Petrine Texts: What Scripture Actually Says
The Catholic case for papal primacy begins with a cluster of New Testament texts that, taken together, establish something harder to dismiss than either its defenders or critics usually acknowledge.
In Matthew 16:18–19, Jesus says to Simon Bar-Jonah: “You are Peter [Kepha], and on this rock [kepha] I will build my Church.” The significance of the Aramaic is decisive: Jesus speaks in his native tongue, and kepha is used for both the name and the foundation. This is not the Greek distinction between petros (a small stone) and petra (a bedrock mass) that Protestant polemic once deployed to deny Peter’s role — a distinction Aramaic does not make. The Aramaic makes Jesus’s meaning unmistakable: Simon becomes the Rock on which the Church is built.
The bestowal of “the keys of the kingdom” to Peter alone invokes Isaiah 22:22, where Eliakim son of Hilkiah is appointed royal steward over the house of David — given “the key of the house of David” with authority to open and shut in the king’s name. This is a succession office. When one steward dies, another is appointed. The typological connection between Eliakim and Peter is not eisegesis; it is the standard structure of Davidic kingship theology that any first-century Jewish listener would have heard.
Luke 22:31–32: “Simon, Simon, Satan has asked to sift all of you like wheat. But I have prayed for you, Simon, that your faith may not fail. And when you have turned back, strengthen your brothers.” Jesus prays specifically for Peter’s faith among all the apostles, and commissions him to strengthen the rest. This is not one among equals.
John 21:15–17: After the resurrection, Jesus asks Peter three times “Do you love me?” and each time commissions him: “Feed my lambs… tend my sheep… feed my sheep.” The thrice-repeated commission over the whole flock, corresponding to Peter’s threefold denial, is a reinstatement with explicit pastoral jurisdiction over all.
The name change itself: Jesus renames Simon as Kepha (Rock). No other apostle receives a programmatic name change linked to an ecclesial commission. The act parallels Abraham’s naming and Jacob becoming Israel — both figures who become bearers of a covenant role that extends to their successors.
The Orthodox response to these texts is not to deny Peter’s prominence but to deny its transmissibility. Peter was given a personal charism, not an office that passes to successors in Rome. But this response has a problem: it requires treating the Isaiah 22 typology as if Eliakim’s office were also personal and non-transferable — which the text does not say. It also requires treating “Feed my sheep” as a one-time commission with no ongoing instantiation — despite the fact that someone must feed them after Peter dies.
The Pentarchy: A Sixth-Century Imperial Construction
The Orthodox alternative to papal primacy is typically described as “Pentarchy” — the five ancient patriarchates (Rome, Constantinople, Alexandria, Antioch, Jerusalem) governing the Church collegially, with Rome holding a primacy of honor but not jurisdiction. This model is treated as though it represents the ancient, apostolic constitution of the Church against Rome’s later monarchical claims.
The historical reality is considerably more awkward for that narrative. The Pentarchy as a formal ecclesiological theory does not appear until the Emperor Justinian I codified it in his Novellae of 535 AD — centuries after the apostolic age, and six years before he became the architect of major theological controversies of his own.
Constantinople did not exist until Constantine founded it in 330 AD. Its patriarchate was created not because it held apostolic foundation but because it was, in the words of Canon 3 of Constantinople I (381) and Canon 28 of Chalcedon (451), “the New Rome” — i.e., the imperial city. This is an explicitly political rationale, not a theological one.
Jerusalem was a minor and obscure see. It was elevated to patriarchal status at Chalcedon in 451 primarily on grounds of sentiment — it was the city of Christ’s passion. The canon elevating it acknowledged it had no significant jurisdiction but gave it an honorific place.
After the Islamic conquests of the seventh century, Alexandria, Antioch, and Jerusalem became largely empty sees with tiny, isolated communities. The “Pentarchy” that functioned in practice was a dyarchy of Rome and Constantinople — and it was a dyarchy in constant friction.
If the Orthodox argument against Rome is that papal primacy rests on historical development rather than apostolic institution, the Pentarchy faces the same charge with less scriptural foundation. Peter at least has Matthew 16, Luke 22, and John 21. The Pentarchy has Justinian.
Canon 28 of Chalcedon: What It Says and What Leo Did
Canon 28 of the Council of Chalcedon (451 AD) is the Orthodox proof-text most often cited against papal primacy. It states that Constantinople should hold “equal privileges” to Rome because “it is the city honored by the Emperor and the Senate.” The canon explicitly grounds Constantinople’s dignity in its status as the imperial capital — the same rationale it had used seventy years earlier at Constantinople I.
What is rarely mentioned is what Pope Leo I did.
Leo I — the same pope whose Tome the Council of Chalcedon received with the acclamation “Peter has spoken through Leo” — rejected Canon 28. He refused to ratify it. He insisted that the canon violated the prerogatives Rome held from apostolic institution, not from imperial favor, and that no council could override what Christ had given to Peter.
The significance of the Council’s acclamation is itself remarkable: the assembled bishops were not applauding Leo for clever theology. They were acknowledging that what Peter’s successor had defined was authoritative. The very council that produced Canon 28 simultaneously affirmed that Peter’s voice spoke through the Bishop of Rome.
Furthermore, after the council, the Eastern bishops wrote to Leo begging him to ratify the canons. This presupposed that Leo’s ratification was necessary for the canons to have universal standing — the exact position Catholic ecclesiology defends.
The Orthodox interpretation of Canon 28 faces a significant tension: the council they cite as evidence against Rome also produced the acclamation “Peter has spoken through Leo,” also required Roman approval for its acts to stand, and was also rejected in part by the very pope who defined the Christology the Orthodox accept as definitive. The council cannot be simultaneously authoritative against Rome and irrelevant when it confirms Rome.
The Chrysostom Case: Jurisdiction in Action
One of the clearest pieces of historical evidence for Rome’s jurisdictional role in the first millennium is the case of John Chrysostom, Archbishop of Constantinople, deposed in 404 AD by a politically motivated synod orchestrated by his rival Theophilus of Alexandria.
Chrysostom appealed westward. He wrote simultaneously to three bishops: Innocent I of Rome, Venerius of Milan, and Chromatius of Aquileia. This simultaneous appeal is itself revealing — it suggests that Chrysostom knew the western sees had the standing to act, and he was casting a broad net. But the responses were categorically different.
Venerius of Milan and Chromatius of Aquileia expressed moral solidarity and fraternal sympathy. They wrote letters of support affirming that Chrysostom’s deposition was unjust. That is all they did.
Innocent I of Rome did something categorically different. He declared Chrysostom’s deposition invalid. He refused to recognize Chrysostom’s successors as legitimate bishops. He summoned Theophilus of Alexandria to a Roman tribunal. He convened an Italian synod at which Chrysostom’s deposition was formally condemned. He broke communion with Chrysostom’s successors in Constantinople until Chrysostom was posthumously rehabilitated.
Chrysostom had appealed to all three bishops expecting they could do something. Only Innocent claimed and exercised jurisdiction. Chrysostom’s decision to appeal to Rome at all presupposed that Rome could do what the other sees could not.
The standard Orthodox response is that this represents Roman aggression — Innocent unilaterally asserting authority he was not given. But this interpretation has a problem: Chrysostom appealed to him. You do not appeal to a tribunal you do not believe has authority over your case. Chrysostom anticipated that Innocent could act, and Innocent acted accordingly.
What the Fathers Actually Said About Rome
The patristic record on Roman primacy is more substantial than Orthodox apologetics typically acknowledges — and more complex than Catholic apologetics sometimes presents.
Irenaeus of Lyon (c. 180 AD) argued in Against Heresies III.3 that the Church of Rome holds a “pre-eminent authority” (potentior principalitas) and that all churches must agree with Rome, “for in her the apostolic tradition has been preserved continuously.” This is not merely honorific language; it is a claim about doctrinal normativity.
The Church of Rome wrote to the Church of Corinth to address a local dispute — without being asked, on its own authority, claiming to write “through the Holy Spirit,” and warning of “no small danger” for those who disobey. Corinth had its own bishop. Rome had no geographic claim over Corinth. Yet Rome intervened.
The letter was read liturgically in Corinth for generations afterward (Eusebius reports this). No church reads an intrusive letter from a peer as liturgy. They read it because they received it as authoritative. Irenaeus cited it decades later as an example of Rome’s unique standing.
Cyril wielded Pope Celestine’s formal condemnation of Nestorius as a settled judgment before the Council opened. He did not treat Celestine’s letter as one opinion among equals. He treated it as a declaration that the case was already decided. The Council of Ephesus validated Cyril’s approach by deposing Nestorius on the basis of that condemnation.
The patristic evidence does not support the Catholic reading without qualification. The picture is messy: popes whose authority was sometimes accepted and sometimes contested, councils that sometimes affirmed Roman primacy and sometimes ran roughshod over it, Eastern bishops who appealed to Rome when it suited them and resisted Roman authority when it did not. But this messiness does not support the Orthodox reading either. A purely honorific first place does not explain why Chrysostom expected Innocent to act where Venerius and Chromatius could not. Nor does it explain 1 Clement’s commanding tone, nor Cyril’s use of Celestine’s condemnation as a settlement.
The Ravenna Document: Orthodox Theologians Concede Universal Primacy
In 2007, the Joint International Commission for Theological Dialogue between the Catholic Church and the Orthodox Churches meeting in Ravenna issued an agreed statement that significantly shifted the terms of the debate. The document, signed by Catholic and Orthodox representatives, made three landmark acknowledgments.
First: Both primacy and conciliarity are necessary at every level of the Church — local, regional, and universal. This means Orthodoxy acknowledged that some form of universal primacy is theologically necessary, not merely a Catholic claim.
Second: “In the ancient Church, the Bishop of Rome, as protos among the patriarchs, received appeals from the whole Church, and his see was recognized to have a certain primacy.” The document acknowledged Rome’s historical first place using the Greek term protos — first — and acknowledged Rome as the legitimate recipient of universal appeals.
Third: The remaining question is how this universal primacy is exercised — not whether it exists. The document moved the debate from “does Rome have a universal primacy?” to “what does it look like?”
The Moscow Patriarchate subsequently withdrew from the dialogue process over the Ravenna Document — not because its findings were theologically wrong, but because Constantinople had included the Estonian Apostolic Orthodox Church as a separate delegation, which Moscow disputed. The theological substance of Ravenna was not the issue Moscow objected to.
The Ravenna Document represents a significant Orthodox concession to the Catholic position, made by official Orthodox theological representatives. It does not resolve the question of how universal primacy is exercised, but it removes the ground for the Orthodox claim that Rome’s universal
