Pope Saint Eleutherius: The Thirteenth Pope, the Martyrs of Lyons, and the Legend of a British King

The thirteenth in a series on the popes.

Every pope in this series since Peter has entered the record only at the moment he took office—a name appearing at the top of a list, with nothing before it. Eleutherius is the first exception. Before he was pope he was a deacon, and we know it from a man who knew the Roman church while he served in it. That small fact—a documented career before the papacy—makes the thirteenth pope a milestone of a quiet kind: with him, the popes stop being names and start being men with histories. It is one of history’s small ironies that the same pope should also carry the most extravagant fiction attached to any early bishop of Rome, a legend in which he baptizes Britain by mail. The historical Eleutherius sits between those poles: a real churchman with a real career, remembered by the men who dealt with him, and buried afterward under a millennium of legend.

This is the thirteenth entry in my series on the popes, following Peter, Linus, Anacletus, Clement, Evaristus, Alexander I, Sixtus I, Telesphorus, Hyginus, Pius I, Anicetus, and Soter. As with his predecessors, the work is to separate what the second century actually tells us—which for Eleutherius is more than usual—from what later centuries wished it had.

The Deacon of Anicetus

The best evidence for Eleutherius comes from before his pontificate, and it is the kind of evidence historians prize most: an eyewitness aside, dropped in passing, with no argumentative agenda. Hegesippus, the traveling chronicler whose memoirs Eusebius excerpts, described his long stay in Rome in the middle of the century with this remark: “And when I had come to Rome I remained there until Anicetus, whose deacon was Eleutherus. And Anicetus was succeeded by Soter, and he by Eleutherus.”⁠¹

“Whose deacon was Eleutherus.” Hegesippus is not making a point about Eleutherius at all; he is dating his own visit, and the deacon’s name is furniture. That is precisely what makes it valuable. A generation before his election, Eleutherius was already a known officer of the Roman church, prominent enough that a visiting writer could use him as a chronological landmark. When his turn came—after Anicetus’s reign, and Soter’s—the church of Rome elevated a man who had served it in senior office for some two decades. However the mid-second-century Roman church chose its bishop, it did not choose a stranger.

The detail rewards one further thought. The diaconate of the early Roman church was no ceremonial office; deacons managed the church’s money and its charity—the very charity that, under Soter, Dionysius of Corinth praised Rome for extending “to many churches in every city.” If Eleutherius served as deacon under Anicetus and (presumably) remained a senior figure under Soter, then the future pope spent his formative years administering exactly the system of organized generosity that made Rome’s reputation abroad. The thirteenth pope was formed in the counting-house of Roman charity.

His name, for what it is worth, is Greek—Eleutherios, “the free one”—and the Liber Pontificalis makes him a Greek from Nicopolis in Epirus. Eamon Duffy glosses the name as “freedman,” which slightly overstates the etymology (the technical Greek term for a freed slave was apeleutheros), but his underlying point stands: names of this family were characteristic of the slave and freedman milieu from which the Roman church drew so many of its members, and a Greek-speaking easterner rising through the Roman clergy fits everything we know about that church’s composition.⁠²

The List That Ends with Him

Eleutherius holds a distinction no other pope in this series can claim: the most consequential Christian book of the second century was written under him, about—among much else—the line of bishops that ended with him. Irenaeus of Lyons, writing Adversus Haereses (Against Heresies) around 180, set out the Roman succession as his public, checkable argument against the Gnostic claim to secret tradition, and brought the list down to the present moment:

Soter having succeeded Anicetus, Eleutherius does now, in the twelfth place from the apostles, hold the inheritance of the episcopate. In this order, and by this succession, the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us.⁠³

“Does now hold”: the present tense is the historian’s gift. It dates the third book of Against Heresies to Eleutherius’s reign with a precision almost nothing else in second-century literature allows, and it means the Church’s foundational statement of apostolic succession—the argument this series has leaned on in every entry—was composed with Eleutherius as its living endpoint. Whatever else his pontificate accomplished, it presided over the moment when the Roman succession list passed from memory into literature.

The number, as always, depends on the counting. Irenaeus reckons from Linus, with Peter at the head of the line as its founder; on that count Eleutherius stands twelfth—and Eusebius adopts the same figure, calling him “the twelfth from the apostles.” Counting Peter himself as the first pope, as the modern convention does and as this series does, Eleutherius is the thirteenth. Two arithmetics, one unbroken line.⁠⁴

The Dates We Cannot Quite Fix

Eusebius opens his fifth book with the succession notice: “Soter, bishop of the church of Rome, died after an episcopate of eight years, and was succeeded by Eleutherus, the twelfth from the apostles. In the seventeenth year of the Emperor Antoninus Verus”—that is, Marcus Aurelius, in 177—“the persecution of our people was rekindled more fiercely in certain districts.”⁠⁵ Strictly, the seventeenth year dates the persecution of Lyons, which Eusebius is about to narrate; but the year-notice follows hard on the succession notice, and the two events are evidently close. The end of the reign is the most secure date in this whole stretch of papal history: “In the tenth year of the reign of Commodus”—189—“Victor succeeded Eleutherus, the latter having held the episcopate for thirteen years.”⁠⁶

Thirteen years back from 189 lands the accession at 176 or 177, a year or so later than the conventional c. 175; the difference is the usual slippage between Eusebius’s arithmetic and the chronicle tradition, and nothing turns on it. The Liber Pontificalis gives him fifteen years and change, a Greek nationality, a father named Habundius, and a hometown of Nicopolis—the city at the mouth of the Gulf of Arta in Epirus—along with a consular date that contradicts its own reign length. The safe summary: Eleutherius governed the Roman church from the mid-170s until 189, a long reign by the standards of the age, and died in the same year Commodus’s decade of misrule reached its final phase.⁠⁷

The Blood of Lyons

The defining public event of Eleutherius’s reign happened six hundred miles from Rome. In the summer of 177, the Greek-speaking Christian communities of Lyons and Vienne in Gaul were destroyed by a persecution of exceptional savagery—mob violence hardening into judicial process, the aged bishop Pothinus dying in prison, the slave girl Blandina tortured through days of spectacle in the amphitheater. The survivors’ own account, preserved by Eusebius, is among the most affecting documents early Christianity produced; it lies beyond this entry’s scope, but its aftermath does not. For the confessors awaiting death in prison did something remarkable: they wrote letters—and one of the addresses was Rome.

Eusebius records it in his catalogue of the church of Lyons’s correspondence concerning the new Phrygian movement: the Gallic brethren “set forth their own prudent and most orthodox judgment in the matter, and published also several epistles from the witnesses that had been put to death among them. These they sent, while they were still in prison, to the brethren throughout Asia and Phrygia, and also to Eleutherus, who was then bishop of Rome, negotiating for the peace of the churches.”⁠⁸

That last clause deserves its emphasis. Men under sentence of death, in a provincial prison in Gaul, spent some of their remaining hours writing to the bishop of Rome—“negotiating for the peace of the churches.” Whatever theory of Roman authority did or did not exist in 177, the practice is visible: when the churches of the Rhône valley feared a rupture in the universal Church, the address they wrote to, alongside the churches of the movement’s homeland, was Rome’s.

And they chose their courier with care. Eusebius continues: “The same witnesses also recommended Irenaeus, who was already at that time a presbyter of the parish of Lyons, to the above-mentioned bishop of Rome, saying many favorable things in regard to him, as the following extract shows”:

We pray, father Eleutherus, that you may rejoice in God in all things and always. We have requested our brother and comrade Irenaeus to carry this letter to you, and we ask you to hold him in esteem, as zealous for the covenant of Christ. For if we thought that office could confer righteousness upon any one, we should commend him among the first as a presbyter of the church, which is his position.⁠⁹

“Father Eleutherus.” The martyrs of Lyons, writing from prison, address the bishop of Rome as father—apparently the earliest such address to a pope to survive in a contemporary document. And the courier they commend “as zealous for the covenant of Christ” is Irenaeus himself: the future bishop of Lyons, the future author of Against Heresies, carrying his first known commission—a letter of introduction to the pope. The embassy evidently made an impression on both parties. Irenaeus returned to Gaul to succeed the martyred Pothinus as bishop; and when he came to write his great book a few years later, the church “founded and organized at Rome by the two most glorious apostles” stood at the center of his argument, with Eleutherius’s name at the end of its list.

The New Prophecy

What the Lyons letters were about is the crisis that shadowed the rest of the century. At some point between the mid-150s and the early 170s—the ancient datings themselves disagree—a Phrygian convert named Montanus began to prophesy in ecstasy, joined by two prophetesses, Prisca and Maximilla, announcing the outpouring of the Paraclete and a regime of new rigor: fasts multiplied, remarriage forbidden, martyrdom courted. The movement called itself the New Prophecy; its enemies called it the Phrygian heresy; history calls it Montanism. It was not, at first blush, a heresy at all in the doctrinal sense—Montanists confessed the same creed—and that is what made it so difficult. The question it posed was one of authority: does the Spirit still speak through new prophets, over the heads of the bishops? The churches of Asia Minor convulsed over it; the churches of Gaul, Phrygian in their connections, felt it immediately; and their martyrs’ letters urged their “prudent and most orthodox judgment” on Rome precisely because Rome’s decision would matter beyond Rome.⁠¹⁰

What did Eleutherius decide? Here the honest answer is that we do not know, and the one text that seems to tell us refuses to name its subject. Tertullian—writing decades later as a Montanist partisan—opens his attack on the heretic Praxeas with a story from Rome:

For after the Bishop of Rome had acknowledged the prophetic gifts of Montanus, Prisca, and Maximilla, and, in consequence of the acknowledgment, had bestowed his peace on the churches of Asia and Phrygia, he, by importunately urging false accusations against the prophets themselves and their churches, and insisting on the authority of the bishop’s predecessors in the see, compelled him to recall the pacific letter which he had issued, as well as to desist from his purpose of acknowledging the said gifts. By this Praxeas did a twofold service for the devil at Rome: he drove away prophecy, and he brought in heresy; he put to flight the Paraclete, and he crucified the Father.⁠¹¹

A bishop of Rome, then, at some point acknowledged the Montanist prophecies, issued letters of peace to the churches of Asia and Phrygia—and then, persuaded by Praxeas “insisting on the authority of the bishop’s predecessors,” withdrew them. Which bishop? Tertullian does not say, and scholarship has never settled it. The old Catholic Encyclopedia inclined to Eleutherius, imagining him hesitating long over a movement whose “peculiar nature made it difficult to take from the outset a decisive stand”; the American editors of the Ante-Nicene Fathers printed “probably Victor” in their note to the passage; and a case has been made for Zephyrinus as well. The pope in question probably belongs to this entry or one of the next two, and honesty requires leaving it there.⁠¹² Nor is it certain what the Gallic confessors advised. Eusebius calls their judgment “prudent and most orthodox” but declines to quote it; the standard reading is that they disapproved of the prophets while pleading against extreme measures, though some older scholars read the correspondence as urging toleration outright. What is certain is only this: under Eleutherius, the Roman church became the clearinghouse for the Montanist question—the Gallic confessors’ appeal is documented, and Tertullian’s notice implies Phrygian overtures as well—and its final condemnation of the movement did not come in his reign.

The episode is a useful corrective to tidy narratives in both directions. Against the maximalist, it shows a Roman church feeling its way—capable of issuing letters of peace and then recalling them, swayed by visiting personalities, hesitating for years over a movement the whole Church was watching. Against the minimalist, it shows why the hesitation mattered: everyone involved—Phrygian enthusiasts, Gallic confessors, the trouble-making Praxeas—behaved as though the Roman bishop’s letters of peace or condemnation settled something well beyond the city of Rome. A church with no wider standing has no letters worth intriguing over.

The Decree About Food

The Liber Pontificalis attributes to Eleutherius one decree: “that no kind of food in common use should be rejected especially by the Christian faithful, inasmuch as God created it; provided, however, it were rational food and fit for human kind.”⁠¹³ Unlike the chronicle’s usual liturgical anachronisms, this one at least addresses a genuinely ancient issue—the rejection of foods as unclean was a live question from the apostolic age onward, and Paul had already answered it in Romans 14. But that is precisely the problem: the decree restates a position as old as the New Testament, and Loomis suggests the chronicler was actually aiming at the food-asceticism of the Manicheans, “of which much was heard in Rome in the fifth century.”⁠¹⁴ A sixth-century compiler, facing fifth-century ascetics, put a timeless answer in a second-century mouth. As history of Eleutherius’s reign it is worthless; as a specimen of how the Liber Pontificalis manufactures papal decrees, it is nearly perfect.

The King Who Wasn’t There

And then there is Lucius. The Liber Pontificalis entry contains one sentence that would echo for a millennium: “He received a letter from Lucius, king of Britain, asking him to appoint a way by which Lucius might become a Christian.”⁠¹⁵

Every word of that sentence dissolves under examination. Second-century Britain was a Roman province garrisoned by three legions; it had tribal client-chiefs under Roman supervision, but no “king of Britain” existed to write to anyone, and no British source, Roman source, or Christian source before this sixth-century Roman chronicle knows anything of one converting. Loomis’s footnote states the situation exactly: “The source of or ground for this extraordinary statement is quite unknown. It appears first here in the Lib. Pont. Bede and other medieval English chroniclers built up considerable legend upon it.”⁠¹⁶

Built they did. The Venerable Bede, taking the notice from the Liber Pontificalis around 731, gave it the authority of England’s greatest historian: “Lucius, king of Britain, sent a letter to him, entreating that by a mandate from him he might be made a Christian. He soon obtained his pious request, and the Britons preserved the faith, which they had received, uncorrupted and entire, in peace and tranquillity until the time of the Emperor Diocletian.”⁠¹⁷ Four centuries later Geoffrey of Monmouth inflated the sentence into a full royal saga: King Lucius writes to Eleutherius; the pope dispatches the missionaries Faganus and Duvianus; the whole island converts; the pagan flamens become bishops in their sees. By the Reformation, the legend had become a weapon both sides reached for—Catholics citing it to prove England’s faith came from Rome, Protestants citing it to prove a British Christianity older than Roman obedience. A brass tablet in the church of St. Peter upon Cornhill in London still asserts that King Lucius founded it in AD 179.⁠¹⁸

Where did the sentence come from? The most influential modern answer was proposed by Adolf von Harnack in 1904. In the source the chronicler drew on, he argued, the name was not Britanio but Britio—and Britium (Birtha) was the citadel of Edessa in Syria, whose king, Lucius Aelius Aurelius Septimius Megas Abgar VIII, was precisely a late-second-century monarch remembered as a Christian. A scribe’s eye turned Britio into Brittanio, and a Syrian king became a British one.⁠¹⁹ The conjecture is elegant, it has held the field for over a century, and standard reference works still repeat it as the probable solution. It should nonetheless be reported as a conjecture, because it has been seriously challenged: Abgar is nowhere called “king of Britium” in contemporary sources—one does not reign over a citadel—and his Roman names postdate the period his conversion legend describes. A recent book-length treatment argues the emendation fails and the legend’s origin must be sought elsewhere.⁠²⁰ The honest summary: the Lucius sentence is unhistorical as it stands; Harnack’s Edessa solution is the reigning guess at how it arose; and the guess remains a guess. What is not in doubt is that the historical Eleutherius received no letter from a king of Britain, and sent no missionaries to convert one.

The Martyrdom That Isn’t There

The pattern will be familiar from the last several entries, and for Eleutherius the case is even simpler: not even the Liber Pontificalis claims he died a martyr. Its entry gives him a burial “near the body of the blessed Peter in the Vatican” and a date of death; the martyr title appears only in the later liturgical books, which styled nearly every early pope a martyr as a matter of course. No early source records any violence against him, and his reign—persecution in Gaul notwithstanding—fell in a period when the Roman church itself was left largely in peace. The pre-1970 calendar commemorated him on 26 May as “pope and martyr”; the current Martyrologium Romanum keeps the day and drops the title, remembering him instead—in another fine touch of the modern martyrology—as the pope to whom the martyrs of Lyons wrote their letter “on maintaining the peace of the Church.”⁠²¹ The men who actually shed their blood in his reign now supply the one line of his official commemoration. He would have no grounds for complaint.

What We Can Actually Say

Strip Eleutherius to the load-bearing evidence and a career emerges—the first real career in papal history. A Greek-speaking churchman, deacon of the Roman church under Anicetus in the 150s, attested in that office by a contemporary who lived in Rome; elected bishop after Soter in the mid-170s; reigning thirteen years until 189. In his reign the martyrs of Lyons wrote to him from prison as “father Eleutherus,” seeking the peace of the churches in the Montanist crisis, and sent as their courier the presbyter Irenaeus, who would shortly write the century’s greatest theological work and close its Roman succession list with Eleutherius’s name. Rome under Eleutherius was the address to which Gaul and Phrygia alike directed the era’s hardest question of church authority—even if his own answer to it, assuming Tertullian’s unnamed hesitating bishop is he, was to feel his way and finally leave the condemnation to his successors.

What the evidence does not support is the rest: the food decree (a later controversy retrojected), the martyrdom (claimed by no early source, dropped by the modern calendar), and above all the British king—the most successful fiction ever attached to an early pope, born of a sixth-century sentence of unknown origin, canonized by Bede, inflated by Geoffrey, weaponized by the Reformation, and still defended on a brass tablet in a London church. The historical man needs none of it. The deacon who became pope, the father to whom martyrs wrote, the endpoint of Irenaeus’s list: that is standing enough.

Next in the series: Pope Saint Victor I, the African pope who took the Easter question Anicetus had left in peace—and issued an ultimatum to the churches of Asia.

Frequently Asked Questions

Who was Pope Saint Eleutherius?

Eleutherius was the thirteenth Bishop of Rome counting Peter as first, conventionally dated c. 175–189. He is the first pope after Peter with a documented earlier career: the chronicler Hegesippus, who lived in Rome in the mid-second century, records that Eleutherius served as deacon under Pope Anicetus, two reigns before his own election. His pontificate saw the persecution of Lyons (177), whose imprisoned confessors wrote to him about the Montanist crisis and commended to him their courier, the presbyter Irenaeus—the future author of Against Heresies, whose famous list of Roman bishops ends with Eleutherius.

When did Eleutherius reign as pope?

From the mid-170s to 189. Eusebius places his accession after Soter’s eight-year reign and gives him thirteen years; the end is fixed by the most secure date in early papal chronology—Victor’s succession “in the tenth year of the reign of Commodus,” 189. Counting back thirteen years yields an accession around 176/7; the conventional date c. 175 reflects the usual slippage among the ancient chronologies.

Did King Lucius of Britain really write to Pope Eleutherius?

No. The story first appears in the sixth-century Liber Pontificalis—“He received a letter from Lucius, king of Britain, asking him to appoint a way by which Lucius might become a Christian”—and no earlier British, Roman, or Christian source knows anything of it; second-century Britain was a Roman province with no king. Bede adopted the notice, Geoffrey of Monmouth inflated it into a full conversion saga, and both Reformation sides later weaponized it. The most influential modern explanation, Harnack’s 1904 conjecture that a scribe misread “Britio” (the citadel of Edessa, whose king Abgar VIII was a Christian) as “Britannio,” remains the standard account of the error, though it has been seriously challenged in recent scholarship.

What was Pope Eleutherius’s connection to the martyrs of Lyons?

In 177, during the savage persecution of the churches of Lyons and Vienne, the imprisoned confessors wrote letters concerning the Montanist controversy—to the churches of Asia and Phrygia, and to Eleutherius in Rome, “negotiating for the peace of the churches.” They addressed him as “father Eleutherus” and commended their letter-carrier, the presbyter Irenaeus, as “zealous for the covenant of Christ.” It is apparently the earliest surviving document in which a pope is addressed as “father,” and it launched the career of the century’s greatest theologian.

How did Rome respond to Montanism under Eleutherius?

We do not know with certainty. Tertullian reports that a bishop of Rome initially acknowledged the Montanist prophecies and issued “letters of peace” to the churches of Asia and Phrygia, then revoked them under the influence of Praxeas—but he never names the bishop, and scholars have variously identified him as Eleutherius, Victor, or Zephyrinus. What is clear is that under Eleutherius Rome became a clearinghouse for the question—the appeal of the Gallic confessors is documented, and Tertullian’s notice implies Phrygian approaches as well, and that the definitive Roman condemnation of Montanism came only after his reign.

Was Eleutherius a martyr?

There is no evidence for it—and in his case, not even the Liber Pontificalis makes the claim. The chronicle records only his burial near the body of Peter in the Vatican. The martyr title was attached by later liturgical books, which styled nearly all early popes martyrs indiscriminately. The current Martyrologium Romanum commemorates him on 26 May without the title, remembering him as the pope to whom the martyrs of Lyons wrote on preserving the Church’s peace.
