St. Irenaeus on the Unity and Orthodoxy of the Faith

St. Irenaeus

St. Irenaeus.

Today is the feast day of St. Irenaeus of Lyons (or Lugdunum, by its Roman name). Irenaeus was born in the first half of the second century, ca. A.D. 125, probably in Smyrna in Asia Minor. He was raised in a Christian home, and became a disciple of St. Polycarp, who had been a disciple of St. John the Apostle. After missionaries had begun to convert the Gauls of the West, Irenaeus journeyed to become a priest in Lugdunum, and later bishop. He suffered martyrdom at the beginning of the third century.

In his life, St. Irenaeus was an ardent opponent of Gnosticism, one of the earliest and most major Christian heresies, which was becoming rampant in his time. The Gnostics argued that they had received a secret oral tradition showing the way to Gnosis, hidden knowledge as a means to save the soul from the material world. It marked a blending of Christianity with elements of Hellenistic and Persian spirituality. Most of the so-called “lost books” of the New Testament were Gnostic texts rejected by the orthodox Church.

Irenaeus’s best known work, Adversus haereses or Against Heresies, written ca. 180, is a lengthy and detailed attack on Gnosticism and defense of the orthodox Christian faith. We find in it an important early witness to Christian orthodoxy: a statement of the core truths we hold central to the Christian faith today, intact and fully realized. Irenaeus argues strongly for the doctrine of apostolic succession: that the only way to ensure the orthodoxy, integrity, and fullness of the faith — to ensure that no heretical doctrines or corruptions crept in — is for Christian faith and teachings to be passed down through a known succession of bishops, whose line could be traced back to the Apostles themselves. The Gnostics had no such claim to apostolic authority, and by this he rejected their arguments.

Here I’ll quote a few important passages:

The Church, though dispersed through our the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith: [She believes] in one God, the Father Almighty, Maker of heaven, and earth, and the sea, and all things that are in them; and in one Christ Jesus, the Son of God, who became incarnate for our salvation; and in the Holy Spirit, who proclaimed through the prophets the dispensations of God, and the advents, and the birth from a virgin, and the passion, and the resurrection from the dead, and the ascension into heaven in the flesh of the beloved Christ Jesus, our Lord, and His [future] manifestation from heaven in the glory of the Father to gather all things in one (Ephesians 1:10), and to raise up anew all flesh of the whole human race, in order that to Christ Jesus, our Lord, and God, and Saviour, and King, according to the will of the invisible Father, every knee should bow, of things in heaven, and things in earth, and things under the earth, and that every tongue should confess (Philippians 2:10-11) to Him, and that He should execute just judgment towards all . . . (Against Heresies I.10.1)

Irenaeus’s “rule of faith” bears many resemblances to the Apostles’ Creed, and is an early declaration of Christian orthodoxy.

As I have already observed, the Church, having received this preaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it. She also believes these points [of doctrine] just as if she had but one soul, and one and the same heart, and she proclaims them, and teaches them, and hands them down, with perfect harmony, as if she possessed only one mouth. For, although the languages of the world are dissimilar, yet the import of the tradition is one and the same. . .  (Against Heresies I.10.2).

He gives here a powerful statement of Christian unity: a unity which we should all strive for once again. One of the most important aspects of the Catholic Church to me is this same unity: how all throughout the world, no matter the language, the liturgy and the doctrine is the same: the same Christ and the same Church and the same Sacraments.

Here Irenaeus argues for the receipt of true knowledge and doctrine (as opposed to heretical doctrine) by means of the succession of bishops:

True knowledge is [that which consists in] the doctrine of the apostles, and the ancient constitution of the Church throughout all the world, and the distinctive manifestation of the body of Christ according to the successions of the bishops, by which they have handed down that Church which exists in every place, and has come even unto us, being guarded and preserved without any forging of Scriptures, by a very complete system of doctrine, and neither receiving addition nor [suffering] curtailment [in the truths which she believes]; and [it consists in] reading [the word of God] without falsification, and a lawful and diligent exposition in harmony with the Scriptures, both without danger and without blasphemy; and [above all, it consists in] the pre-eminent gift of love (2 Corinthians 8:1; 1 Corinthians 13), which is more precious than knowledge, more glorious than prophecy, and which excels all the other gifts [of God] (Against Heresies IV.33.8).

St. Paulinus of Nola

Ah, the weekend. I’m working on a pretty substantial post that I think will be worthwhile — but I don’t think I’m going to finish tonight.

Today is the Feast of St. Paulinus of Nola (354–431), a pagan convert, bishop, and poet, and a contemporary and friend of St. Augustine. Born of a wealthy Roman family of the senatorial class, educated in the richest literary tradition, he rejected his worldly wealth and devoted himself to Christ following the sorrow of the death of his first child. In the poem I excerpt below, he writes to his friend and mentor Ausonius extolling the virtues of Christ and his total commitment to Him, and defending his rejection of the pagan Muses:

St. Paulinus of Nola

St. Paulinus of Nola.

Why, father, do you bid the deposed Muses return to my charge? Hearts dedicated to Christ reject the Latin Muses and exclude Apollo. Of old you and I shared common cause . . . in summoning deaf Apollo from his cave at Delphi, invoking the Muses as deities, seeking from groves or mountain ridges that gift of utterance bestowed by divine gift. But now another power, a greater God, inspires my mind and demands another way of life. He asks back from man His own gift, so that we may live for the Father of life. He bids us not spend our days on the emptiness of leisure and business, or on the fictions of literature, so that we may obey His laws and behold His light which is clouded by the clever powers of philosophers, the skill of rhetoricians, and the inventions of poets. These men steep our hearts in what is false and empty. They form only men’s tongues, and bring nothing to bestow salvation or to clothe us in the truth. What good, what truth can they possess who do not have the Head of all, God who is the Kindling and the Source of truth and goodness, whom no man sees except in Christ?

He is the Light of truth, the Path of life, the Power and Mind, Hand and Strength of the Father. He is the Sun of justice, Source of blessings, Flower of God, God’s Son, Creator of the world, Life of our mortality, and Death to our death. He is the Master of the virtues. He is God to us and became Man for us by stripping off His nature and assuming ours, forging eternal relations between man and God, while He Himself is both. So when He has flashed His rays over our hearts, He cleans the enfeebling foulness from our sluggish bodies and renews the dispositions of our minds. All that delighted us before He draws away, and in its stead leaves a pleasure that is chaste. By His rights as Lord He demands wholly our hearts, tongues, and heads. He wishes to be the object of our thought and understanding, our belief and reading, our fear and love. . . .

St. Barnabas

St. Barnabas

St. Barnabas

Today is a slow day. It’s the Feast of St. Barnabas, with whom Protestants ought to be familiar as an important figure of the New Testament Church and faithful companion of the Apostle Paul. There is a much more vivid tradition about Barnabas in the Eastern Orthodox Church than here in the West, of which I was fascinated to read. Barnabas is celebrated as the founder of the Church of Cyprus, an apostle*, and a martyr.

* We in the West tend to associate the term “Apostle” with the Twelve — those disciples who were specially chosen by Christ as His closest companions and ministers, who were with Christ and witnessed his life, miracles, and Resurrection — and to Paul, to whom Christ appeared “as to one untimely born” (1 Cor 15:8). In the East they seem to use it more loosely and literally: Greek ἀπόστολος (apóstolos) is someone who was sent.

What is a Saint? An Introduction for Protestants

All Saints

Fra Angelico. The Forerunners of Christ with Saints and Martyrs (about 1423-24).

It occurred to me the other morning in the shower (that’s where thoughts usually occur to me) that many Protestants might be troubled by the concept of saints and sainthood. I have heard Protestants say, “We don’t believe in saints.” I assure you that you do. Do you believe that there are people in Heaven? Then you believe in saints.

Martyrdom of Ignatius

The Martyrdom of St. Ignatius of Antioch.

A saint, very simply — in the sense that the Roman Catholic Church declares one a saint and grants “Saint” as a title — is someone whom we believe, with certainty, is in Heaven. That’s all. From Latin sanctus (Greek ἁγιος or hagios), the word means “holy, sacred, set apart.” In biblical usage, as Protestants should be aware, “saints” refers to all the “holy ones,” the believers of the Church. When we state in the Apostles’ Creed that we believe in the “communion of saints,” we are saying that we believe all believers, both those who are living and those who have died, are a part of our Body and share in our communion with Christ. The author of the Epistle to the Hebrews envisions in the Old Testament saints and prophets a “great cloud of witnesses” surrounding us (playing on μαρτυρέω, testify, bear witness, in Heb 11:39, and μάρτυρες, witnesses [also the same word as martyrs], in Heb 12:1), evoking the image of spectators in an arena as we “run . . . the race that is set before us.” How much more would those who die in Christ join this “cloud”!

Catholics venerate saints — we respect, honor, and revere them; we celebrate their memory — because of their great witness and example for us in faith, virtue, and godliness. They are the heroes of the faith whose godly lives we want to remember and whom we want to emulate. They are our spiritual ancestors, our predecessors, our loved ones, the members of our family who have gone to their reward, and yet are still with us in communion with Christ. We do not worship the saints; only God is worthy of worship. We venerate them in much the same way Americans venerate the memory of George Washington or Abraham Lincoln.

Friends and Family

We have an unlimited calling plan.

So why do Catholics pray to saints? Well, if we believe that they too are part of our communion in Christ, a “great cloud of witnesses,” then why should we be separated from them? They are our friends and family, our brothers and sisters in the Lord who have crossed the river before us. They are already by Christ’s side. Why shouldn’t they pray for us? And aren’t they in a better position for that, to bring our needs and requests before God? Catholics believe that the saints can intercede for us. Praying to saints is nothing more than asking our loved ones to pray for us.

St. Luke the Evangelist

St. Luke the Evangelist, patron saint of physicians. (Simone Martini)

So what is the deal with patron saints? Well, just as the saints had particular interests and causes and affinities when they were here on earth, they do in Heaven too. A saint is held to be the patron (Latin patronus, protector, defender, advocate, patron — yes, like in Harry Potter) of the profession, activity, nation, cause, or place with which they were associated in earthly life. He or she is held to be a patron against specific diseases, afflictions, and dangers when, through suffering or death, they have gained victory over those things in Christ. And, through tradition, through practice, through trial and error, saints are held to be the patrons of these things because their intercession proves efficacious: because prayers for their aid in those causes work. Saints don’t have magical powers. Saints don’t, in themselves, produce effects on this earth. But by where they are and whom they’re with, they have immense spiritual power to intercede on our behalf.

St. Isidore of Seville

St. Isidore of Seville, paron saint of the Internet. (Bartolomé Esteban Murillo, 1655).

So what about relics? Why the macabre obsession with dead body parts? You may or may not be aware that in every Catholic altar there is a relic of some saint (Latin relictum, that which is left behind or remaining) — usually a small piece of bone or some other body part, but sometimes the whole body, or possibly an object the saint owned or touched. We hold that the person, his or her spirit, is in Heaven with Christ — but that the things which the saint left behind, his physical body most of all, offers a connection, an anchor, a bridge to their presence in that spiritual realm. The idea of placing relics under our altars — or building our churches and altars over their remains, as in the cases of Saint Peter and Saint Paul and many other ancient saints — is that by proximity to these connections, by association with these saints, we can draw as near to Heaven and to God as possible.

One last thing: Aren’t all Christians who die saints? We do believe that all Christians who die in the grace of God will go to Heaven, yes; but we also believe in Purgatory — which is a another kettle of fish that will require another post or three. But briefly: It is the calling of every Christian to take part in the life of Christ’s grace, to live within His Church and Sacraments, to pursue holiness and grace and daily be sanctified and converted (Latin converto, turn towards, change, transform) to Christ’s image. Most of us are not able to be fully transformed in this life — so for us there is a time of Purgatory, a fire in which we will be purified of our faults and made ready to stand before God. (No, we’re not being punished for our sins — Christ has already paid the penalty for those, the death we deserve — but spiritually, we still need to be purified. But — another time.)

St. Thérèse

St. Thérèse of Lisieux, the Little Flower of Jesus.

Saints, on the other hand, are very special people who, through life in God’s grace, did achieve holiness and become wholly molded to Christ’s image in this life, to the extent that they could as fallen creatures. (Cf. the Wesleyan idea of entire sanctification.) They are people whose godliness is not in doubt, people like the Apostles and St. Francis and St. Thérèse. These days, there are so many very godly people dying that there is a formal process of canonizaton in the Church, through which a person’s sainthood is confirmed and verified, as best as we on Earth can: by asking them for intercession and seeing if those prayers are answered. Two or three miracles associated with a saint’s intercession is the usual standard. A martyr’s death is the saint’s golden ticket to immediate canonization: they pay the price in blood.

Are there Protestant saints? You bet. Just because someone hasn’t been formally declared a saint by the Church doesn’t mean they’re not one. Walk through any cemetery, and there are likely to be unknown saints lying all around, people who led truly godly lives and who merited Christ’s reward as soon as they crossed over from this life. Catholics are never in the business of declaring who isn’t or who can’t be saved, or who isn’t or can’t be saints: we believe God, in his infinite mercy, grants His grace and His favor according to His own will.

St. Ignatius of Antioch on the Episcopacy

Ignatius of Antioch

St. Ignatius of Antioch

St. Ignatius, Bishop of Antioch, is one of our most vivid testimonies to the Early Church at the beginning of the second century. Arrested by the Roman Empire and sentenced to die, ca. A.D. 108, Ignatius wrote a series of letters to various churches while en route to his martyrdom in the arena at Rome. In his Epistle to the Smyrnaeans, he gave the Church at Smyrna a particularly strong admonition regarding adherence to their bishop. To us it attests to the early offices and roles of the bishop and priests as ministers of the Sacraments.

“See that you all follow the bishop, even as Jesus Christ does the Father, and the presbytery [priesthood] as you would the apostles; and reverence the deacons, as being the institution of God. Let no man do anything connected with the Church without the bishop. Let that be deemed a proper Eucharist, which is [administered] either by the bishop, or by one to whom he has entrusted it. Wherever the bishop shall appear, there let the multitude [of the people] also be; even as, wherever Jesus Christ is, there is the Catholic [Universal] Church. It is not lawful without the bishop either to baptize or to celebrate a love-feast; but whatsoever he shall approve of, that is also pleasing to God, so that everything that is done may be secure and valid.”

Epistle to the Smyrnaeans 8

St. Boniface, Apostle of the Germans

St. Boniface

St. Boniface

Today is the Feast of St. Boniface (c. 7th century – 754), known as the Apostle of the Germans. Born with the name Wynfrith in the English kindgom of Wessex, he was renamed Boniface by Pope Gregory II, who commissioned him. He spent the last thirty years of his life as a missionary to the Germanic peoples, especially in the region of Frisia. He was the first archbishop of Mainz, and died a martyr for the faith while on a mission to convert the Frisians. St. Boniface leaves behind a sizable body of correspondence, his letters to and responses from popes, bishops, abbots, and nuns: his superiors, associates, and friends. I’ve selected a particularly touching passage from a letter of Boniface to his dear friend
Bishop Daniel of Winchester:

News was brought to me recently by a priest who came to Germany from your parts that you had lost your sight. You, my lord, are more aware than I am who it is who said: “Where he loves, he bestows correction.” And St. Paul says: “When I am weakest, then I am strongest of all”; and: “My strength is increased in infirmity.” The author of the psalms adds: “Many are the trials of the innocent,” etc. You, my father, have eyes like those of Didimus, of whom Antony is related to have said that his eyes saw God and His angels and the blessed joys of the heavenly Jerusalem. On this account, and because I know your wisdom and your patience, I believe that God has permitted you to be afflicted in this way so that your virtue and merit may increase and that you may gaze with the eyes of the spirit on those things which God loves and commands, whilst seeing less of the things God hates and forbids. What are our bodily eyes in this time of trial but the windows of sin through which we observe sins and sinners, or, worse still, behold and desire them and so fall into sin?

St. Justin Martyr on Christian Baptism

St. Justin Martyr (100–165) was a second-century Christian apologist and one of our earliest testimonies to the worship of the Early Church. A pagan convert, he died a Christian martyr in Rome. In St. Justin’s First Apology (ca. 150), he writes regarding Christian Baptism:

Justin Martyr

St. Justin Martyr (André Thevet, Les Vrais Pourtraits et Vies Hommes Illustres, 1584) (Wikipedia)

I will also relate the manner in which we dedicated ourselves to God when we had been made new through Christ; lest, if we omit this, we seem to be unfair in the explanation we are making. As many as are persuaded and believe that what we teach and say is true, and undertake to be able to live accordingly, are instructed to pray and to entreat God with fasting, for the remission of their sins that are past, we praying and fasting with them. Then they are brought by us where there is water, and are regenerated in the same manner in which we were ourselves regenerated. For, in the name of God, the Father and Lord of the universe, and of our Saviour Jesus Christ, and of the Holy Spirit, they then receive the washing with water. For Christ also said, “Unless you be born again, you shall not enter into the kingdom of heaven” (John 3:5). Now, that it is impossible for those who have once been born to enter into their mothers’ wombs, is manifest to all. And how those who have sinned and repent shall escape their sins, is declared by Esaias [Isaiah] the prophet, as I wrote above; he thus speaks: “Wash you, make you clean; put away the evil of your doings from your souls; learn to do well; judge the fatherless, and plead for the widow: and come and let us reason together, says the Lord. And though your sins be as scarlet, I will make them white like wool; and though they be as crimson, I will make them white as snow. But if you refuse and rebel, the sword shall devour you: for the mouth of the Lord has spoken it” (Isaiah 1:16-20).

And for this [rite] we have learned from the apostles this reason. Since at our birth we were born without our own knowledge or choice, by our parents coming together, and were brought up in bad habits and wicked training; in order that we may not remain the children of necessity and of ignorance, but may become the children of choice and knowledge, and may obtain in the water the remission of sins formerly committed, there is pronounced over him who chooses to be born again, and has repented of his sins, the name of God the Father and Lord of the universe; he who leads to the laver the person that is to be washed calling him by this name alone. For no one can utter the name of the ineffable God; and if any one dare to say that there is a name, he raves with a hopeless madness. And this washing is called illumination, because they who learn these things are illuminated in their understandings. And in the name of Jesus Christ, who was crucified under Pontius Pilate, and in the name of the Holy Ghost, who through the prophets foretold all things about Jesus, he who is illuminated is washed.

Early Testimonies to St. Peter’s Ministry in Rome

St. Peter

Peter Paul Rubens. St. Peter. c. 1611. Oil on canvas.

So I’m realizing why the “tomb of st. peter” is such a popular search term. It seems the issue of St. Peter’s presence and ministry in Rome is one of the major points of contention between Catholics and many Protestants (especially those of an anti-Catholic bent). This is somewhat surprising to me. Even as a Protestant, there was never any question in my mind that Peter ministered and died in Rome — perhaps because I’m also an historian. The historical evidence for Peter being in Rome is not just solid; it’s unanimous. Every historical record that speaks to Peter’s later life and death attests that he died in Rome a martyr under the emperor Nero, ca. A.D. 67. No record places the end of his life anywhere else.

The fact that so many people are searching on Peter in Rome tells me that people are hearing conflicting statements and wondering, searching for the truth. The fact that so many Protestants deny it so vehemently, and refute it so absurdly, tells me that they, however basically, realize the power in our claim. They recognize and in effect acknowledge what we have maintained for many centuries: that having the chief of Apostles as our foundation gives the Roman Catholic Church legitimacy and primacy.

Why else would it be so important to refute that St. Peter was here? He was but a man who died nearly 2,000 years ago. If, as Protestants charge, the Catholic Church left its apostolic foundations long ago and drifted over the centuries into corruption, why should it be so significant what those foundations were? Why deny a well-attested historical fact unless it carries some continuing authority? Do they not realize that in attacking the Roman Church’s foundations, they are undermining their own — since we are their Mother Church, too?

The primary reason for this opposition, I suspect, is that in a fundamentalist view, all religious truth must come from Scripture, sola scriptura — and it is not self-evident from Scripture that St. Peter was ever in Rome. This is also the reason why few Protestants seem to dispute that St. Paul was in Rome: because he tells us he was, repeatedly, in his scriptural epistles. Most more thoughtful Protestants realize that there is a difference between religious truth and historical truth, however intertwined the two may sometimes be; and historical sources are valid authorities for historical truth. These tend to be, incidentally, the Protestants least inclined toward anti-Catholicism.

First Epistle of St. Peter

But the Bible can be an historical source, too. And there is actually a significant testimony in the Bible to Peter’s presence in Rome. In the valediction of Peter’s first epistle, he wrote (1 Peter 5:13 ESV):

She who is at Babylon, who is likewise chosen, sends you greetings, and so does Mark, my son.

Here the Greek grammar is clear: ἀσπάζεται ὑμᾶς (sends greetings to y’all) ἡ ἐν βαβυλῶνι (she who is in/at Babylon) συνεκλεκτὴ (she elected/chosen together) καὶ Μᾶρκος (and also Mark) ὁ υἱός μου (my son). Peter, writing the letter, and therefore sending the greetings, is obviously with “she who is at Babylon,” and also with Mark, “[his] son.” She elected is the Church, always personified as a woman; and Peter is with the Church. But the Church where? The ancient city of Babylon had been in ruins for centuries. Peter must have been speaking in a cryptic metaphor. The Babylon of the Bible was the capital of a vast, powerful empire, and stood at the height of sin and excess. Where else could that be in Peter’s day but Rome?

You don’t have to take my word for it. From the study notes of the well-respected, evangelical ESV Study Bible (which continues to be my personal Bible of choice):

1 Pet. 5:13 She who is at Babylon, who is … chosen almost certainly refers to the church in Rome, not a literal woman (cf. “elect lady,” 2 John 1, 13). Although the Babylon of the OT was in ruins, the reference resonates with the OT, where “Babylon” represents a center of earthly power opposed to God (cf. Isaiah 13–14; Jeremiah 50–51; see also Revelation 17–18), and in Peter’s day that city would be Rome. The language of “Babylon” and “chosen” forms an inclusio (a literary envelope) with the first verse of the book: the OT background to “Babylon” reminds believers that though they are exiles, they are “elect exiles” (1 Pet. 1:1) who will receive the promised inheritance. Mark is the same John Mark who traveled with Paul and Barnabas on their first missionary journey (cf. Acts 12:25; 13:5, 13; 15:36–39). Though he left Paul and Barnabas, he was later restored to his former usefulness (Col. 4:10; 2 Tim. 4:11; Philem. 24). Peter would have known Mark from the earliest days, because the church met in his mother’s home (Acts 12:12). In addition, this verse shows a close relationship between Peter and Mark (my son) and is one indication of the validity of the early church tradition that Mark wrote his Gospel at Peter’s direction.

Writing under the emperor Nero, Peter would wisely have used discretion in revealing his whereabouts in writing, lest his letter be intercepted by Roman authorities. The symbolism that is transparent to Christians today would not have been so explicit to those not so steeped in the Old Testament or ancient Mesopotamian history.

St. Clement of Rome

Among the earliest surviving testimony outside the Bible is the first letter of Clement (1 Clement), which is usually dated to around 95 or 96 A.D. Clement of Rome, as evident from the letter, was a high official of the Church in Rome, writing in exhortation to the Church at Corinth to settle a division between the established elders and an upstart faction. The Roman Catholic Church today holds St. Clement to have been the third bishop of Rome (i.e. pope); early patristic writers varied in their listings, placing Clement anywhere from second to fourth. His letter is a clear early example of the bishop of Rome exerting authority over other churches.

Regarding St. Peter, St. Clement did not speak to the specifics of Peter’s fate, but wrote (1 Clement 5–6, trans. Kirsopp Lake, in The Apostolic Fathers, vol. I, Loeb Classical Library, London and New York: William Heinemann, 1919):

But, to cease from the examples of old time, let us come to those who contended in the days nearest to us; let us take the noble examples of our own generation. Through jealousy and envy the greatest and most righteous pillars of the Church were persecuted and contended unto death. Let us set before our eyes the good apostles: Peter, who because of unrighteous jealousy suffered not one or two but many trials, and having thus given his testimony (μαρτυρήσας) went to the glorious place which was his due. Through jealousy and strife Paul showed the way to the prize of endurance; seven times he was in bonds, he was exiled, he was stoned, he was a herald both in the East and in the West, he gained the noble fame of his faith, he taught righteousness to all the world, and when he had reached the limits of the West he gave his testimony (μαρτυρήσας) before the rulers, and thus passed from the world and was taken up into the Holy Place,―the greatest example of endurance. To these men with their holy lives was gathered a great multitude of the chosen, who were the victims of jealousy and offered among us (ἐν ἡμῖν) the fairest example in their endurance under many indignities and tortures.

Clement was the first writer to place Saints Peter and Paul as a pair, as they have always been in the Roman Church. He showed a clear and personal knowledge of the deaths of both Peter and Paul, and he assumed that his recipients also knew the stories. Most Christians accept that Paul was martyred in Rome; it is not a far stretch to assume from Clement’s pairing of the two Apostles that he also believed Peter to have died in Rome. In fact, his grammar is revealing: Peter and Paul offered their example—their martyrdom—“among us” (ἐν ἡμῖν)—that is, among the Romans. Clement was consistent throughout his letter in the use of the pronouns ὑμεῖς (you, i.e. Corinthians) and ἡμεῖς (we, us, i.e. Romans).

St. Ignatius of Antioch

St. Ignatius of Antioch, in his Epistle to the Romans, dated between 98 and 117, written en route to his martyrdom at Rome, referenced the Saints Peter and Paul (Epistle to the Romans IV):

I do not enjoin you in the manner of Peter and Paul. They were Apostles; I am a condemned man. They were free; I, until this moment, am a slave.

Again he placed Peter and Paul as a pair, and implied that the Romans have had personal contact with the Apostles, who enjoined them with authority.

St. Irenaeus of Lugdunum (Lyon)

St. Irenaeus, writing ca. 180, is the earliest extant writer I’ve found that stated directly that Peter ministered in Rome (Against Heresies III.1.1):

For, after our Lord rose from the dead, [the apostles] were invested with power from on high when the Holy Spirit came down [upon them], were filled from all [His gifts], and had perfect knowledge: they departed to the ends of the earth, preaching the glad tidings of the good things [sent] from God to us, and proclaiming the peace of heaven to men, who indeed do all equally and individually possess the Gospel of God. Matthew also issued a written Gospel among the Hebrews in their own dialect, while Peter and Paul were preaching at Rome, and laying the foundations of the Church. After their departure, Mark, the disciple and interpreter of Peter, did also hand down to us in writing what had been preached by Peter.

And again (Against Heresies, III.3.1-2):

It is within the power of all, therefore, in every Church, who may wish to see the truth, to contemplate clearly the tradition of the apostles manifested throughout the whole world; and we are in a position to reckon up those who were by the apostles instituted bishops in the Churches, and [to demonstrate] the succession of these men to our own times; . . . [We refute the heretics] by indicating that tradition derived from the apostles, of the very great, the very ancient, and universally known Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also [by pointing out] the faith preached to men, which comes down to our time by means of the successions of the bishops. For it is a matter of necessity that every Church should agree with this Church, on account of its preeminent authority, that is, the faithful everywhere, inasmuch as the tradition has been preserved continuously by those [faithful men] who exist everywhere.

Here we have, clearly stated, not only the statement that Saints Peter and Paul built the Church at Rome—not that they were the first Christian missionaries there, but that by their apostolic ministry they laid its foundations—but also, Irenaeus affirmed the doctrines of Apostolic succession and Petrine primacy, unequivocally and authoritatively, at a date earlier than many Protestants would like to recognize. What is more, St. Irenaeus was not a partisan of the Church at Rome, but the Greek-born bishop of Lugdunum (today the city of Lyon in France). In the face of the growing threat of Gnosticism, the unity of the Church and the authority of Rome were more important than ever.

Clement of Alexandria

Clement of Alexandria, who wrote between ca. 190 and 215, made several references to Peter’s ministry in Rome, especially as it pertained to the ministry of St. Mark, founder of the Church at Alexandria. Some of these references survive only in fragments. The first, from Clement’s Commentary on the First Epistle of Peter, which survives only in the Latin translation of Cassiodorus:

Mark, the follower of Peter, while Peter publicly preached the Gospel at Rome before some of Caesar’s equites, and adduced many testimonies to Christ, in order that thereby they might be able to commit to memory what was spoken, of what was spoken by Peter, wrote entirely what is called the Gospel according to Mark.

The Church historian Eusebius of Caesarea, writing in the 290s, cited Clement’s lost Hypotyposes, as well as the testimony of Papias of Hierapolis, also otherwise lost, further attesting that Mark wrote his Gospel from the teachings of Peter at Rome (Church History II.15.2).

Tertullian

Tertullian, writing probably ca. 180-200, attested to Peter’s and Paul’s ministry and martyrdom in Rome in a passage from De praescriptionem haereticorum (Prescription against Heretics 36). Like Irenaeus, he appealed to the apostolic foundations of the orthodox churches:

Come now, you who would indulge a better curiosity, if you would apply it to the business of your salvation, run over the Apostolic churches, in which the very thrones of the Apostles are still pre-eminent in their places, in which their own authentic writings are read, uttering the voice and representing the face of each of them severally. . . . Since, moreover, you are close upon Italy, you have Rome, from which there comes even into our own hands the very authority [of Apostles themselves]. How happy is its church, on which Apostles poured forth all their doctrine along with their blood! Where Peter endures a passion like his Lord’s! Where Paul wins his crown in a death like John’s where the Apostle John was first plunged, unhurt, into boiling oil, and thence remitted to his island-exile!

Eusebius of Caesarea

Eusebius, compiling his Church History in the 290s, firmly stated the well-established tradition of Peter’s martyrdom in Rome (Church History II.25.5):

Thus publicly announcing himself as the first among God’s chief enemies, [Nero] was led on to the slaughter of the apostles. It is, therefore, recorded that Paul was beheaded in Rome itself, and that Peter likewise was crucified under Nero. This account of Peter and Paul is substantiated by the fact that their names are preserved in the cemeteries of that place even to the present day.

Eusebius cited as testimony earlier writers, and thus preserved a number of valuable fragments of works no longer extant. Among them is the previously discussed quotation which attests to the presence of Peter’s grave monument on Vatican Hill in ca. 210 (II.25.6–7):

It is confirmed likewise by Gaius, a member of the Church, who arose under Zephyrinus, bishop of Rome. He, in a published disputation with Proclus, the leader of the Phrygian heresy, speaks as follows concerning the places where the sacred corpses of the aforesaid apostles are laid: ‘But I can show the trophies of the Apostles. For if you will go to the Vatican or to the Ostian way, you will find the trophies of those who laid the foundations of this church.’

Finally, Eusebius preserved a document from Dionysius of Corinth, Bishop of Corinth in 171, attesting that both Peter and Paul had ministered in Corinth before going to Rome, and that they had died in Rome at the same time (i.e. under the same persecution) (II.25.8):

And that they both suffered martyrdom at the same time is stated by Dionysius, bishop of Corinth, in his epistle to the Romans, in the following words: ‘You have thus by such an admonition bound together the planting of Peter and of Paul at Rome and Corinth. For both of them planted and likewise taught us in our Corinth. And they taught together in like manner in Italy, and suffered martyrdom at the same time.’ I have quoted these things in order that the truth of the history might be still more confirmed.

This carries the documentary record of the ministry and martyrdom of St. Peter in Rome to the end of the third century. His presence there is suggested even by the Apostle himself in 1 Peter. His martyrdom there is attested to arguably as early as 95 or 96 by St. Clement, within thirty years of Peter’s death. It certainly is strongly attested by St. Irenaeus in ca. 180, after only little more than a century. Voices from all around the Mediterranean world affirm Peter’s residence in Rome, as well as Rome’s primacy.

No other writer or record places the end of Peter’s life anywhere but Rome. The majority of the earliest testimonies to the Early Church attest to it, and for nearly 1500 years, Peter’s apostolic ministry in Rome was universally accepted and unquestioned throughout the Church. As the Catholic Encyclopedia announced confidently, “St. Peter’s residence and death in Rome are established beyond contention as historical facts.”
