Justified True Belief

(●) Against a Christianity of secret knowledge he pointed at three things every congregation already had: four Gospels, a short shared summary of the faith, and a public list of teachers. + Imagine a man in a river town on the edge of the empire, a long way from anywhere that mattered, sitting down with a stack of books he had gone to some trouble to obtain. They were the books of his opponents, and they were beautiful: elaborate accounts of thirty divine beings, of a lower god who had botched the making of the world, of a secret knowledge handed down from the apostles to a chosen few, and of a Christ who had only seemed to have a body. The men who wrote them were charming and well read, and they were not outside the churches shouting in. They were inside, teaching, and their pupils sat in the same rooms as everybody else. That is what made these books the cleverest heresy of the second century, a heresy being not merely an opinion somebody dislikes but a teaching the churches had weighed against what they had received and judged to be a different religion wearing Christian words. It is also why the bishop of Lyons spent years reading them. His answer, when it came, was not a cleverer system. It was a set of things anyone could check. There are four Gospels and they were public property from the beginning. There is a short summary of the faith that the churches in Gaul and Egypt and the East all say in nearly the same words. And there are names: you can walk into any old church and list the men who taught there, one after another, back to an apostle. Nothing hidden, nothing for insiders only. If the truth had been handed down in a whisper, he asked, why can nobody produce the whisperers? Irenaeus is on a Christian apologetics site for a reason that has nothing to do with nostalgia. The three moves he made are still the shape of the Christian answer to a claim of lost or suppressed gospels, and the historical questions he was pressing (which Gospels, whose testimony, how early) are still the ones the argument turns on. He also carries one fact worth remembering. He is the last Christian writer we know of who could say, and mean it literally, that he had watched a man who had listened to the apostle John.

(●) c. 130 AD: Born somewhere in Asia Minor, probably near Smyrna, where as a boy he sat in the crowd around Polycarp, an old bishop who had known the apostle John. + Nobody wrote down the year Irenaeus was born, and the estimates run from about 130 to about 140 AD. Nobody recorded his birthplace either. What he tells us himself is that as a boy he heard Polycarp, the bishop of Smyrna on the Aegean coast, and since a boy does not commute to hear a bishop, historians place his childhood in Smyrna or somewhere near it. He grew up speaking Greek, and Greek is the language he wrote in for the rest of his life. Around the year 190, decades later and most of a continent away, he sat down to write to an old acquaintance named Florinus, who had drifted into a heresy. It is a letter about that, and it turns out to be the best evidence we have about his own childhood, because what he does first is remind Florinus of the room they both remember. He can still see it. "I remember the events of that time more clearly than those of recent years," he wrote. "For what boys learn, growing with their mind, becomes joined with it; so that I am able to describe the very place in which the blessed Polycarp sat as he discoursed, and his goings out and his comings in, and the manner of his life, and his physical appearance, and his discourses to the people, and the accounts which he gave of his intercourse with John and with the others who had seen the Lord." (Eusebius, Church History V.20.6, McGiffert translation.) Read that chain slowly, because it is short and it is the reason his testimony carries weight. Jesus taught John. John taught Polycarp. Polycarp taught a boy who lived long enough to write five books. Irenaeus was not repeating a rumour about the apostles; he had watched a man remember them out loud.

(●) 177 AD: While he carried a letter to Rome, a mob and a governor were destroying the church at Lyons that had sent him. + By the 170s Irenaeus was a presbyter (an elder, one of the senior teaching clergy) at Lugdunum, the Roman city on the Rhône that is now Lyons in France. It was a merchant town full of traders from the eastern Mediterranean, which is probably how a Greek from Asia Minor came to be there at all. Whatever brought him, he was a long way from Smyrna and the Aegean. Then, in the summer of 177, the city turned on its Christians. The surviving congregations of Lyons and the neighbouring town of Vienne wrote an account of what happened, and Eusebius copied it out nearly a century and a half later. It is one of the most harrowing documents of the ancient church, and what stays with a reader is how ordinary the machinery of it was: slaves tortured until they would accuse their masters, a young woman named Blandina who outlasted her executioners, and the bishop Pothinus, over ninety years old and barely able to breathe, dragged to the judgment seat and thrown into prison, where he died after two days. Irenaeus was not there for the worst of it. The confessors, which is what the churches called the Christians still alive in prison awaiting sentence, had chosen him to carry a letter over the Alps to Eleutherus, the bishop of Rome, about a controversy then dividing the churches of Asia Minor. Their note of introduction survives, and it is a good measure of the man they were sending: "We have requested our brother and comrade Irenæus to carry this letter to you, and we ask you to hold him in esteem, as zealous for the covenant of Christ." (Eusebius, Church History V.4.2, McGiffert translation.) They wrote it from a cell, and most of them did not live to see him come back.

(●) c. 178 AD: He came home to a church that had lost its bishop and much of its congregation, and the survivors made him the next bishop. + He came back over the Alps to find Pothinus dead and the congregation gutted, and the people who were left asked him to take the empty chair. Almost nothing is recorded of the twenty-odd years that followed except the books, and that silence is itself worth noticing. A man who had every reason to write bitterly about Rome, the empire that had just killed his friends, wrote instead about how the churches agree. One line does let us hear the daily texture of the job. Apologizing at the start of his great work for the plainness of his Greek, he tells his reader, "Thou wilt not expect from me, who am resident among the Keltæ, and am accustomed for the most part to use a barbarous dialect, any display of rhetoric" (Against Heresies I, Preface 3, Roberts and Rambaut translation). The Keltae are the Gauls, and the barbarous dialect is Celtic. Here is a bishop who had learned the local language well enough to preach in it, and who had lost some of his Greek polish in the bargain, and who then made a virtue of the loss. Somewhere among those Gaulish villages, he says, are nations who believe "having salvation written in their hearts by the Spirit, without paper or ink" (Against Heresies III.4.2). He knew people who could not read a Gospel and held the faith anyway, and it shaped how he would argue.

(●) c. 180 AD: He read the Gnostics’ own books and answered them in five books of his own, the work everyone now calls Against Heresies. + His own title for them was On the Detection and Overthrow of the Knowledge Falsely So Called, a phrase he borrowed from 1 Timothy 6:20. Everyone since has called it Against Heresies. It can be dated to roughly 180 AD because in the third book he names Eleutherus as the bishop currently at Rome (III.3.3), and Eleutherus died around 189. The target was Gnosticism, and the word needs unpacking, because it names a family of movements rather than a church. Gnosis is simply the Greek for knowledge, and what the Gnostic teachers offered was a saving knowledge: the discovery that the spark inside you does not belong to this world, that the god who made this world is a lesser and blundering being, and that the material creation is therefore a mistake to escape rather than a gift to receive. On that account your body is not a good thing gone wrong. It is the trap. The most sophisticated version of all this in Irenaeus’s day belonged to the school of Valentinus, a teacher who had worked at Rome a generation earlier, and whose followers stayed inside ordinary congregations, singing the ordinary hymns, while reading Scripture as an elaborate code that said something else. What Irenaeus did first was unglamorous and decisive. He got hold of their writings and the reports of people who had left them, and then he set the systems out at length in his first book, in their own vocabulary, before he answered a word of it. He compared what they were doing to a portrait made of gems. A skilful artist sets precious stones into the likeness of a king; someone else then takes the picture to pieces, refits the same stones into the shape of a dog or a fox, and assures newcomers that this was the original all along (Against Heresies I.8.1). Every stone is genuine. The picture is a lie. Scripture, he thought, was being handled exactly that way, and the way to stop it was not to argue about individual stones but to show the reader the king.

(●) c. 190 AD: He talked the bishop of Rome out of cutting off the churches of Asia over the date of Easter. + The quarrel looks small, and it was not. The churches of Asia Minor kept the yearly commemoration of the Lord’s death on the fourteenth day of the Jewish month Nisan, whatever day of the week that happened to be, and they said they had the practice from the apostle John. Most of the rest of the church waited and kept the resurrection on the following Sunday. In the same week, then, one congregation could still be fasting while another, a few days’ journey away, had already broken its fast and was keeping the feast. Victor, bishop of Rome, decided the Asian practice had to stop, and moved to declare those churches out of communion, which is to say cut off from fellowship with the rest, the step later generations would call excommunication. Irenaeus agreed with Victor about Sunday, and said so. Then he told him he was wrong to break the churches over it. His letter, which Eusebius quotes, is an appeal to history: the difference is older than the men now arguing about it, earlier bishops of Rome had tolerated it, and "none were ever cast out on account of this form" (Church History V.24.15, McGiffert translation). Those predecessors, he pointed out, had gone on sending the eucharistic bread, the bread of the Lord’s Supper, to congregations that kept the other date, which is a picture worth holding on to. The disagreement was real and the loaf still went out. Eusebius could not resist the pun and neither should anyone else, since the name means peaceful: "Thus Irenæus, who truly was well named, became a peacemaker in this matter, exhorting and negotiating in this way in behalf of the peace of the churches." (Church History V.24.18, McGiffert translation.) The threatened excommunication did not happen.

(●) c. 202 AD: He died at about seventy, and nobody tells the story of his martyrdom until four centuries afterwards. + Of his last years nothing is known. The usual date of death, around 202 or 203, comes from linking him to a persecution under the emperor Septimius Severus, and it is a reasonable guess rather than a record. The martyrdom needs a word of its own, because the calendars and the older reference books state it flatly, and the evidence for it is thinner than that. Eusebius admired Irenaeus, collected his letters, and never in his life missed a chance to record a martyr. He does not say Irenaeus was one. Jerome, writing some two hundred years after the fact, calls him bishop and martyr once in passing, in his commentary on Isaiah, and yet says nothing about a martyrdom in the notice he devotes to Irenaeus’s life and works, which is an odd place to leave it out. The first actual account of a death for the faith comes from Gregory of Tours in the late sixth century, four centuries downstream. That is late enough that a careful reader should hold the martyrdom as a tradition of the Gallic church rather than as something we know. What is not in doubt is the shape of the life. A boy in Smyrna who listened to an old man talk about John; an errand to Rome that saved him from a massacre; twenty years as bishop of a wrecked congregation in a town where he preached in a language he had to learn; five books that gave the church its answer to the question of who gets to say what Christianity is.

What He Taught

(T1) Christ did not start the human race over; he went back along it and got it right. + Think about how you fix a piece of music you have been playing wrong. You do not throw the instrument away and buy a new one, and you do not start at the point of the mistake either. You go back to the top and play the whole passage again, correctly, so that the wrong version is not merely stopped but replaced. That is close to what Irenaeus meant by his central idea, and it is worth learning the word for it because everything else in him hangs off it. Recapitulation is the Latin that carries his Greek word, anakephalaiosis, which means going back over something and gathering it under one head. Irenaeus took it from Paul, who uses that very verb for God’s plan to unite, to sum up, all things in Christ (Ephesians 1:10). Applied to salvation it means this: the Son of God became a real human being and lived a human life all the way through, infancy, childhood, youth, adulthood, and death, and at every point where Adam had gone wrong he went right. Adam disobeyed at a tree and Christ obeyed at a tree. Adam was made from untilled earth and Christ was born of a virgin. What was lost in the first man is recovered in the second, and the second is not a replacement model but the same nature, put back. Two things follow from that, and both of them were the whole quarrel with the Gnostics. First, the incarnation, God the Son taking on an actual human body and living an actual human life, has to be genuine flesh all the way down: a Christ who only seemed to have a body has not gone back over anything. Second, the same God stands at both ends of the story, because the one who makes the human race is the one who repairs it. Irenaeus liked to put that repair as an exchange. The Word of God, he writes, is "our Lord Jesus Christ, who did, through His transcendent love, become what we are, that He might bring us to be even what He is Himself" (Against Heresies V, Preface). Paul’s Adam-and-Christ passages are the ground of the whole idea (Romans 5:19; 1 Corinthians 15:22), and Irenaeus is the first Christian writer to build a whole theology out of them.

(Q) "God recapitulated in Himself the ancient formation of man, that He might kill sin, deprive death of its power, and vivify man; and therefore His works are true." + Source: Irenaeus, Against Heresies III.18.7 (Roberts and Rambaut translation). The chapter is arguing against teachers who separated the human Jesus from a divine Christ that descended on him. Irenaeus’s reply is that if the two come apart, nothing has been repaired: the ancient formation of man is Adam, and it takes God in the flesh to go back over it (T1).

(T2) There are four Gospels, and there were never going to be more. + The Gnostic teachers had gospels of their own, and they had another habit besides: they liked to pick one of the four and clip it. Marcion, a generation earlier, had kept a shortened Luke and thrown out the rest. The Valentinians leaned on John. The Ebionites, Jewish Christians who kept the law of Moses, used Matthew alone. Irenaeus noticed the pattern, and it is worth noticing still. Every party that walked out of the churches carried away a smaller Bible than the one it left behind. So he stated the church’s position on the canon, meaning the settled list of books a congregation reads aloud as Scripture, and as far as the surviving evidence goes he is the earliest writer to state it as a fixed number. Matthew, Mark, Luke, John. Four, not three and not five, and no fifth to be produced later out of somebody’s drawer. His reason for the number is famously strange to modern ears. There are four zones of the world and four principal winds, and the four living creatures around God’s throne in Ezekiel and Revelation are four, so the Gospel comes to us in four forms held together by one Spirit. Nobody today finds that persuasive as a proof, and it is a mistake to read it as one. He is not deriving the number from the winds. He already has the four from the churches, and what he is doing with the winds is what a preacher does with a number he has been handed, which is to look for the fittingness in it. The argument that carries the weight is the one underneath. These four were being read aloud on Sunday in Rome and Smyrna and Carthage and Lyons, in places that had no way of coordinating with each other, by congregations that could each say where their copy had come from. He is not the only witness to the number, either. An old Roman list of the books the church read, known as the Muratorian fragment, counts the same four and may be as early as he is, though its opening is damaged and scholars argue about when it was written. A gospel that turns up in a single school in Egypt with a claim of secret transmission is not in that category and never was. When someone today reports that the church suppressed the other gospels at a later council, the historical answer was already in print by 180.

(Q) "It is not possible that the Gospels can be either more or fewer in number than they are." + Source: Irenaeus, Against Heresies III.11.8 (Roberts and Rambaut translation). The sentence opens the passage that goes on: "For, since there are four zones of the world in which we live, and four principal winds, while the Church is scattered throughout all the world, and the pillar and ground of the Church is the Gospel and the spirit of life; it is fitting that she should have four pillars, breathing out immortality on every side, and vivifying men afresh" (T2).

(T3) The faith is a short public summary, and any Christian can hold a teacher up against it. + A new believer in second-century Lyons could not check a teacher by opening a Bible, because there were no bound Bibles and most people could not read one anyway. What that believer had was a short statement learned at baptism and heard every week: one God who made everything, one Christ his Son who took flesh from a virgin, suffered, rose and is coming back, one Spirit who spoke through the prophets. Irenaeus calls it the rule of truth, or the rule of faith. It is not a creed in the later sense of a fixed text agreed by a council, since he gives it three times in his surviving works and never in quite the same words. It is a summary with a fixed shape and loose wording, the way a family tells the same story. The use of it is the point. Hand a beginner the rule, and the elaborate reinterpretations lose their grip, because a system that needs the Creator to be a lesser and blundering god has failed at the first clause and the beginner can hear that it has. This is the gem portrait again, worked from the other side. Someone who has seen the picture of the king assembled properly is not easily persuaded that the stones were always meant to be a dog. The claim he makes about all this is a striking one, and it is a claim about agreement. Churches in Germany, Spain, Gaul, Egypt, Libya and the East, speaking different languages and with no way to call a meeting, are teaching the same short thing. He is not describing a bureaucracy, because there was not one to describe. He is describing what he had seen for himself, in three provinces, with his own feet on the ground, and he is offering it as evidence.

(Q) "She also believes these points 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." + Source: Irenaeus, Against Heresies I.10.2 (Roberts and Rambaut translation). The translators supply "of doctrine" in brackets after "these points". The sentence follows immediately on his summary of the rule of faith, and on the observation that the church, "although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it" (I.10.2). Paul’s "one Lord, one faith, one baptism" stands behind the thought (Ephesians 4:5).

(T4) There is no secret line of teachers running past the churches, and the public one can be named man by man. + Every Gnostic school made the same historical claim, and it is the claim that makes the whole thing work: the apostles taught the crowds one thing and a chosen few something deeper, and we are the heirs of the deeper teaching. It cannot be disproved by argument, since a secret is secret. It can be answered by asking for names. That is exactly what Irenaeus does. If the apostles had a hidden doctrine, he says, they would have entrusted it above all to the men they put in charge of the churches they founded, and those men are not anonymous. He offers to list them, and then he does, running through the bishops of Rome from Linus down to Eleutherus, "in the twelfth place from the apostles," and adding Polycarp at Smyrna, whom he had watched with his own eyes, and the church at Ephesus, founded by Paul and with John among them until the reign of Trajan. That public chain, each teacher handing the faith on to the next in a place with a name, is what the church came to call succession. Not one man on any of those lists ever taught the Gnostic systems. The line the Gnostics claim, by contrast, runs through nobody a congregation can point to. One sentence in this stretch has been argued over for centuries, and fairness requires saying so plainly. Writing of the church at Rome, Irenaeus says that "it is a matter of necessity that every Church should agree with this Church, on account of its pre-eminent authority" (Against Heresies III.3.2). The Greek is lost, the surviving Latin is compressed, and Christians have read the line in two ways ever since. Catholic readers take it as an early statement of the primacy of the Roman see, that is, the standing authority of the bishop of Rome over the other churches. Others take it as a claim about evidence: Rome is the capital, believers from everywhere pass through it, so what Rome teaches is the best-attested sample of what the churches teach everywhere. Both readings are held by serious people, and the sentence is thin ground for settling anything by itself. What is not disputed is the move Irenaeus is making with it, which is to answer a claim of secret succession with a public one.

(Q) "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." + Source: Irenaeus, Against Heresies III.3.1 (Roberts and Rambaut translation). "Within the power of all" is the hinge of the argument. Against a doctrine that by definition only a few can inspect, he sets one that anybody can (T4).

(T5) The flesh is not the problem: God made it, Christ wore it, bread and wine feed it, and it will be raised. + Every strand of Gnostic teaching agreed on one thing. Matter is beneath salvation. The body is a shell, the world is a wreck, and the good news is that the spark inside you gets out. Irenaeus thought this was not a variation on Christianity but its reversal, and he spent his fifth book on it. His answer runs along the whole story rather than through a single proof text. God looked at what he had made and called it very good (Genesis 1:31). The Son took actual flesh, and the test of a true spirit is that it says so (John 1:14; 1 John 4:2). The promise at the end is not escape from the body but resurrection of it. Then he adds the argument that is most his own, and it comes off the Sunday table. Week by week Christians take bread and wine at the Eucharist, a word that is simply the Greek for thanksgiving and names the meal other Christians call communion or the Lord’s Supper. Bread and wine are ordinary things grown out of the ground, and God makes them the vehicle of eternal life to the bodies that eat them. A church that does that every week has already granted that matter can carry God’s gifts, and it cannot then turn round and despise the flesh. Christians have long divided over what exactly happens to that bread, and Irenaeus gets quoted on several sides of the question. He is not writing to settle an argument that would not be framed for centuries yet, and the point he is actually making is the one all sides share: the physical creation is God’s, and it is being redeemed rather than discarded. There is a second thing in his account of the body, quieter and much less quoted. Adam and Eve, he thought, were made young, more like children than finished adults, and they were meant to grow into the likeness of God over time. The fall, the first disobedience in the garden, then looks less like a mutiny and more like a child grasping at what was going to be given anyway.

(Q) "For as the bread, which is produced from the earth, when it receives the invocation of God, is no longer common bread, but the Eucharist, consisting of two realities, earthly and heavenly; so also our bodies, when they receive the Eucharist, are no longer corruptible, having the hope of the resurrection to eternity." + Source: Irenaeus, Against Heresies IV.18.5 (Roberts and Rambaut translation). The argument is running from the table to the body and not the other way round: he is proving the resurrection of the flesh from the practice of the church, to readers who denied the first and observed the second (T5).

(Q) "For the glory of God is a living man; and the life of man consists in beholding God." + Source: Irenaeus, Against Heresies IV.20.7 (Roberts and Rambaut translation). The most quoted sentence he ever wrote, and often loosened into "the glory of God is man fully alive." What he actually says is plainer and harder: a human being, alive, is what God’s glory looks like. Set against teachers who held that the material world was a lesser god’s mistake, it is a whole theology in twenty words.

What the Church Made of Him

(†) The next generations fought their battles with his three weapons: the four Gospels, the rule of faith, and a line of teachers anyone could name. + Within twenty years of his death the method was standard. Tertullian in Carthage borrowed the argument wholesale and sharpened it into a lawyer’s version: the heretics have no right to argue from Scripture at all, because the Scriptures belong to the churches that can show where they got them. Hippolytus at Rome took over the cataloguing of sects. Eusebius, writing his history in the fourth century, leaned on Irenaeus for much of what he knew about the second, and preserved the letters that would otherwise have been lost. What actually got handed on, though, was smaller and more durable than any book: a set of three habits that Christians still use without knowing whose they are. When a claim about Jesus turns up, ask which books it comes from and how early those books are attested. Ask whether it matches the short summary the churches have always taught. Ask who taught it and to whom, out loud, in a place that can be named. Canon, creed, and public succession are the answer Irenaeus assembled, and the modern conversation about lost gospels and suppressed Christianities is still being conducted, on both sides, with tools he laid on the table.

(†) Recapitulation, Christ going back over Adam’s life and getting it right, gave the church a way to say what the incarnation was for. + Irenaeus’s exchange formula, that the Son became what we are so that we might become what he is (T1), turns up again in Athanasius in the fourth century, in almost the same shape, as the summary of why God took a body at all: "For He was made man that we might be made God" (On the Incarnation 54, Robertson translation). In the century of Nicaea that sentence did hard work in the argument for the Son’s full divinity, because a Saviour who is himself less than God cannot make anyone what he is. It remains the ordinary way Eastern Christian writers speak about salvation. The West took a different route and mostly explained the cross through law and debt, a courtroom and a bill paid, which is why recapitulation can sound unfamiliar to readers formed on Anselm and the Reformers. It never went away, though. It runs under the surface of every Christian who reads Adam and Christ as the two heads of the human race, and the twentieth century went back to it deliberately, in Catholic, Orthodox and Protestant theology alike, looking for language about salvation with room in it for the body and the created world and not only for the courtroom. His picture of Adam and Eve as children who had growing still to do has been taken up in the same way, by writers trying to say what the world’s long apprenticeship in suffering could be for.

(†) His work came back twice in the modern era, once from a shelf in Armenia and once from a jar in Egypt. + He wrote in Greek and almost none of the Greek survives. Against Heresies comes down to us complete only in a Latin translation so wooden, so word-for-word, that scholars can often reconstruct the Greek standing behind it, which is exactly what makes a bad translation useful. That was nearly the whole of him for fifteen centuries. Then, in December 1904, an Armenian scholar named Karapet Ter-Mekerttschian found a manuscript in the Church of the Blessed Virgin at Erevan. It contained an Armenian version of Books 4 and 5 and, bound in with them, a short work that had been known only by its title, from a single line in Eusebius: the Demonstration of the Apostolic Preaching. It turned out to be a small catechism, a book of first instruction, written for a friend named Marcianus, and it is the plainest statement of the rule of faith the second century has left us. It had been missing since antiquity. The second recovery was not a book of his but his honesty. Until 1945 the Gnostic systems were known almost entirely from the summaries their opponents wrote, and it was widely assumed that Irenaeus had made his opponents look sillier than they were. Then a jar of codices, that is, bound books rather than scrolls, came out of the sand near Nag Hammadi in Upper Egypt. Among them was the Apocryphon of John, and its account of how the divine world unfolds runs alongside the system Irenaeus describes in his first book (I.29), the one built around a heavenly figure called Barbelo, close enough in order and content that scholars take him to have had a Greek text of the same family open in front of him. It was not this book in the form we now have it. The two diverge on details that abbreviation will not explain, among them where Sophia, the wisdom figure whose blunder sets the making of the world in motion, comes from and what exactly she did wrong. What the discovery settled is the charge that mattered, which is that he had reported his opponents substantially as they were. For a polemicist working under persecution, that is a good afternoon.

(†) Where his own record is weak: he pressed tradition past the evidence, twice. + The man who taught the church to ask for names sometimes accepted a name too readily, and both instances come from the same habit. - The age of Jesus. In his second book he argues at length that Jesus did not die in his early thirties but lived to be nearly fifty (Against Heresies II.22.5-6). His reasons were three: his opponents needed a ministry of exactly one year to make their number symbolism come out, his hearers in John’s Gospel told him "You are not yet fifty years old" (John 8:57), and the elders in Asia who had known John said so. But Luke says plainly that Jesus was about thirty when he began (Luke 3:23), and what Irenaeus has done is to read a hostile remark in an argument as though it were a report of how old Jesus looked, and then back it with a tradition he had no way to check. Almost nobody has followed him here. It is a useful reminder that a second-century witness is a witness and not an oracle. - The vine with ten thousand branches. In his fifth book, arguing for a coming earthly kingdom, he passes on a saying he attributes to Jesus by way of the elders and of Papias (Against Heresies V.33.3-4): vines with ten thousand branches, each branch with ten thousand twigs, each twig with ten thousand clusters, and so on down to the grapes. It is in no Gospel. It reads like the Jewish apocalyptic writing of the period, the visionary literature about the end of the age that was circulating widely in those centuries. And he repeats it as dominical, meaning as a word of the Lord himself, on no stronger ground than that Papias wrote it down and Papias had heard John. His own criterion, that a teaching should be publicly traceable, would have caught this one. Neither failure touches the arguments he is remembered for, and both are on the record because he was scrupulous about naming his sources. That is worth something too: he told his readers where he got it, and so his readers could tell that he was wrong.
