Early Christianity

A fish scratched on a wall

In the dim tunnels of the Roman catacombs, among the tombs of the early faithful, a simple sign recurs — a fish, drawn in a few curved strokes. To a Roman passer-by it meant nothing. To those who knew, it was a compressed confession of faith. The Greek word for fish, ΙΧΘΥΣ (ichthys), was read as an acrostic: Ιησοῦς Χριστός Θεοῦ Υἱός Σωτήρ — Jesus Christ, Son of God, Savior. In an age when to be a Christian could mean death, a whole creed was hidden in the outline of a fish, a password one believer could show another without a word.

That image holds the two themes of this chapter. First, that Christianity began as a small, persecuted, and astonishingly diverse movement within the Jewish world of the Roman East — not the vast institution it would become, but a scattering of assemblies meeting in houses, hiding their faith in symbols. And second, that within three centuries this movement would capture the very empire that crucified its founder and executed its apostles, becoming the official religion of Rome. This is the story of how that happened — told, as this archive tells every story, with the tools of history, and with a clear line kept between what the tradition holds sacred and what the historical evidence can show. Both are set down; neither is dressed up as the other.

The historical Jesus: what can be known

On the bare historical facts there is a scholarly consensus of unusual breadth, shared across believers and skeptics alike. A Jewish man named Jesus of Nazareth lived in Roman Galilee in the early first century, was baptized by John the Baptist, gathered followers as an itinerant teacher and healer proclaiming the coming Kingdom of God, and was crucified in Jerusalem under the prefect Pontius Pilate, around 30–33 CE. This much is attested by multiple independent early sources and even, briefly, by non-Christian writers: the Jewish historian Josephus (c. 93 CE) and the Roman Tacitus (c. 116 CE), who records that "Christus" was executed under Pilate. That Jesus existed and was crucified is about as firmly established as anything in ancient history.

Beyond that skeletal outline, historical certainty fades quickly, because our sources are themselves documents of faith. The earliest are the letters of Paul (written c. 50s CE, within a generation of the crucifixion), which say strikingly little about Jesus's life. The Gospels — Mark first (c. 70 CE), then Matthew and Luke (c. 80–90), and John (c. 90–100) — were written decades after the events, in Greek, by authors traditionally but not certainly identified, drawing on oral tradition and (in the case of Matthew and Luke) on Mark and a hypothesized sayings-source scholars call Q. They are theological proclamations, not neutral biographies, and they sometimes disagree on details. What Jesus "really said and did" beneath this layered testimony is the subject of two centuries of the scholarly "quest for the historical Jesus," which has reached no single answer.

The resurrection and the birth of the church

At the center of the faith stands a claim history cannot adjudicate. Jesus's followers, scattered and devastated by his execution, came within a very short time to proclaim that God had raised him from the dead — and this conviction, whatever its ultimate nature, is the engine of everything that follows. Paul preserves what is likely the earliest Christian creed, a formula he says he "received" and passed on (1 Corinthians 15), listing appearances of the risen Christ; it dates to within just a few years of the crucifixion. Historians can establish that the first Christians sincerely believed and proclaimed the resurrection, and that this belief transformed a broken band of Galileans into a missionary movement of extraordinary energy. Whether the resurrection happened, and what it was, lies beyond the historian's reach and within the domain of faith. This chapter records the belief and its world-changing consequences, and leaves the verdict where it belongs.

Paul and the parting from Judaism

Christianity began entirely within Judaism (Chapter 10) — Jesus and all his first followers were Jews, and the earliest community in Jerusalem, led by James the brother of Jesus and by Peter, kept the Torah and worshipped at the Temple. The figure who did more than any other to turn a Jewish messianic sect into a universal religion was Paul of Tarsus, a Pharisee who had persecuted the movement, then experienced a shattering vision of the risen Christ and became its greatest missionary. Paul's radical conviction — that through Christ, Gentiles could be included without becoming Jews, without circumcision or the full Law — opened the movement to the whole Roman world and provoked the first great controversy of the church, resolved (in Acts's account) at the Council of Jerusalem. Over the following decades, hardened by the trauma of the Jewish War and the destruction of the Temple in 70 CE, and by mutual rejection, Christianity and Judaism gradually became two separate religions — a painful "parting of the ways" whose long and bitter legacy the later chapters of this archive will have to reckon with.

The many Christianities

One of the most important corrections modern scholarship has made to the traditional picture is this: there was no single, unified early Christianity. The first two centuries saw a startling diversity of Christian movements, each with its own texts and theology, competing to define the faith. There were Jewish Christians (such as the Ebionites) who kept the Law and saw Jesus as a human Messiah; there was Marcion (c. 140 CE), who rejected the Jewish scriptures and their God entirely, teaching that the alien Father of Jesus was a different, higher God — and who, by publishing his own pared-down scripture (an edited Luke and ten letters of Paul), forced the wider church to begin defining its own canon; there were the various Gnostic Christians, with their secret knowledge and elaborate mythologies (the subject of the next chapter); and there was the "proto-orthodox" stream that would eventually prevail and define what "Christianity" came to mean. The winners wrote the history, and it is only with modern discoveries — above all the Nag Hammadi library of Gnostic texts (reserved for Chapter 17) — that the sheer variety of the earliest movement has come back into view.

The scriptures and the making of a canon

Christianity became a religion of a book, but the book was assembled slowly. The New Testament — 27 documents in Greek — took shape over roughly three centuries. Its core is the letters of Paul (of which about seven are near-universally accepted as authentically his, several others disputed, and the "Pastoral" letters widely regarded as later works written in his name), the four Gospels, the Acts of the Apostles, other epistles, and the apocalyptic Revelation. Alongside these circulated a vast further literature — other gospels, acts, and apocalypses (the apocrypha and the Gnostic texts) — that the emerging church would ultimately exclude. The pressure to draw a firm boundary came partly from Marcion's rival canon; the fourfold Gospel and the Pauline collection were established early, but the full 27-book list was not fixed until the later fourth century (Athanasius's letter of 367 CE is the first to name exactly our canon). Which books were "in" and which "out" was itself one of the great struggles of early Christianity.

Ritual, ethics, and the life of the community

Early Christian worship was intimate and domestic — believers gathered in private houses (the earliest identified Christian building, at Dura-Europos in Syria, is a converted house of c. 240 CE), where they prayed, sang, read scripture, and shared two central rites: baptism, the water-initiation that washed away sin and joined the believer to Christ's death and resurrection, and the Eucharist, the shared bread and wine commemorating the Last Supper as the body and blood of Christ. Their ethics, drawn from Jesus's teaching — the Sermon on the Mount, the command to love God and neighbor, even to love enemies, and a special care for the poor, the sick, and the outcast — were radical in the Roman world, and their practical charity (caring for plague victims, burying the destitute, elevating the status of women and slaves within the community) is widely credited by historians as a real engine of the movement's growth.

The women of the movement

The depth of the record requires attention to a group the later church often wrote out: the women who were central to early Christianity. The Gospels make Mary Magdalene the first witness of the resurrection — the "apostle to the apostles" of later tradition — and Paul's letters name women as coworkers and leaders without apology. In Romans 16 he commends Phoebe, a diakonos (deacon) of the church at Cenchreae whom he trusts to carry the letter itself, and greets Junia, whom he calls "prominent among the apostles" — a woman apostle whose name medieval copyists later masculinized to "Junias," a form unknown in the ancient world, until modern scholarship restored her. Prisca (Priscilla) taught alongside her husband; an order of widows held a recognized place; and women hosted the house-churches in which the movement lived. Only later, in the "Pastoral" letters written in Paul's name (1 Timothy 2), do the sharp restrictions on women's speech and authority appear — evidence that the constraining of women's roles was a development, not the movement's starting point.

Nowhere is a woman's own voice clearer than in the Passion of Perpetua and Felicity. Vibia Perpetua, a young, educated noblewoman of Carthage, was arrested with companions — among them the pregnant slave Felicity — and martyred in the arena in 203 CE. In prison she kept a diary, and it survives: one of the earliest writings by a Christian woman anywhere, a first-person account of her visions, her defiance of her grieving father, her nursing infant, and her calm approach to death. That such a text was written, preserved, and read aloud in the churches is a window onto both the courage of the martyrs and the real, if contested, standing of women in the early faith.

Persecution, martyrdom, and the turn of Constantine

For its first three centuries the church was an illegal or semi-legal sect, and its refusal to worship the Roman gods or offer incense to the imperial cult (Chapter 13) marked Christians as subversive "atheists" and traitors. Persecution was mostly local and sporadic, punctuated by empire-wide waves under emperors such as Nero (who, Tacitus reports, scapegoated Christians for the fire of Rome in 64 CE), Decius, and finally Diocletian in the "Great Persecution" (303 CE). The martyrs who died rather than recant became the heroes of the faith, their courage a powerful witness. Then, astonishingly, the tide turned: the emperor Constantine, crediting a vision of the cross with his victory at the Milvian Bridge (312 CE), legalized Christianity with the Edict of Milan (313), convened the Council of Nicaea (325) to settle the church's disputes over the nature of Christ, and set the faith on the road to dominance. By 380 CE, under Theodosius, Christianity was the official religion of the Roman Empire. The persecuted had become the establishment — a transformation whose consequences run through the rest of this archive.

The birth of the saints

The martyrs did not simply die; they were remembered, and out of that remembrance grew one of Christianity's most enduring institutions. The earliest account of a martyrdom outside the New Testament, the Martyrdom of Polycarp (the aged bishop of Smyrna, c. 155 CE), already shows the pattern forming: after Polycarp was burned, his community gathered up his charred bones, which they called "more precious than gold and costly gems," and laid them in a fitting place — the seed of the cult of relics. They resolved to gather each year on the day of his death, for a martyr's death was reckoned his birthday, his dies natalis, the day he was born into heaven; and this annual graveside commemoration is the origin of the Christian calendar of saints. Long before there were formally canonized saints or grand basilicas, ordinary Christians were keeping the "birthdays" of their dead heroes at their tombs. The veneration of the martyrs, their relics, and their feast-days — which would grow into the vast medieval cult of the saints — begins here, in the age of persecution itself.

The believer's lens

To the Christian, everything turns on a single event: God became man in Jesus of Nazareth, was crucified for the sins of the world, and rose bodily from the dead — and in that resurrection death itself was defeated and a new creation begun. The scattered, terrified disciples were transformed into fearless witnesses precisely because, the faith holds, they met the risen Christ; the church is his living body, the Eucharist his real presence, baptism the believer's own death and rising with him. The kingdom of God has broken into history and will be consummated at his return. From inside, the astonishing spread of the movement — from a crucified Galilean teacher to the faith of an empire in three centuries, through persecution and martyrdom — is itself a kind of testimony: the gospel is true, and the Spirit carried it. The martyrs did not die for a metaphor, and the empty tomb is, to the believer, the hinge on which the world turns.

The skeptical lens

The historian reconstructs the movement as any ancient movement — from texts, dates, and remains — and can establish a good deal: that a Jewish teacher named Jesus was baptized by John, gathered followers, and was crucified under Pontius Pilate around 30 CE, and that his followers soon proclaimed him risen and worshipped him. But the Gospels are theological documents written decades later (Mark c. 70, the others later still), shaped by the faith of the communities that produced them and not eyewitness court records, so the critical scholar weighs them carefully, notes their differences, and distinguishes the "Jesus of history" from the "Christ of faith." The resurrection itself is the boundary of history: that the disciples believed they had seen the risen Jesus is historically robust; whether God in fact raised him is a claim of faith beyond what evidence can establish. And "early Christianity" was strikingly plural — Jewish-Christian, Pauline, Gnostic (Chapter 17), and more — so the "orthodoxy" that won was one strand among several. History marks the boundary; it does not cross it.

Symbology and sacred encoding

The fish and the hidden creed. As we began, the ΙΧΘΥΣ fish was the great encoded emblem of the persecuted church — a symbol that was simultaneously a picture, an acrostic creed (Jesus Christ, Son of God, Savior), and a secret sign. It drew on the Gospel imagery of Jesus making his fishermen disciples "fishers of men" and the miraculous catches, and let believers mark tombs and greet one another in safety.

The monograms of the Name. Christian sacred encoding clustered around the name of Christ. The Chi-Rho (☧) superimposes the first two Greek letters of Christos (Χ and Ρ) — the sign Constantine placed on his soldiers' shields. The staurogram or Tau-Rho (⳨), combining tau and rho, is older still, and remarkably, in the earliest Gospel manuscripts it was used within the word "cross/crucify" as a tiny pictogram of the crucified Jesus — the earliest visual reference to the crucifixion, two centuries before the scene was openly depicted. And the letters Alpha and Omega (Α and Ω), the first and last of the Greek alphabet, encoded Christ's claim in Revelation to be "the beginning and the end."

The reticence of the cross. Strikingly, the cross itself — later Christianity's universal symbol — was rare in the first centuries. To a Roman world that knew crucifixion as the most shameful of deaths, an instrument of torture was not an obvious emblem, and early Christians more often depicted Christ as the youthful Good Shepherd carrying a lamb, or as the praying orant figure, or through the anchor (hope) and the dove (the Spirit and peace). The cross rose to dominance only after Constantine, when crucifixion was abolished and the symbol could be embraced without shame.

666: a number that names an enemy. The most famous piece of encoded meaning in the New Testament is the "number of the beast," 666, in Revelation (13:18), which the text itself frames as a riddle — "let the one who has understanding calculate." Applying Hebrew gematria (letter-values, as in Chapter 7 and 10) to the name Nero Caesar (Hebrew nrwn qsr) yields exactly 666 — and the identification is strengthened by an ancient manuscript variant reading 616, which is what one gets from the Latin form of the name. Most scholars now read the beast as the persecuting emperor Nero, his name encoded to shield the author from Roman eyes: sacred numerology deployed as coded political resistance.

The relic and its image: the Shroud of Turin. No Christian object has been more intensely studied, or more fiercely contested, than the Shroud of Turin — a linen cloth bearing the faint, photographic-negative image of a crucified man, venerated by many as the burial cloth of Jesus. It belongs here as the archive's chief case of a relic claimed to carry sacred meaning, held to the same evidence-honesty standard as everything else. The documented facts: the Shroud appears in the historical record only in the 1350s, in France; in 1988 three independent laboratories radiocarbon-dated samples of it, in a coordinated test, to c. 1260–1390 CE — squarely the medieval period of its first appearance — a result published in Nature. Defenders have contested that dating (arguing the sampled corner was a later repair, or citing a 2022 X-ray study claiming an ancient date), while skeptics note the image is consistent with medieval technique and no forgery method has been definitively shown either. The honest state of the matter: the mainstream scientific verdict, resting on the 1988 radiocarbon test, is that the Shroud is a medieval artifact, while its devotees dispute that verdict and its image remains genuinely unexplained in its method. What is sacred to believers and what the testing establishes are, as always in this book, two different statements — and here they openly conflict.

Connections

Christianity is unthinkable without Second Temple Judaism (Chapter 10) — its scriptures, its messianic and apocalyptic hopes, its God — and it grew up in the religious marketplace of the Roman Empire (Chapter 13), whose imperial cult it defied and whose roads and Greek language it used to spread. Its theology drew deeply on Greek philosophy (Chapter 15): the Gospel of John opens by identifying Christ with the Logos, and the Church Fathers would build Christian doctrine with the tools of Plato and Aristotle. It is the sibling and rival of the Gnosticism and the Roman mystery cults of the next chapters, and of the Rabbinic Judaism forming in the same centuries. Forward, its story dominates much of this archive: the great Christological councils and the making of orthodoxy, the split of East and West, the rise of Islam partly in response to it (Chapter on the early medieval), the medieval church, the Reformation, and the countless movements and mysticisms that flow from it down to the present.
