Marcion of Sinope

← Encyclopedia

Marcion of Sinope (c. 85 – c. 160) was a teacher within early Christianity, active in Rome in the 140s, who taught that the God of the Hebrew Scriptures and the Father revealed by Jesus were two different beings — and who, on that conviction, produced the first known fixed canon of Christian Scripture. The church that took his name spread quickly across the empire and survived for centuries. Almost nothing he wrote survives; he is known chiefly through the men who set out to refute him.

He came from Sinope, a port on the Black Sea coast of Pontus, in the Roman Empire’s northern Anatolian reach, and tradition makes him a wealthy shipowner — a nauclerus, master of vessels on the grain and timber routes of the Black Sea. Epiphanius, writing two centuries later, reports that he was the son of a bishop, a detail no earlier source confirms and later hands may have shaped to sharpen the story of a churchman’s son turned heretic. What is firmer is the arc of his Roman years. Arriving in Rome around 140, he joined the church there and gave it a large sum of money — two hundred thousand sesterces, in the figure the tradition preserves, a gift on the scale of a shipping fortune. In the city he fell in for a time with Cerdo, a teacher from Asia already drawing the Creator-and-Father distinction, but the system that bears Marcion’s name was his own work and far outran his teacher’s.

When his teaching was judged unacceptable he was expelled — by Tertullian’s later reckoning in 144, the date conventionally given, after a hearing before the Roman presbyters — and the money returned. The break was clean and the date became a fixed point in the heresiological calendar: Tertullian counts the years from it as from a catastrophe. There is an older scene, too, that the church remembered. Irenaeus tells that when Marcion met the aged Polycarp of Smyrna and asked whether the old man knew him, Polycarp answered that he knew him for the firstborn of Satan. The line travels with Marcion’s name down the whole later literature; it is the tone in which the church chose to keep him.

The two gods

The reading Marcion brought turned on a single distinction, pressed harder than anyone before him had pressed it. The Creator of Genesis — the god who made the material world, gave the Law, and dealt in justice and wrath — was real, and he was the god the Jewish Scriptures faithfully described. He was not, however, the highest God. Above and beyond him stood a God until then wholly unknown, who had no hand in making this world, owed it nothing, and was bound to it by no covenant: a God of pure goodness and mercy, a stranger to the cosmos and to its maker, who out of unprompted love sent Jesus to rescue humanity from the Creator’s jurisdiction. This is the figure Adolf von Harnack named in the title of his great study — the alien God, the God from outside.

The two were not equals locked in struggle, as in some forms of dualism; the lower god was just rather than evil, competent rather than malign, the legitimate ruler of his own handiwork. But his justice was exactly the problem. Law, judgment, the demand for righteousness and the penalty for falling short — these belonged to the Creator, and from them the good God’s emissary had come to deliver. Salvation, on this account, was not the fulfillment of the Creator’s promises but a rescue out of his economy altogether. The gospel was good news precisely because it announced a God who was not the world’s. The redeemed did not graduate from the Law into a higher law; they were bought out from under it by a power the Law had never named and could not bind.

From the same conviction came an austere bodily discipline. The flesh, the married state, the begetting of children — all multiplied the Creator’s world and extended his claim — and Marcion’s church renounced them. Its asceticism was not a counsel of perfection laid over an ordinary Christian life but the practical face of its theology: to be saved from the maker of bodies was, as far as possible, to stop making more. The Christ who did the saving had, for the same reason, no true birth and no true flesh. He appeared in the synagogue at Capernaum already grown, a manifestation rather than an infant, and only seemed to suffer and die — the docetism that follows once the good God is held to have no traffic with matter and the Creator alone owns the territory of bodies and pain.

The cut canon and the Antitheses

From the two-gods reading followed Marcion’s most consequential act. Holding the Hebrew Scriptures — what the church would come to call the Old Testament — to be the truthful record of the lower god and binding on no Christian, he rejected them entirely — not as forgeries but as the authentic book of the wrong deity — and assembled in their place a body of writings he held to be genuinely the good God’s. That collection had two parts. The first was a single gospel, the Evangelion, an edited version of Luke stripped of the infancy narrative and of the passages that root Jesus in the Creator’s promises to Israel. He admitted one gospel only; the Jewish-Christian Gospel of Matthew, with its genealogy tracing Jesus to Abraham and David and its insistence that he had come to fulfill the Law and the prophets, was precisely the kind of text his system could not hold, and it has no place in his canon. The second was the Apostolikon, ten letters of Paul, whom Marcion regarded as the one apostle to have grasped the gospel uncorrupted — the others, on his reading, having relapsed into the Creator’s Law. He arranged the letters with Galatians at the head, the epistle in which Paul’s quarrel with the Law and with the Jerusalem apostles is sharpest: Galatians, the two to Corinth, Romans, the two to Thessalonica, the letter he called Laodiceans (the church’s Ephesians), Colossians, Philippians, and Philemon. The Pastoral Epistles he did not include.

To this body of texts he prefixed his own Antitheses, a catalog of contradictions between the two Testaments meant to prove the two gods by laying their words side by side: the Creator who hardens hearts and orders slaughter against the Father who forbids resistance; the god of an eye for an eye against the gospel of the turned cheek; the maker who pronounced his world good against the stranger who came to undo it. The book is lost, like nearly all of Marcion’s writing, surviving only in the fragments his enemies quoted to refute. But its method is legible in the wreckage: not allegory, which the church used to reconcile the Testaments, but the flat juxtaposition that makes reconciliation impossible. Where Origen would later read the harsh passages of the older Scripture as veils over a spiritual sense, Marcion read them as meaning exactly what they said — and concluded that what they said could not be the speech of the Father of Jesus.

Whether this collection prompted the wider church to fix its own canon is a genuinely contested question, and the chronology will not settle it cleanly. Harnack held Marcion to be the first to conceive of a Christian canon at all, the maker of a Bible that forced the church to make one in answer; Hans von Campenhausen argued more narrowly that Marcion compelled the church to face the question of which new writings carried authority and on what ground. Others hold that collections of gospels and of Paul’s letters were already circulating and gaining weight, so that Marcion accelerated and sharpened a process rather than originating it. What is not in dispute is that his list is the earliest fixed, exclusive collection of Christian Scripture on record — a closed canon with a hard edge, defined as much by what it shut out as by what it let in.

The hostile witnesses

His opponents are the reason any of this is known in detail, and the reason it is known in the shape of an accusation. Justin Martyr, writing while Marcion was still alive and teaching, noted that the man had won followers across the whole human race and devoted a lost treatise to him. Irenaeus answered him in the great catalog of heresy that is Against Heresies. Tertullian, a generation later, gave him five whole books — Adversus Marcionem, the fullest refutation of any early Christian teacher to survive, and the densest single source for what Marcion actually held, since Tertullian argues by quoting in order to overturn. Hippolytus and Rhodon wrote against the Marcionites as well, and Epiphanius, two centuries on, preserved in his Panarion a working list of the Apostolikon and notes on the edited gospel that let scholars reconstruct the canon Marcion cut. Clement of Alexandria and Origen engaged him in passing. Between them these writers fixed his reputation as the arch-heretic of the early church — a verdict delivered in their voice, by the side that won, about a man whose own books they ensured would not come down.

The recovery of a lost teacher

Because Marcion’s own books vanished, the modern study of him is an exercise in reconstruction from hostile quotation — a discipline that has reshaped his figure more than once. The decisive modern intervention was Adolf von Harnack’s Marcion: Das Evangelium vom fremden Gott (Leipzig, 1921; expanded second edition 1924), which gathered the patristic fragments into a full reconstruction of the Antitheses and the canon and argued for Marcion as a genuine theologian and the first builder of a Christian Bible. The gnosis.org library text on Harnack’s reading preserves the broad lines of that interpretation, which dominated the field for most of the twentieth century. Hans von Campenhausen’s Die Entstehung der christlichen Bibel (1968; English The Formation of the Christian Bible, 1972) made the canon question central, casting Marcion as the catalyst who forced the church to define which new writings carried authority.

The last generation has revisited nearly every term of Harnack’s picture. Sebastian Moll’s The Arch-Heretic Marcion (Wissenschaftliche Untersuchungen zum Neuen Testament 250; Tübingen: Mohr Siebeck, 2010) relocates the origin of Marcion’s system in the Antitheses and his reading of the wrathful Creator, rather than in a prior devotion to Paul, and reads him less as a proto-reformer than as a stark and consistent dualist of his own kind. Judith M. Lieu’s Marcion and the Making of a Heretic: God and Scripture in the Second Century (Cambridge: Cambridge University Press, 2015) is the most thorough recent reconstruction, attentive to how much of the heretic is the artifact of the heresiologists who built him as a foil. The text of his cut gospel and letters has been independently reconstructed by Jason BeDuhn in The First New Testament: Marcion’s Scriptural Canon (Salem, OR: Polebridge, 2013), and the competing nineteenth- and twentieth-century reconstructions of the Apostolikon — Zahn, van Manen, Harnack — have themselves been collated and published as open scholarly datasets in the Journal of Open Humanities Data, so that the very fragments can be compared edition against edition. A minority current, associated with Markus Vinzent, presses the reconstruction to its limit and argues that Marcion’s gospel preceded the canonical four rather than abridging Luke — a position most scholars reject, but one that measures how unsettled the relation of his text to the church’s gospels remains. The primary witnesses on which all of this rests — Justin, Irenaeus, Tertullian, Epiphanius — are gathered, in their character as the heresy-hunters’ record, in the older survey of the Gnosis according to its foes.

A dualist, but not a Gnostic

The resemblance to the Gnostic teachers of the same period is real and was noted at once: the demotion of the Creator, the alien high God, a Christ who only seemed to take flesh. The heresiologists filed Marcion in the same rank as Simon Magus and the Valentinian schools and treated the whole as one contagion. The identity does not hold. Marcion built no elaborate hierarchy of emanations, no pleroma of paired aeons spilling downward from the Father, no fallen Sophia whose error produced the maker of the world. He taught no secret saving knowledge reserved for initiates and no myth to be decoded. His appeal was to the plain antithesis of Law and gospel, set out in a book anyone could read, and his church was an open, ascetic, Scripture-reading body with its own sacraments and its own clergy — a rival church, not an inner circle. The Gnostic was saved by knowing; the Marcionite was saved by being bought out.

That difference is why his church behaved as it did. It planted congregations from Italy to the Syrian and Mesopotamian East; it endured, in some regions, into the fifth century and beyond, long after the Valentinian groups had thinned; and it remained recognizably a church rather than a school, with a canon read aloud, a baptism, and a discipline. Centuries later the medieval Cathars would set a good God against the maker of this world in a way that distantly rhymes with Marcion’s — but theirs was a cosmic war of two eternal principles fed by Eastern dualist channels, not Marcion’s quiet demotion of a just Creator who never rose to the level of an enemy. The kinship is one of family resemblance across many removes, not of descent.

What gave the system its grip, and what cost it the church, was the same single stroke. By reading the older Scripture as the truthful book of a lower god, Marcion freed the gospel of its harshest difficulties at one cut — no more straining to make the wars of Joshua speak of mercy, no more allegory to soften the Law — and bought that freedom at the price of two gods and a Christ with no real body. The canon he assembled was that reading made into a book: a gospel purged of the Creator’s promises, an apostle held alone to have understood, and between the Testaments not a bridge but a list of contradictions. The church that prevailed kept both Testaments and one God and read the seam between them as continuity; Marcion kept one Testament and two gods and read the seam as a break. Everything else he is remembered for follows from which way he cut.
