Flip to the front of almost any Bible and you’ll find a table of contents split into two halves. Old Testament, New Testament. Most of us never ask who decided there should be a second list at all, or why the first one stayed.
The answer runs through a rich shipowner from the Black Sea coast named Marcion. In the second century he drew up the first Christian canon we know of, a short list of books he considered authentic. He left out the entire Jewish scripture on purpose, because he’d concluded it was the word of a different God.
Rome’s church threw him out for it. Then it spent the next several generations answering him, and the Bible on your shelf is partly the result. I’ve been reading Bart Ehrman and Hans Jonas on Marcion this week, and he’s a stranger and more sympathetic figure than his reputation suggests.
A Shipowner in Rome
According to Ehrman, Marcion grew up in Sinope, a port on the southern shore of the Black Sea in what’s now Turkey. He made a fortune in shipping. Tradition says his own father was the local bishop and excommunicated him for his ideas, although Ehrman flags that story as “allegedly.”
Around the year 139 Marcion moved to Rome and made a huge donation to the church there. He spent about five years studying and writing. Then, in 144, he asked the leaders of the Roman church to meet and endorse his views. Ehrman calls it the first church council of any kind that we know about.
It went badly. The elders found his teaching repugnant, expelled him, and gave back his money. Marcion went east into Asia Minor and started founding churches of his own, and they lasted. Marcionite congregations were still around for centuries after his death around 160.
Two Gods, One Bible
Marcion’s starting point was the apostle Paul, whom he thought was the only apostle who had understood Jesus. Paul had drawn a hard line between the law of Moses and the gospel of grace. Marcion pushed that line as far as it would go. If the gospel and the law were opposites, he reasoned, they couldn’t come from the same God.
So he split them. One God made this world, chose Israel, and handed down the law.
That God was just, in the narrow sense of an eye for an eye, and Jonas describes him as severe and a little petty while stopping short of calling him evil. The other God, the Father of Jesus, had nothing to do with making the world at all. He was pure mercy, and until Jesus showed up nobody had any idea he existed.
Marcion laid this out in a book called the Antitheses, which set Old Testament passages beside lines from the gospel. Ehrman gives a few of the pairings.
The God of Jericho ordered his people to destroy their enemies, while Jesus told his followers to love theirs. In 2 Kings, a crowd of boys mocks the prophet Elisha and two bears come out of the woods and maul forty-two of them. Jesus, by contrast, said “Let the little children come to me.”
You can see the appeal. Plenty of people today read those same passages and feel the same whiplash. Marcion just refused to smooth it over.
Was Marcion a Gnostic?
For a site like this one, that’s the obvious question, and it’s harder than it looks. Jonas spends pages on it in The Gnostic Religion and lands somewhere in the middle.
In some ways, Marcion is missing most of what makes a Gnostic. He had no elaborate myth about aeons and a fallen Sophia, no secret knowledge, and no allegory. He read his texts literally. Like Paul, he said people are saved by faith, not by gnosis.
Now look at the shape of his universe. A lower creator rules this world, and a higher, unknown God sends a savior to rescue people from it. That’s the same frame you’ll find behind the archons in the Nag Hammadi texts. Jonas concludes that anyone who believed that in the second century has to be counted among the Gnostics, because those ideas were in the air and had clearly shaped him.
Then Marcion added a twist that, to me, is the most interesting thing about him. Jonas sums up his gospel in a single sentence:
“of the alien and good God, the Father of Jesus Christ, who redeems from heavy bonds to eternal life wretched mankind, who yet are entire strangers to him”
Read the last clause twice. In most Gnostic systems, you are a stranger in this world because you secretly belong to the higher one. There’s a spark of light in you, and salvation is a homecoming.
Marcion denied all of that. For him, every part of you, body and soul, was made by the creator and belonged to him.
The good God saved people anyway, with no prior claim on them. Jonas pictures a God who takes in total strangers and leads them to a new father’s house. It’s grace with no backstory, offered to people who were never his.
The Canon He Built
To support all this, Marcion needed a Bible that agreed with him. No official Christian list existed yet. Christians read a loose and shifting collection of gospels and letters, and nobody had drawn a fence around it.
Marcion drew one. According to Ehrman, his canon had eleven books. It held ten letters of Paul (every one in our New Testament except 1 and 2 Timothy and Titus) and one gospel, a version of Luke. The Old Testament was out entirely.
Even those eleven didn’t fully cooperate, so he edited them. Marcion believed earlier copyists had slipped in pro-Jewish material, and he cut what he saw as additions.
The first two chapters of Luke went, since the birth story ties Jesus to David and the prophets. So did the line about God not forgetting a single sparrow. In Marcion’s view the true Father had no hand in nature, so he couldn’t be keeping track of birds.
Jonas notes that this was the first time anyone applied textual criticism to Christian writings, “if in rather a highhanded manner.” It was also the first time anyone conceived of a Christian canon at all.
How Rome Answered
Ehrman makes a point that changed how I think about the whole period. Justin Martyr, writing in Rome around 150, argues at length for his beliefs without naming specific gospels or insisting on a fixed list. Only after Marcion started winning converts do church writers begin talking about which books count.
By around 180, Irenaeus was arguing that there must be exactly four gospels, no more and no fewer. Within a few decades the proto-orthodox churches, the ones whose views would later become official, had settled the biggest question. The Christian Bible would keep the Jewish scriptures.
Jonas puts it bluntly. If “Holy Scripture” still means both testaments today, it’s because Marcion lost. Origen’s later summary of the faith hammers the point home, insisting that one God, “just and good,” gave the law and the prophets and the gospels alike. You can hear Marcion on the other side of every word.
The Ascetic Who Wanted to Annoy His Maker
There’s one more side of Marcion that I find strange. His followers practiced strict abstinence, refusing marriage and limiting what they ate. Clement of Alexandria explains the reasoning:
“By way of opposition to the Demiurge, Marcion rejects the use of the things of this world.”
The goal wasn’t moral purity in the usual sense. The Marcionites didn’t want to help populate the creator’s world or enjoy what he’d made. Hippolytus says Marcion believed he could vex the creator by abstaining. Tertullian, his fiercest critic, reports them sneering at creation as “a grand production, and worthy of its God.”
I don’t think that’s a healthy way to live, and plenty of Gnostics took a gentler view of the body. But it shows how seriously Marcion took his theology. He let it reach all the way into dinner and marriage.
What I’m Taking From Marcion
You don’t have to accept two Gods to learn something from him. These are the three things I keep coming back to.
- Notice when you’re running a private canon. Most of us have a short list of verses or teachers we lean on and a long list we quietly skip. Write down which is which. Marcion at least did it out loud.
- Sit with the hard passages for once. Pick a story that bothers you, the bears in 2 Kings for instance, and read it slowly without resolving it. Marcion’s mistake was cutting the tension too fast. His opponents sometimes erred the other way and explained it away too fast.
- Try his idea of grace as an exercise. Think of someone who has no claim on you, and do something kind for them with no history behind it and no expectation of anything coming back. It’s the closest you’ll get to feeling what Marcion meant.
If you want to see how another second-century teacher handled the same problem of a severe lawgiver, Ptolemy’s Letter to Flora gives the Valentinian answer, and it’s far less drastic than Marcion’s.
Jonas ends his chapter by admitting that Marcion’s message of a new and alien God “will never fail to touch the human heart.” Next time you open a Bible, look at the divider between the two testaments for a minute. It’s there partly because a shipowner from Sinope tried to tear it out.
Marcion’s biography, his canon, the examples from the Antitheses, and the history of canon formation are drawn from Bart D. Ehrman, Lost Christianities: Christian Scriptures and the Battles over Authentication (The Teaching Company, 2012). The summary of Marcion’s gospel, the quotations from Clement of Alexandria, Tertullian, and Origen, and the discussion of Marcion’s place among the Gnostics come from Hans Jonas, The Gnostic Religion (Beacon, 3rd ed., 2001). Bible passages are quoted or summarized from the NIV (2 Kings 2:23-24, Luke 12:6, Luke 18:16).
