Continuity Theology

The Old and New Testaments reveal the same God — wrath and love appear in both.

The Story

Continuity theology is so widely held that most Christians have never heard a name for it — it is simply the assumption that the God of Genesis and the God of the Gospels are one and the same, that the fierce God who drowned the world and the tender God who wept at a tomb are not two beings but one. On this view the wrath and the love are both real, both belong to the same character, and the work of faith is to hold them together rather than to choose between them.

The position became a deliberate doctrine, rather than an unexamined habit, the moment someone denied it. Around the year 144 the shipowner Marcion of Sinope argued in Rome that the Hebrew scriptures and the Christian gospel described different deities altogether: a lower, “righteous” creator-god of law and judgment, and a higher, previously unknown God of pure mercy revealed by Jesus. Marcion assembled a work called the Antitheses, lining up the harsh creator against the gentle Father, and edited his own canon — a single Gospel and ten letters of Paul — stripped of what he took to be Jewish corruption.

The mainstream response was to insist, emphatically, on continuity. Irenaeus of Lyons in Against Heresies and Tertullian in his five books Against Marcion built much of their case on a single claim: the Creator and the Redeemer are the same God, and the Old Testament is not a record of a rival deity but the first act of one continuous story. This conviction was folded into the early “rule of faith” and stands behind the creeds, which open by confessing one God, “maker of heaven and earth,” before moving to Christ.

From there continuity theology became the default of nearly every tradition — Catholic, Eastern Orthodox, Oriental Orthodox, Protestant of every stripe, and most Biblical Unitarians, who though they read the relationship between Father and Son very differently still affirm one God across both Testaments. The disagreements that remain are mostly internal: how the covenants relate, how much of the Mosaic law still binds, whether God’s wrath is an emotion or a metaphor. The basic unity of the divine character is the rare point on which almost everyone agrees.

Which is exactly why it deserves examination. A claim held by nearly everyone is rarely scrutinized, and the tensions it papers over — between herem warfare and “love your enemies,” between a law called “holy” and a law Christians have “died to” — are real and have never been fully resolved. Continuity is the consensus. It is not therefore obvious.

Who Draws the Line

No council ever condemned continuity theology, because it was the position the councils were defending. The line here runs the other way: it is the denial of continuity that gets condemned. Marcion was expelled from the Roman church and his teaching anathematized by the broad consensus of the second- and third-century writers — Irenaeus, Tertullian, and later heresiologists — who treated “one God, creator and redeemer” as a non-negotiable boundary of the faith.

Yet continuity theology is contested at its edges by people who fully accept it in principle. Marcionite instincts recur whenever a Christian quietly files the “God of the Old Testament” under wrath and the “God of the New” under love — a reflex the scholar Marc Zvi Brettler and others have noted is still common in the pews, even among those who would never name Marcion. And the traditions that affirm continuity still divide sharply over what it requires: dispensationalists, covenant theologians, Lutherans with their law-gospel distinction, and Torah-observant Messianic believers all agree the God is one while disagreeing about whether the commands carry forward. The unity of God is affirmed; the unity of the program is where the arguing starts.

Why You Might Accidentally Believe This

The honest route to continuity theology is the desire not to edit. Once you start deciding which portrait of God is the “real” one — keeping the mercy, discarding the judgment — you have made yourself the authority over the text rather than its reader. Continuity is the refusal to do that. It takes the whole Bible at once and says: if the same scriptures that record the love also record the wrath, then the love and the wrath both belong to the God being described, and my discomfort is not a license to cut.

It also flows from simple narrative reading. The New Testament writers plainly thought they were continuing a story, not starting a new one. They quote the Hebrew scriptures constantly, call them holy, and present Jesus as the fulfillment of promises made centuries earlier. If you read the Bible as one book — which is how it has been bound, read, and preached for most of its history — continuity is not a doctrine you adopt so much as the shape the material already has.

The Strongest Case For This View

The most direct argument is that the New Testament refuses to hand wrath to the Old and love to the New. Jesus himself escalates judgment language — warnings of Gehenna, the millstone, the outer darkness — and the book that closes the canon, Revelation, contains some of the fiercest images of divine wrath anywhere in scripture. Meanwhile the Hebrew scriptures are saturated with covenant love: Exodus 34:6 calls God “merciful and gracious, slow to anger, and abounding in steadfast love,” a self-description Israel repeats again and again. The clean split simply does not survive contact with the text.

Jesus also explicitly anchors himself in the older revelation. In Matthew 5:17-18 he says, “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them,” adding that not the smallest stroke will pass away. Paul, for all his arguments about freedom from the law, calls it “holy, and the commandment holy and righteous and good” in Romans 7:12. The earliest Christians did not experience their faith as a break with Israel’s God but as the next chapter of his dealings with it.

Continuity also has a moral logic its defenders prize: a God who is only ever gentle is, in the end, indifferent. Wrath, on this reading, is not the opposite of love but love’s response to what destroys the beloved — God’s anger at oppression, idolatry, and bloodshed is of a piece with his care for the oppressed. To remove the judgment is to remove the seriousness with which God takes the world. The two attributes, held together, describe one coherent character rather than a contradiction.

The Strongest Case Against

The sharpest objection is the one Marcion pressed and that no amount of consensus has fully silenced: some Old Testament texts are not merely stern but morally appalling, and harmonizing them with “love your enemies” requires real strain. The command in Deuteronomy and Joshua to devote whole populations to destruction — herem — including women and children, sits very awkwardly beside the Sermon on the Mount. Marcion’s antitheses lined up the God who ordered slaughter at Jericho against the God who said to love one’s enemies, and many sincere readers since have felt the force of the contrast even while rejecting his solution.

There is also the matter of the law itself. The same Paul who calls the law holy says in Romans 7:4 that Christians “have died to the law through the body of Christ,” and elsewhere treats large portions of the Mosaic code — circumcision, food laws, festivals — as no longer binding. If the God is one and the law is holy, why is so much of it set aside? The continuity claim has to absorb a sharp discontinuity in practice, and the various solutions (the law was a temporary tutor, or divided into moral and ceremonial parts) are themselves later constructions, not obvious from the text.

Critics in the Marcionite tradition, and some modern readers troubled by violent texts, argue that continuity theology survives not because it resolves these tensions but because it forbids the one move that would resolve them — namely, treating the harsher portrait as a flawed human projection. The doctrine’s strength, its refusal to edit, is also its cost: it commits the believer to defending texts that, on their face, depict God commanding atrocity.

What the New Testament Actually Says

The New Testament’s own posture is, unmistakably, continuity — and it complicates the claim at the same time. Jesus treats the Hebrew scriptures as the word of God and reasons from them constantly, yet in the antitheses of Matthew 5 he repeatedly says “You have heard that it was said… but I say to you,” and in Matthew 5:38-39 he takes the lex talionis — “An eye for an eye and a tooth for a tooth,” a principle drawn straight from the Torah — and tells his hearers instead to “not resist the one who is evil” but to turn the other cheek. Whether this is fulfillment, intensification, or quiet correction of the older command is precisely the question the text leaves open.

Paul embodies the same doubled posture. He defends the law’s holiness in Romans 7:12 and grounds the gospel in the promises to Abraham, while arguing across Galatians and Romans that the believer is no longer “under” the law. The continuity is real; so is the rupture. The New Testament writers clearly believed in one God across both covenants, but they did not hand later readers a tidy theory of how the wrathful and merciful portraits, or the binding and superseded commands, fit into a single frame.

So the data underdetermines the dispute. The texts rule out Marcion’s two gods — the New Testament never describes the creator as a rival deity, and it never disowns Israel’s scriptures. But they do not deliver a finished account of how to read the violence, or how the love and the wrath cohere, and that unfinished work is what every tradition, in its own way, is still doing.
