Postmillennialism

The Story

Postmillennialism is the most relentlessly hopeful of the three classic readings of the thousand years in Revelation 20. It holds that the millennium is not a future cataclysm but a coming era of gospel success: the church, by ordinary preaching and the work of the Spirit, will gradually disciple the nations until the world is, in some meaningful sense, Christianized. Only after this long golden age — “post,” after the millennium — does Christ return in person to raise the dead and judge. Where the premillennialist expects things to get worse until Jesus rescues a faithful remnant, the postmillennialist expects things to get better because Jesus is already reigning and the leaven is already working.

The view has deep roots in the optimistic strands of Reformed and Puritan thought, but it found its most famous American voice in Jonathan Edwards. In his sermons and in the material later gathered as A History of the Work of Redemption, Edwards anticipated a “latter-day glory” in which wars would cease, knowledge would increase, false doctrines would be exploded, and the nations would dwell together as brethren. For Edwards the revivals of his own day were not the end of the story but the first showers of a coming flood.

In the eighteenth and nineteenth centuries this confidence felt almost self-evident. Missionary societies multiplied, the gospel spread across continents, and many Protestants read the expansion of Christendom and the moral reforms of the age as the kingdom visibly advancing. The Princeton theologians inherited and refined the position; B. B. Warfield, perhaps its most rigorous defender, argued from the conquering-Christ vision of Revelation 19:11-21 that the whole interadvental age is “the period of the advancing victory of the Son of God over the world.”

Then the twentieth century happened. The First World War, the Second, the Holocaust, and the Cold War made the language of inevitable progress sound naive, even obscene. Postmillennialism’s influence, already waning since around the American Civil War, collapsed; many of its former adherents quietly migrated to amillennialism, which keeps a present, spiritual reign of Christ but drops the expectation of a literal Christianized golden age. For a few decades the view looked all but extinct.

It did not stay buried. In the 1970s R. J. Rushdoony, Greg Bahnsen, Gary North and the Christian Reconstruction movement revived postmillennialism and welded it to theonomy — the claim that the civil law of Moses still binds modern societies. In their hands the doctrine became not merely a forecast of gospel success but a program for it. That fusion gave postmillennialism fresh energy on the Reformed right, and a distinct, less politicized version persists among writers like Keith Mathison and the broader “optimistic amillennial/postmillennial” stream today.

Who Draws the Line

No ecumenical council ever condemned postmillennialism, and no major confession singles it out by name. The historic creeds affirm that Christ “will come again to judge the living and the dead” without specifying the timing of the millennium, which is precisely why all three positions have lived, often uneasily, inside the same churches.

The contest is therefore intramural rather than conciliar. Dispensational premillennialists reject postmillennialism most sharply, reading Scripture to predict decline and apostasy before the end rather than triumph. Many amillennialists regard it as over-realized — right that Christ reigns now, wrong to expect a visible earthly golden age. Critics across traditions also worry about the theonomic version’s political ambitions. But these are disagreements between brethren over the shape of hope, not anathemas; a Reformed postmillennialist and a Reformed amillennialist can share a pulpit and a communion table.

Why You Might Accidentally Believe This

If you take the Great Commission with full seriousness — “make disciples of all nations” — it is natural to expect that command to actually succeed. Jesus does not say “try to disciple the nations and fail.” If the gospel is the power of God for salvation, and if the Spirit is genuinely at work, why would the long arc of history bend toward defeat? Postmillennialism simply lets the commission mean what it seems to promise.

The view also flows from the parables of the kingdom. A mustard seed becomes the largest of garden plants; a little leaven works through the whole lump. Read these as describing the kingdom’s trajectory in history, and you arrive at gradual, pervasive, world-transforming growth almost without trying. Add the conviction that Christ is reigning now, at the right hand of God, and the expectation of present and increasing victory follows easily.

The Strongest Case For This View

The textual heart of postmillennialism is the present reign of Christ. Paul writes in 1 Corinthians 15:25 that “he must reign until he has put all his enemies under his feet” — an allusion to Psalm 110:1. Postmillennialists stress the word until: Christ reigns through the present age, and that reign is actively subduing his enemies before the end, not merely waiting them out. The conquest is happening in history, not postponed past it.

The kingdom parables of Matthew 13:31-33 supply the mechanism. The mustard seed and the leaven both depict something that starts small and ends large and all-pervasive, growing organically rather than by sudden intervention. Postmillennialists read these as a deliberate portrait of how the kingdom comes: quietly, gradually, irreversibly, until it fills the field and the loaf.

Beyond particular texts, the view appeals to the sheer scope of the Old Testament promises — that the earth will be full of the knowledge of the LORD as the waters cover the sea (Isaiah 11:9), that the nations will stream to Zion, that the Messiah’s government will have no end. Postmillennialists argue these promises demand an in-history fulfillment grand enough to match their language, and that a gospel destined for ultimate failure on earth is hard to square with the confidence of the prophets. Defenders such as Edwards, Warfield, Loraine Boettner, and Keith Mathison have built the case as one of biblical optimism: Christ’s victory is not merely guaranteed at the last day but increasingly visible before it.

The Strongest Case Against

The most immediate objection is that the New Testament repeatedly predicts the opposite of cultural triumph. In 2 Timothy 3:1-5 Paul warns that “in the last days there will come times of difficulty,” with people lovers of self, money, and pleasure rather than God. In the Olivet Discourse of Matthew 24, Jesus foretells wars, famines, persecution, the love of many growing cold, and false christs deceiving even the elect. Critics ask how a steadily Christianizing world fits a portrait of mounting apostasy and tribulation.

Then there is the witness of history itself. The post-World-War disillusionment was not merely a mood; for many it was a refutation. A theology that had read missionary expansion and Western progress as the kingdom advancing seemed unable to account for the trenches, the death camps, and the bomb. If two world wars among ostensibly Christian nations are compatible with the gospel triumphing, opponents argue, then “triumph” has been defined so loosely as to be unfalsifiable.

Premillennialists add an exegetical complaint: postmillennialism, they say, must allegorize the very texts it depends on, treating concrete prophetic and apocalyptic imagery as gradual historical process while ignoring the plain sequence of Revelation 20, where the binding of Satan and the reign of the saints frame a return of Christ that precedes, not follows, the millennium. Amillennial critics press from the other side, charging that postmillennialism over-realizes the kingdom, expecting in history a glory the New Testament reserves for the age to come.

What the New Testament Actually Says

The New Testament genuinely contains both strands, and that is the crux of the dispute. Texts of victory and growth are real — the present reign of 1 Corinthians 15:25, the expanding seed and leaven of Matthew 13:31-33, the global commission of Matthew 28:18-20. So are texts of suffering and decline — the warnings of 2 Timothy 3:1-5, the tribulation of Matthew 24, the beast who is permitted to “make war on the saints and to conquer them” in Revelation 13:7. Any honest reading has to hold these together, and each eschatology is in part a decision about which set governs the other.

The decisive passage, Revelation 20:1-6, is itself contested at the level of genre. Whether the thousand years are a literal future epoch, a symbol of the entire church age, or a coming golden era depends on prior judgments about how apocalyptic literature signifies — judgments the text does not settle for the reader. Nor does the New Testament anywhere offer a timetable correlating gospel success with the date of the return. It assures believers that Christ reigns and will return triumphant; it does not specify whether the road there runs uphill, downhill, or both at once.

This is why the millennial question remains permanently open within orthodox Christianity. The same Bible has nourished Edwards’s confidence and the dispensationalist’s foreboding. The data underdetermine the answer, and sincere readers of equal devotion have walked away with opposite expectations — which is the unresolved tension postmillennialism shares with its rivals rather than escapes.
