What Scripture says
The “millennium” (Latin for “a thousand years”) comes from Revelation 20:1–6:
- An angel binds Satan for a thousand years, “so that he might not deceive the nations any longer, until the thousand years were ended” (Revelation 20:2–3, ESV).
- Those who had been martyred for their testimony “came to life and reigned with Christ for a thousand years. This is the first resurrection” (20:4–5).
- After the thousand years, Satan is released, deceives the nations, and is defeated and thrown into the lake of fire (20:7–10).
- The final judgment follows (20:11–15).
This is the only passage in the Bible that mentions a thousand-year reign.
What the evidence says
Interpretation
The three main views
| View | When Christ returns | The millennium is |
|---|---|---|
| Premillennialism | Before the millennium | A future literal reign of Christ on earth |
| Amillennialism | After the millennium (which is now) | The present age, with Christ reigning from heaven |
| Postmillennialism | After the millennium | A future golden age brought about by the gospel’s spread |
Premillennialism reads Revelation 20 as following chapter 19, where Christ returns. So Christ comes first, then reigns on earth for a thousand years. The “first resurrection” (20:5) is a bodily resurrection of believers. There are two forms: historic premillennialism, held by many early Christians, and dispensational premillennialism, developed in the 19th century, which links it with a pretribulation rapture (see 10.8) and a distinct future for Israel (see 10.7).
Amillennialism reads the thousand years as symbolic (see 10.4), representing the whole period between Christ’s first and second comings. Satan was bound at Christ’s first coming (Matthew 12:29, Colossians 2:15), so he can’t stop the gospel spreading to the nations. The “first resurrection” is spiritual new life, or believers reigning with Christ in heaven after death. Revelation’s visions often retell the same period from different angles rather than following in strict order.
Postmillennialism expects the gospel to spread until most of the world is Christianized, ushering in an era of peace and righteousness, after which Christ returns. It was influential among Puritans and in the 18th–19th centuries, linked with missions and social reform.
History
| Period | Main view |
|---|---|
| 2nd–3rd centuries | Premillennialism common (Papias, Justin Martyr, Irenaeus); some disagreed |
| 4th century onward | Amillennialism dominant after Augustine |
| 17th–19th centuries | Postmillennialism influential among Protestants |
| 19th–20th centuries | Dispensational premillennialism spreads, especially in America |
Justin Martyr, around AD 160, held a future thousand-year reign in Jerusalem, but acknowledged that “many who belong to the pure and pious faith” thought otherwise (Dialogue with Trypho 80). Augustine, who once held a premillennial view, later interpreted the thousand years as the church age, and this became the dominant view in Catholic, Orthodox and many Protestant churches.
What all agree on
All three views affirm that Christ will return personally, the dead will be raised, there will be a final judgment, and God will make a new heaven and earth (see 10.2). The millennium debate concerns the order and nature of events, not these core beliefs.
Where they meet
Premillennial, amillennial and postmillennial views all have long histories. The question is unresolved.
What’s still open
The nature and timing of the millennium.
Bottom line
Premillennial, amillennial and postmillennial views all have long histories. It is unresolved, so this is rated Open.
