Biblical Unitarians do not hold a unified position on Revelation 20:1-6 and millennial theology. Some Biblical Unitarian scholars favor an amillennial interpretation, understanding the 'thousand years' as a symbolic representation of Christ's present reign in heaven and the current age of the church, not a literal future millennium. Others lean toward postmillennialism, interpreting the thousand years as a future extended period of gospel advancement before Christ's final return.

What unites Biblical Unitarians across these eschatological positions is their rejection of certain Trinitarian interpretations specific to Revelation 20. They uniformly deny premillennial rapturism (the idea of a pre-tribulation rapture of the church before a literal thousand-year reign of Christ on earth), viewing this as a modern theological innovation influenced by dispensationalist interpretations that they regard as philosophically problematic. Biblical Unitarians emphasize that millennial theology should not depend on Trinitarian assumptions about the nature of Christ, and that various eschatological frameworks can be compatible with their Christology.
