Millennium, Postmillennial View

Postmillennialism is the eschatological view that Christ will return after (Greek post) the millennium — a long period of spiritual prosperity and gospel triumph during which the church's preaching will progressively Christianize the world and usher in a golden age of righteousness, before Christ's return at the end. The "millennium" of Revelation 20:1–6 is interpreted spiritually: the binding of Satan refers to Christ's victory at the cross restricting his ability to deceive nations (John 12:31; Col. 2:15), and the thousand years are symbolic of a prolonged period of gospel advance rather than a literal thousand-year earthly reign. Postmillennialism was the dominant eschatology of Puritan and Reformed theology in the 17th–19th centuries, providing the theological fuel for missionary movements and social reform. Key texts cited include the Great Commission (Matt. 28:18–20), the Davidic psalms of Christ's universal reign (Pss. 2; 72; 110), Paul's vision of the fullness of the Gentiles and "all Israel" being saved (Rom. 11:25–26), and the growth parables of the kingdom (Matt. 13:31–33). Postmillennialism declined after World War I but has been revived by Christian Reconstructionism (Rushdoony, Bahnsen) and progressive covenantal theology.
