WELS holds an amillennial interpretation of Revelation 20:1-6, understanding the thousand years as symbolic of the church age or the spiritual reign of Christ, not as a future literal period. The passage is interpreted to teach Satan's defeat and binding through Christ's work, the present triumph of Christ's kingdom (spiritually), and the ultimate resurrection and judgment of all people. WELS emphasizes that detailed chronological speculation about the millennium is not necessary or warranted by Scripture.

WELS strict confessional subscription includes the traditional Lutheran understanding that the millennium is not a future earthly kingdom but a symbolic representation of Christ's victory. The focus is on the resurrection of the dead and the final judgment (as affirmed in the Apostles' Creed and the Book of Concord) rather than on millennialism theories.
