Often called “amillenialism” I find the term “millenialism” more helpful. The main reason for this is the fact that by using the prefix “a” to “millenium” appears to negate the fact that there is a millenium. As an advocate of this position, I believe there is a 1000 year reign of Christ. Two qualifiers: 1) We are in the 1000-year reign of Christ (as spoken of in Revelation 20); 2) the 1000 years is not a quantitative 1000 years. That is, as much of the numerology of apocalyptic literature, the 1000 years is symbolic of completeness.This interview (in three parts) by the A-Team blog is helpful as a primer on the doctrine of millenialism:Part OnePart TwoPart ThreeIf you want further study, I would strongly suggest two books:Richard Baukham’s Theology of the Book of RevelationG.K. Beale’s RevelationThe first is great for a bird’s-eye-view of the book and better understanding of apocalyptic literature. The second is worth the money as a resource for you to become familiar with all major positions on the eschaton – and he will argue for “millenialism” as the biblical view.
