Amillennialism or amillenarism is a chillegoristic eschatological position in Christianity which holds that there will be no millennial reign of the righteous on Earth. Wikipedia

A view in Christian eschatology that rejects the claimed future thousand-year physical reign of Jesus Christ on the earth, in opposition to premillennial and some postmillennial views of the Book of Revelation, chapter 20, claiming instead that the number of years in Revelation 20 is a symbolic number and that Christ's eventual physical reign will be permanent.
