After moving away from premillennialism to amillennialism, Augustine viewed Sabbath rest in the sexta-/septamillennial scheme as “symbolically representative of Eternity.” Moreover, the millennium of Revelation 20 became for him “symbolically representative of Christ’s present reign with the saints.” Richard Landes observed the 4th century as a time of major shift for Christian eschatology by noting that it "marked a crucial moment in the history of millenarianism, since during this period Augustine repudiated even the allegorizing variety he himself had previously accepted. From this point on he dedicated much of his energy to ridding the church of this belief."
