Millennialism

Millennialism (from millennium, Latin for "thousand years"), or chiliasm in Greek, is a belief held by some Christian denominations that there will be a Golden Age or Paradise on Earth in which "Christ will reign" for 1000 years prior to the final judgment and future eternal state (the "World to Come" of the New Heavens and New Earth). This belief is derived primarily from Revelation 20:1–6. Millennialism is a specific form of millenarianism.
