Definition
"Chiliastic" is synonymous with "millenarian." It describes the belief that Christ will reign on Earth for a thousand years, a concept particularly relevant in some interpretations of Christian eschatology. Think of it as a more specific, often religiously-rooted version of millenarianism, focusing on a literal thousand-year reign of Jesus. While "millenarian" can apply to secular beliefs in a golden age, "chiliastic" usually stays within the religious sphere.
