Chiliast, also known as a millenarian, refers to someone who holds the belief in a thousand-year reign of Christ mentioned in the Book of Revelation. The term "chiliast" is derived from the Greek word "chilioi," meaning "thousand." However, there are other synonyms used to describe people who share this belief system. These include adventists, who focus on the second coming of Christ and the establishment of his kingdom on earth; pre-millennialists, who believe in Christ's return before rendering judgment; and post-millennialists, who anticipate the arrival of Christ after his Kingdom is established on Earth. Some people might also use the term "apocalyptic" to describe these beliefs. While the terms may vary slightly, they all refer to the belief system centered on a literal interpretation of the Bible's prophetic texts.
