Millenarianism

the doctrine of or belief in a future (and typically imminent) thousand-year age of blessedness, beginning with or culminating in the Second Coming of Christ. It is central to the teaching of groups such as Plymouth Brethren, Adventists, Latter-day Saints (Mormons), and Jehovah's Witnesses.  Dictionary.Com

 

Millenarianism or millenarism is the belief by a religious, social, or political group or movement in a coming fundamental transformation of society, after which "all things will be changed". Millenarianism exists in various cultures and religions worldwide, with various interpretations of what constitutes a transformation.  These movements believe in radical changes to society after a major cataclysm or transformative event.

Both millennialism and millenarianism refer to "one thousand". They both derive from the Christian tradition. Neither term strictly refers to "one thousand" in modern academic usage.

Millenarianism is used to refer to a more cataclysmic and destructive arrival of a utopian period as compared to millennialism which is often used to denote a more peaceful arrival and is more closely associated with a one thousand year utopia.

Christian millennialism is part of the broader form of apocalyptic expectation. A core doctrine in some variations of Christianity is the expectation that the Second Coming is very near and that there will be an establishment of a Kingdom of God  on Earth.   According to an interpretation of biblical prophecies in the Book of Revelation, this Kingdom of God on Earth will last a thousand years (a millennium) or more.  Wikipedia

 

millennialism, the belief, expressed in the book of Revelation to John, the last book of the New Testament , that Christ will establish a 1,000-year reign of the saints on earth (the millennium) before the Last Judgment. More broadly defined, it is a cross-cultural concept grounded in the expectation of a time of supernatural peace and abundance on earth.

Millennialism offers a version of the fundamental eschatological belief that at the end of time (the “End,” or “Endtime”) God will judge the living and the resurrected dead. This belief in ultimate divine justice provides a rationale for theodicy, the reconciliation of God’s goodness with the existence of evil in the world. In providing solace for the suffering of countless generations of believers—Jews, Christians, Muslims and Buddhists—millennialism has had immense appeal in every age. Although its name comes from the 1,000-year period mentioned in the Revelation to John, millennialism is primarily concerned with the earthly nature of the coming “new world.” This radical transformation promises an end to existing institutions of power and, therefore, infuses millennial beliefs with a revolutionary quality that threatens those in authority.  Britannica

Adventism

Adventism is a branch of Protestant Christianity that believes in the imminent Second Coming (Second Advent) of Jesus Christ.  It originated in the 1830s in the US  during the Second Great Awakening when Baptist preacher William Miller first publicly shared his belief that the Second Coming would occur at some point between 1843 and 1844. His followers became known as Millerites. After Miller’s prophecies failed, the Millerite movement split up and was continued by a number of groups that held different doctrines from one another. These groups, stemming from a common Millerite ancestor, collectively became known as the Adventist movement.  Wikipedia

Adventist, member of any one of a group of Protestant Christian churches that trace their origin to the US in the mid-19th century and that are distinguished by their emphasis on the belief that the personal, visible return of Christ in glory (i.e., the Second Coming  is close at hand, a belief shared by many Christians. While most Adventist groups remain relatively small, the Seventh-day Adventist Church  has become a significant global body, with congregations in more than 200 countries and a membership of more than 14 million.

Adventism is rooted in the millennial expectations recorded in the Bible.  From their biblical study, the Adventists came to believe that, at the Second Coming, Christ will separate the saints from the wicked and inaugurate his millennial (1,000-year) kingdom. The Adventists’ emphasis on the Second Coming led many of them to predict the date of its occurrence.
