Adventists

Adventism is a branch of Protestantism with origins in the 19th century American Protestant revival known as the Second Great Awakening.

The name refers to belief in the imminent Second Coming (or "Second Advent") of Jesus Christ. William Miller started the Adventist movement in the 1830s. His followers became known as Millerites.

Although the Adventist churches hold much in common, their theologies differ on whether the intermediate state is unconscious sleep or consciousness, whether the ultimate punishment of the wicked is annihilation or eternal torment, the nature of immortality, whether the wicked are resurrected after the millennium, and whether the sanctuary of Daniel 8 refers to the one in heaven or one on earth. The movement has encouraged the examination of the whole Bible, leading Seventh-day Adventists and some smaller Adventist groups to observe the Sabbath. The General Conference of Seventh-day Adventists has compiled that church's core beliefs in the 28 Fundamental Beliefs (1980 and 2005), which use Biblical references as justification.

In 2010, Adventism claimed some 22 million believers scattered in various independent churches. The largest church within the movement — the Seventh-day Adventist Church — is one of the largest Christian churches in the world, with more than 18 million baptized members.

Adventism began as an inter-denominational movement. Its most vocal leader was William Miller. Between 50,000 and 100,000 people in the United States supported Miller's predictions of Christ's return. After the "Great Disappointment" of October 22, 1844 many people in the movement gave up on Adventism. Of those remaining Adventist, the majority gave up believing in any prophetic (biblical) significance for the October 22 date, yet they remained expectant of the near Advent (second coming of Jesus).
