The Seventh-day Adventist Church (abbreviated "Adventist") is a ProtestantChristiandenomination which is distinguished mainly by its observance of the period between Friday sunset and Saturday sunset, the "seventh day" of the week, as the Sabbath; along with the soon Second Coming of Jesus Christ. The denomination grew out of the Millerite movement in the United States during the middle part of the 19th century and was formally established in 1863. Among its founders was Ellen G. White, whom Adventists consider a prophet, and whose numerous writings are still held in high regard by the church.
Premillennialism in Christian eschatology is the belief that Christ will literally reign on the earth for 1,000 years at his second coming. The doctrine is called premillennialism because it views the current age as prior to Christ’s kingdom. It is distinct from the other forms of Christian eschatology such as amillennialism or postmillennialism, which view the millennial rule as either figurative and non-temporal, or as occurring prior to the second coming. Premillennialism is largely based upon a literal interpretation of Revelation 20:1-6 in the New Testament which describes Christ’s coming to the earth and subsequent reign at the end of an apocalyptic period of tribulation. It views this future age as a time of fulfillment for the prophetic hope of God’s people as given in the Old Testament.
