A failed doomsday date in 1844 gave rise to a 24-million-member church
William Miller told his followers Jesus would return on October 22, 1844. When nothing happened, most drifted away. A handful reinterpreted the prophecy instead, adopted a Saturday Sabbath, and built what became the Seventh-day Adventist Church, now running over 7,500 schools across more than 215 countries and territories.
The Millerite movement flourished in upstate New York during the 1840s, part of the Second Great Awakening. William Miller used Daniel 8:14 and a rule treating prophetic days as years to forecast Christ's return between spring 1843 and spring 1844. His followers later settled on October 22, 1844, that year's Day of Atonement. The quiet morning that followed went down as the Great Disappointment.
Hiram Edson and others kept Miller's arithmetic but changed its meaning. Daniel's verse, they decided, described Christ entering the most holy place of a heavenly sanctuary, not coming back to Earth. That reading grew into the investigative judgment, a process said to have begun in 1844 in which each person's fitness for salvation is reviewed. The group stayed convinced the return was near, yet refused to name another date.
Keeping Saturday holy came through a chain of influence. Rachel Oakes Preston, a Seventh Day Baptist, persuaded preacher Thomas M. Preble, whose tract in turn won over Joseph Bates, the idea's chief champion. The Sabbath filled the first issue of The Present Truth in July 1849. For roughly two decades the believers were a loose network held together by James White's Advent Review and Sabbath Herald, until formal organisation in 1863. Ellen G. White, whose visions convinced fellow members she had a prophetic gift, became the central figure, and the church still prizes her writings.
Some doctrines match mainstream evangelicalism, such as the Trinity. Others stand apart: soul sleep, annihilationism, a recent six-day creation, and an insistence that body, soul and spirit are one. Members follow Jewish dietary law and are encouraged toward vegetarianism. A General Conference governs a structure of divisions, unions and local conferences. By 2016 baptized membership exceeded 24 million, and the church also runs hospitals, publishing houses, the aid agency ADRA and businesses such as Sanitarium.
