Seventh-Day Adventism is an outgrowth of the nineteenth-century Millerite movement. William Miller was an American preacher who predicted that Christ would return sometime in the early-1840s. Miller’s followers were called Adventists because they were awaiting Christ’s immediate second advent (i.e., “coming”). Miller eventually gave up on his predictions, but some of his followers claimed that the prophecies had been misinterpreted and regrouped under the leadership of Ellen G. White, Joseph Bates, and Hiram Edson. When they adopted the belief that Christians should worship on Saturday, instead of on Sunday, they became known as Seventh-Day Adventists.
