The
Seventh-day Adventist Church is a
Protestant Christian denomination distinguished by its observance of
Saturday, the
seventh day of the week in Christian and Jewish calendars, as the
Sabbath, and by its emphasis on the imminent
Second Coming (advent) of Jesus Christ. The denomination grew out of the
Millerite movement in the United States during the mid-19th century and was formally established in 1863. Among its founders was
Ellen G. White, whose extensive writings are still held in high regard by the church.
