The Seventh-day Adventist Church is an evangelical Protestant Christian denomination that grew out of the Millerite movement in the United States during the middle part of the 19th century. In addition to traditional Trinitarian Protestant theology, Seventh-day Adventists place particular emphasis on the seventh day (Saturday) as a Sabbath day of rest. Like their Millerite forebears, Seventh-day Adventists believe that the second advent (second coming) of Jesus Christ is imminent. The church is also known for the following:
- Founder, prophetess, and prolific author Ellen G. White
- Health message including vegetarianism and abstinence from alcohol, tobacco, and caffeine
- Belief in a literal six day creation culminating in a seventh-day of rest
While Adventist theology remains quite similar to its 19th century Protestant roots, one notable exception is the belief that death is a sleep during which the "dead know nothing" (Ecclesiastes 9:5). This doctrine hangs upon the notion that the body and the soul perish together at death and are resurrected as one at the second coming of Jesus.
