The Seventh-day Adventist Church is a Christian denomination that emphasizes the observance of Saturday, the seventh day of the week, as the Sabbath. Founded in the United States in the mid-19th century, it arose from the Millerite movement, which anticipated the second coming of Christ. The church promotes a holistic approach to health, encouraging a vegetarian diet and healthy living. Central to the beliefs of the Seventh-day Adventists is the concept of the Investigative Judgment, which asserts that Christ is currently reviewing the lives of believers. The church also emphasizes the importance of education, mission work, and community service, operating numerous schools and health institutions worldwide.
