The term "Adventist" refers to members of the Seventh-day Adventist Church, a Christian denomination that emphasizes the imminent return of Jesus Christ. Founded in the mid-19th century in the United States, the movement arose from the Millerite revival, which predicted Christ's second coming. Adventists believe in the authority of the Bible and uphold the observance of the Sabbath on Saturday. Adventists promote a holistic approach to health, advocating for a vegetarian diet and healthy living. They also emphasize education and operate a global network of schools and universities. The church is known for its humanitarian efforts and commitment to community service.
