The Seventh Day Adventist Church is a Protestant Christian denomination that was founded in the United States in the 1860s. It has approximately 21 million members worldwide, and its beliefs are based on the Bible, including the belief that Jesus Christ is the only begotten Son of God and the only Savior of the world. The Adventists do celebrate Christmas, but they also have their own unique beliefs and practices that set them apart from other Christian denominations. For example, the Adventists believe in a literal interpretation of the Bible and observe the Sabbath on Saturday instead of Sunday. They also believe that Jesus will return to Earth
