You may be surprised to learn that 7th-day Adventists do not celebrate Christmas. While other Christians around the world celebrate the birth of Jesus on December 25th, 7th-day Adventists believe that the Bible does not provide any support for the celebration of Christmas. Instead, they focus on observing the seventh day of the week, which they believe to be the true Sabbath. 7th-day Adventists believe that the true meaning of Christmas is not found in the date or the festivities, but rather in the teachings of Jesus and his message of love and hope.
