Who are the Sabbatarians in Jordan, whose feasts and holidays coincide with Saturday?

The Seventh-day Adventists are a Christian group whose belief system is centered on theand second coming of Christ. They rely on the teachings of William Miller, who prophesied the end of the world. When his prophecy did not materialize, they announced their belief in the return of Christ at an unspecified time after the resurrection of the dead and the beginning of the millennial age. Among their beliefs are the sanctity of Saturday (Sabbath), and the recognition of Ellen G. White as an inspired prophetess. They believe in the annihilation of the wicked, and they have various activities and branches around the world.
