Context_1 : The Seventh-day Adventist Church is a Protestant Christian denomination distinguished by its observance of Saturday, the seventh day of the week in Christian and Jewish calendars, as Sabbath, and by its emphasis on the imminent Second Coming (advent) of Jesus Christ. The denomination grew out of the Millerite movement in the United States during the mid-19th century and was formally established in 1863. Among its founders was Ellen G. White, whose extensive writings are still held in high regard by the church. Context_2 : The Seventh-day Adventist Commentary Reference Series is a set of volumes produced primarily by Seventh-day Adventist scholars, and designed for both scholarly and popular level use. It includes the seven-volume Seventh-day Adventist Bible Commentary, the two-volume Seventh-day Adventist Encyclopedia, as well as the single volumes Seventh-day Adventist Bible Dictionary, Seventh-day Adventist Bible Students' Source Book and Handbook of Seventh-day Adventist Theology. The series is published by the church-owned Review and Herald Publishing Association. Context_3 : The Branch Davidians (also known as "The Branch") are a religious group that originated in 1955 from a schism in the Davidian Seventh-day Adventists ("Davidians"), a reform movement that began as an offshoot from the Seventh-day Adventist Church ("Adventists") around 1930. Some of those who accepted the reform message had been removed from membership of the Seventh-day Adventist Church because of their supplemental teachings. Today, the original Davidian Seventh-day Adventists and the Branch Davidian Seventh-day Adventists are two different and distinct groups. The doctrinal beliefs differ on major teachings such as the Holy Spirit and Its nature, and the feast days and their requirements. Both groups have disputed the relevance of the other's spiritual authority based on the proceedings following Victor Houteff's death. From its inception in 1930, the reform movement believed themselves to be living in a time when Biblical prophecies of a final divine judgment were coming to pass as a prelude to Christ's Second Coming. Context_4 : The Millerites were the followers of the teachings of William Miller, who in 1833 first shared publicly his belief that the Second Advent of Jesus Christ would occur in roughly the year 1843–1844. Context_5 : The True and Free Seventh-day Adventists (TFSDA) are a splinter group formed as the result of a schism within the Seventh-day Adventist Church in Europe during World War I over the position its European church leaders took, whose most well known leader was Vladimir Shelkov. TFSDA members are part of the Sabbatarian adventist movement, and believe that as a result of the decisions the European church leaders took, the Seventh-day Adventist Church had apostatized and had become "Babylon". The group related its origins to the Seventh-day Adventist Reform Movement which formed in Germany during the period of World War I, when its European church leaders determined it was permissible for Adventists to bear arms and serve in the military, and to disregard the Sabbath during the war, which went against what the church believed. The Seventh Day Adventist Reform Movement formed as the result of a schism within the Seventh-day Adventist Church in Europe during World War I over the position its leadership took on Sabbath observance and in committing Seventh-day Adventist Church members to the bearing of arms in military service. Context_6 : Davidian Seventh-day Adventist is an American offshoot of the Seventh-day Adventist Church that has been fiercely critical of the Adventist Church. The late Victor Houteff, a Bulgarian immigrant living in California who joined the Seventh-day Adventist church in 1919, founded the offshoot in the 1930s. Davidians are best identified and most widely known as The Shepherd's Rod (or The Rod), the group's initial name and a reference to Houteff's first publication, ""The Shepherd's Rod"". The organization itself considers it incorrect to refer to the adherents of the movement by this title.
