Originally known as the Radio Church of God, and then the Worldwide Church of God, Grace Communion International is currently an evangelical Christian Protestant denomination, but it was one of the larger denominations to evolve from the Adventist Movement begun by Walter Miller in the 1930s.
As teachings about the Saturday Sabbath spread within the Adventist community, some accepted the Seventh-day Sabbatarian message but rejected the ministry of Ellen G. White. They also came to believe that the best name for a Christian church was the Church of God. The Adventist Churches of God remained small and splintered through the 1930s.
In 1934, An Adventist preacher by the name of Herbert W. Armstrong began a radio ministry that gained a large following and grew into the Radio Church of God. Armstrong retained the millennial message of the Adventist Movement, and taught a non-Trinitarian theology, a Saturday Sabbath, and the need to practice Hebrew festivals. Several meats were avoided as being unclean, and holidays like Halloween, Easter, and Christmas were not observed.
Added to his radio ministry was a television ministry, both of which had a large following, although his broadcast audience was much smaller than his church membership.
Church membership required attendance at an annual festival, the acceptance of a strict code of behavior, and tithing. Armstrong viewed himself as the apostle-messenger of the Last Days, and claimed absolute authority in matters of the church.
As the Radio Church of God became the Worldwide Church of God, it included several congregations, most of which worshipped in rented buildings or private homes rather than building worship facilities. Garner Ted Armstrong, the founder's son, became the main speaker on the radio and television shows. The church experienced significant growth from 1964 to 1974, but it encountered difficulties in the 1970s. Garner Ted Armstrong was disfellowshipped on four occasions for adultery. On top of these scandals, he took a portion of the membership with him in 1978 when he formed a rival congregation, the Church of God International, but it never flourished. The original church became more unstable when authorities took the side of former members who claimed that church finances were mismanaged.
The senior Armstrong died in 1986, leaving a church with a membership of 12,000, a $200-million budget, and a publication, Plain Truth, with a circulation of eight million copies a month. The Worldwide Church of God was an international ministry with churches in more than a hundred countries
Upon the death of Armstrong, the leadership of the church passed on to Joseph W. Tkach. He called for a review of the church's teachings, and soon began withdrawing some of the church's literature. One by one, the church abandoned all of Armstrong's unique teachings, then moved on to discard most of its Adventist theology and practices. By 1995, the church's theology was that of a mainstream evangelical Protestant church, and became a member of the National Association of Evangelicals. In keeping with its new identity, the church changed its name to Grace Communion International in 2009, although it remains the Worldwide Church of God in the United Kingdom and some other places.
The sharp changes that occurred in the church were not accepted by everyone, as might be expected. Approximately half of its membership has left, the majority joining one of three breakaway congregations: the United Church of God, the Global Church of God, or the Philadelphia Church of God. Other splinter groups include the Church of the Great God, the Living Church of God, the Church of God, the Eternal, the Restored Church of God, or the Church of God, a Worldwide Association. The United Church of God is the largest, but the Philadelphia Church of God most closely approximates the pre-1986 church.
Prior to the death of Herbert Armstrong, there were several splinter groups, the largest being those started by his son, Garner Ted Armstrong: the Church of God International and the Intercontinental Church of God.
Grace Communion International felt the effects of splintering. Hundreds of its paid staff were laid off, its radio, television and other programs were sharply cut back, and educational institution, Ambassador University, was closed in 1997, after having been in operation for more than fifty years. In 1996, Plain Truth Ministries, its publishing arm, separated and no longer has any legal connection to the church.
