Origin from 1934

An American Protestant denomination founded in 1934 by Herbert W. Armstrong as the Radio Church of God, renamed Worldwide Church of God in 1968. Under Armstrong its doctrine required seventh-day Sabbath and annual Hebrew festival observance, taught British Israelism, the identification of the British and American peoples as descendants of the ten lost tribes of Israel, and rejected the Trinity. After Armstrong's death in 1986, his successor Joseph W. Tkach Sr, and after 1995 Tkach's son Joseph Tkach Jr, led the church through a documented, self-acknowledged reversal of nearly every one of these distinctive teachings, embracing the Trinity, salvation by grace apart from the Old Covenant law, and mainstream evangelical Protestant doctrine. The church joined the National Association of Evangelicals in 1997 and took its current name, Grace Communion International, in April 2009. The reversal cost the church a large share of its membership to splinter groups that kept Armstrong's original teachings, and it remains one of the most thoroughly documented doctrinal transformations of any twentieth century American denomination.

Position on Sexuality

Sourced to the subject's own accountGrace Communion International's own statement of 14 January 2015 defines marriage as between a man and a woman and states no pastor is required to perform any marriage, homosexual or heterosexual, while explicitly opposing verbal or physical abuse of anyone in the LGBT community and framing identity in Christ as taking priority over sexual orientation, a stated welcome that distinguishes this reading from a restrictive one.
Sexuality Position DetailSourced to the subject's own account
Grace Communion International, formerly the Worldwide Church of God, published a statement on its own official site on 14 January 2015 defining marriage as being between a man and a woman and stating that no pastor is required to perform any marriage, homosexual or heterosexual. The same statement declares that, as Christians, the denomination is opposed to verbal or physical abuse of anyone in the LGBT community, and frames a believer's identity in Christ as taking priority over sexual orientation, presenting singleness as a valid spiritual calling rather than a deficiency. The statement does not address ordination of partnered LGBT clergy directly. 6
History
Separation or Divergence
Joseph Tkach Sr's reforms of 1988 to 1995, especially the 17 December 1994 sermon "Understanding the Covenants" that ended the Sabbath and Hebrew festival requirement, prompted an exodus. By the church's own account, hundreds of ministers and roughly 12,000 members left in 1995 alone, most joining or forming splinter groups that preserved one or another of Armstrong's original teachings, a fragmentation into more than a hundred distinct bodies documented at length in David Barrett's scholarly history of the schism. 2 4

From Radio Church of God to Worldwide Church of God

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

Herbert W. Armstrong, born in Des Moines, Iowa in 1892, adopted Sabbatarian and British Israelist teaching after his own 1927 conversion in Oregon, joining and then splitting from an existing Church of God (Seventh Day) ministry. In 1933 he began an independent radio broadcast from a 100 watt station in Eugene, Oregon, first airing 7 January 1934, under the name Radio Church of God, paired with a magazine, The Plain Truth. The ministry grew quickly: Armstrong incorporated the church in 1946, moved its headquarters to Pasadena, California in 1947, and founded Ambassador College the same year to train its ministers.

On 5 January 1968 the church took the name Worldwide Church of God, by which time its doctrine was fully formed and distinctive within American Christianity. It required members to keep the seventh day Sabbath and the annual Hebrew festivals, Passover, Pentecost, Trumpets, Atonement and Tabernacles, as commanded practice rather than optional observance. It taught British Israelism, identifying the British and American peoples as descendants of the ten lost tribes of Israel and reading contemporary geopolitics through that lens. And it rejected the Trinity, teaching instead that the Father and the Son alone were fully divine.

By Armstrong's death on 16 January 1986, weekly attendance had reached roughly 120,000 and annual income approached 200 million dollars, making it one of the larger independent radio ministries built in twentieth century America.

The Tkach Reformation and the Making of Grace Communion International

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

Armstrong's chosen successor, Joseph W. Tkach Sr, began revising doctrine almost immediately, permitting members medical care, cosmetics and birthday celebrations in 1988 that Armstrong had forbidden. The changes accelerated: in 1991 the church revised its teaching on being born again and accepted the Holy Spirit's full divinity, and in 1993 it formally accepted the Trinity. The most consequential change came on 17 December 1994, when Tkach preached a sermon titled "Understanding the Covenants," declaring that the Old Covenant's laws, including the seventh day Sabbath and the annual festivals, were not binding on Christians living under the New Covenant. Through 1995 the church went further still, formally rejecting British Israelism as well. By the church's own account, the reforms cost it heavily: hundreds of ministers and roughly 12,000 members left in 1995 alone, most joining or forming splinter groups that preserved one or another of Armstrong's original teachings, a fragmentation into more than a hundred distinct bodies documented at length in David Barrett's scholarly history of the schism.

Tkach Sr died on 23 September 1995 and was succeeded by his son, Joseph Tkach Jr, who completed the turn toward evangelical orthodoxy. The church joined the National Association of Evangelicals in 1997, and in April 2009 it renamed itself Grace Communion International, the name it carries today as a member denomination of mainstream American evangelicalism.
