History of the Worldwide Church of God

The Founding Years: Herbert W. Armstrong and the Radio Church of God

The Worldwide Church of God (WCG) traces its origins to Herbert W. Armstrong, a former advertising professional from Des Moines, Iowa, who became involved in the Church of God (Seventh Day) during the early 1930s. Armstrong began preaching in rural Oregon, and in January 1934, he launched a radio program called The World Tomorrow on station KORE in Eugene, Oregon. That same month, he began publishing The Plain Truth, a magazine that would eventually reach a circulation of over eight million copies per issue.

Armstrong's organization was formally incorporated as the Radio Church of God in 1933. His message was distinctive: he taught that mainstream Christianity had departed from the original teachings of Jesus and the apostles, and that his church represented the one true continuation of the first-century church. He combined elements from the Church of God (Seventh Day) — including Saturday Sabbath observance and rejection of traditional Christian holidays — with his own teachings on Bible prophecy, British-Israelism, and a unique interpretation of God's plan for humanity.

Growth Through Media: The World Tomorrow Broadcast

Armstrong proved to be a gifted media communicator. Throughout the 1940s and 1950s, The World Tomorrow expanded to more radio stations across the United States, eventually becoming one of the most widely broadcast religious programs in the country. Armstrong's approach was unusual for religious broadcasting: rather than making direct appeals for money on air, he offered free literature and presented his prophetic interpretations of world events in a news-commentary style that attracted listeners who might not have tuned in to conventional preaching.

By the early 1960s, the broadcast had moved to television, and Armstrong's son, Garner Ted Armstrong, became the primary presenter. Garner Ted's polished, professional delivery helped expand the audience significantly. The organization grew rapidly during this period, establishing Ambassador College campuses in Pasadena, California (1947), Bricket Wood, England (1960), and Big Sandy, Texas (1964). The Pasadena campus, with its meticulously maintained grounds and the Ambassador Auditorium — a world-class concert venue completed in 1974 — projected an image of wealth and cultural sophistication.

In 1968, the organization changed its name from the Radio Church of God to the Worldwide Church of God, reflecting its expanding international presence. By the 1970s, the WCG had established congregations across the United States, Canada, the United Kingdom, Australia, the Philippines, and numerous other countries.

Key Doctrines That Defined the WCG

The Worldwide Church of God was distinguished by a set of doctrines that separated its members from mainstream Christianity and, in many cases, from the broader society:

• Saturday Sabbath observance — Members were required to observe the Sabbath from Friday sunset to Saturday sunset, avoiding all work and most secular activities.
• Annual Holy Days — The church observed seven annual festivals based on the Hebrew calendar, including the Feast of Tabernacles, which required members to travel to designated sites for an eight-day gathering each fall.
• Rejection of mainstream holidays — Christmas, Easter, Halloween, Valentine's Day, and birthdays were considered pagan in origin and strictly forbidden.
• British-Israelism — Armstrong taught that the Anglo-Saxon peoples were descendants of the lost ten tribes of Israel, making the United States and Britain central to biblical prophecy.
• Three-tithe system — Members were expected to tithe ten percent of their gross income (first tithe), save an additional ten percent for festival attendance (second tithe), and every third year contribute another ten percent for the church's charitable purposes (third tithe).
• Dietary laws — The church followed Old Testament dietary restrictions, prohibiting pork, shellfish, and other foods classified as unclean.
• Anti-medical stance — For much of its history, the WCG discouraged or prohibited members from seeking medical treatment, teaching that divine healing was the appropriate response to illness.

The 1970s: Crisis and Scandal

The 1970s brought significant turmoil to the organization. Garner Ted Armstrong was removed from the broadcast multiple times due to personal scandals, and internal conflicts over doctrine and governance intensified. In 1974, a group of ministers left the church over disagreements about Armstrong's authority and certain doctrines, taking thousands of members with them.

In 1978, Garner Ted was permanently expelled from the WCG by his father after further allegations of personal misconduct. He subsequently founded his own organization, the Church of God, International.

The most dramatic crisis came in January 1979, when the State of California placed the Worldwide Church of God in receivership, alleging financial mismanagement and misuse of church assets. The receivership lasted several months before being resolved through legislative action and legal challenges. The episode exposed the organization to intense public scrutiny and reinforced critics' concerns about the lack of financial accountability within the church.

Despite these upheavals, Armstrong maintained firm control of the organization. He continued to assert his authority as God's chosen apostle and used The Plain Truth and The World Tomorrow broadcast to maintain influence over the membership.

Armstrong's Death and the Succession Crisis

Herbert W. Armstrong died on January 16, 1986, at the age of 93. Before his death, he appointed Joseph W. Tkach Sr. as his successor — a choice that surprised many within the organization, as Tkach was not among the most prominent ministers. Armstrong reportedly chose Tkach for his loyalty and administrative competence.

Initially, Tkach maintained Armstrong's doctrinal positions and assured members that nothing would change. However, behind the scenes, Tkach and a group of church administrators began reexamining Armstrong's teachings in light of mainstream biblical scholarship. What followed was one of the most remarkable doctrinal transformations in American religious history.

The Doctrinal Revolution of the 1990s

Beginning in the late 1980s and accelerating through the early 1990s, the WCG leadership systematically dismantled Armstrong's distinctive doctrines. The changes included:

• Accepting the doctrine of the Trinity, which Armstrong had rejected
• Abandoning the requirement of Saturday Sabbath observance
• Eliminating the mandatory observance of the annual Holy Days
• Repudiating British-Israelism
• Ending the three-tithe system
• Allowing members to celebrate Christmas and Easter
• Affirming the legitimacy of medical treatment
• Acknowledging that other Christian denominations were legitimate expressions of Christianity

The pivotal moment came on December 24, 1994, when Joseph Tkach Sr. delivered a sermon in Atlanta, Georgia, declaring that the old covenant laws — including Sabbath observance, Holy Days, and dietary restrictions — were no longer binding on Christians. This sermon, later referred to by members as "the big bang," sent shockwaves through the organization. Tkach Sr. died in September 1995 and was succeeded by his son, Joseph Tkach Jr., who continued the reform process.

The Splintering: A Church Torn Apart

The doctrinal changes triggered a massive exodus. By the late 1990s, the WCG had lost approximately two-thirds to three-quarters of its membership and an even larger proportion of its income. Tens of thousands of members left to join newly formed splinter organizations that pledged to maintain Armstrong's original teachings:

• United Church of God (UCG) — Founded in 1995 by a large group of former WCG ministers, UCG became the largest splinter group, adopting a more collegial governance structure than Armstrong's autocratic model.
• Philadelphia Church of God (PCG) — Founded by Gerald Flurry in 1989, even before the major doctrinal changes, PCG positioned itself as the faithful remnant and adopted many of Armstrong's most authoritarian practices. Flurry declared himself a prophet and claimed direct succession from Armstrong.
• Living Church of God (LCG) — Founded by Roderick C. Meredith in 1998, after an earlier stint leading the Global Church of God. Meredith had been one of Armstrong's most senior evangelists.
• Restored Church of God (RCG) — Founded by David C. Pack in 1999, RCG positioned itself as the most doctrinally faithful to Armstrong's teachings while Pack increasingly made grandiose claims about his own prophetic role.

Beyond these major groups, dozens of smaller organizations formed, each led by former WCG ministers who claimed varying degrees of faithfulness to Armstrong's legacy. The splintering produced a complex landscape of competing groups, many of which remain active today.

Grace Communion International: The WCG Renamed

In April 2009, the Worldwide Church of God officially changed its name to Grace Communion International (GCI) to reflect its transformed theology and distance itself from the Armstrong era. The organization joined the National Association of Evangelicals in 1997, a move that would have been unthinkable under Armstrong's leadership.

Today, GCI operates as a small denomination with a fraction of its former membership and resources. The Ambassador College campuses have been sold — the Pasadena campus was sold to developers, and the Big Sandy campus was acquired by another organization. The Plain Truth magazine, once the church's most powerful outreach tool, was eventually transferred to other publishers.

The transformation of the WCG has been studied by scholars of religion as a rare example of a high-control religious group voluntarily reforming its theology and moving toward the mainstream. However, for the tens of thousands of members who lived under Armstrong's system, the history of the Worldwide Church of God remains deeply personal — shaped by the doctrines that governed their daily lives, the community that defined their identity, and the upheaval that eventually forced them to reexamine everything they had been taught.
