Hi Rose,
Off the top of my head, one obvious name is that of
Joseph W. Tkach (March 16, 1927 – September 23, 1995), the appointed successor of Herbert W. Armstrong, founder of the major cult, the Worldwide Church of God.
Tkach became President and Pastor General of the church upon the death of Armstrong in 1986. He spearheaded a major doctrinal transformation of the Worldwide Church of God, abandoning Armstrong's unBiblical, unconventional doctrines:
He denounced belief in British Israelism, also known as Anglo-Israelism, the belief that the "lost ten tribes" of Israel migrated to Europe and then to England and became the primary ancestors of the British people and, thereby, the United State;
encouraged members to seek proper medical treatment (while retaining faith in God as a healer);
the removal of the prohibition of interracial marriage;
the allowance of work on the Sabbath;
the acceptance of the Trinitarian doctrine;
women in the church would be allowed to wear makeup;
publicly declared the Worldwide Church of God a New Covenant church, not bound by the terms of the Old Covenant;
and the acceptance of the validity of other Christian denominations,
officially dropped all doctrines based on Mosaic Law (i.e., the keeping of the Sabbath, the Holy Days, and the dietary laws), making observance of such practices an individual choice.
dropped the requirement of triple tithing, declaring that giving, as taught in the New Testament, was voluntary.
among many other changes, and bringing the church into accord with orthodox evangelical Christianity.
Armstrongism, the abandoned teachings and doctrines of Herbert W. Armstrong, who was a former advertiser and ordained preacher of the Church of God of the Seventh Day, had been written by Armstrong after becoming leader of the Worldwide Church of God, and had been erroneously claimed by him and his followers to restore the true Gospel of the Bible - revealed to him by God during his Bible study.
Joseph Tkach's son, Joseph Tkach Jr., continued his father's work of conforming their doctrines to Scripture, After
Joseph Sr.'s death, the WCG reiterated its full acceptance of the doctrinal changes implemented by Tkach and published an apology to current and former members of the church for the negative impact previous doctrines had had on their members.
In 1997 the Worldwide Church of God became a member of the National Association of Evangelicals, representing 45,000 local churches from 40 denominations.
Some WCG ministers and members, rather than accept the doctrinal revisions Tkach had made, left to create dissident renamed splinter groups, retaining Armstrong's original errant doctrines.
On April 3, 2009, The Worldwide Church of God became known in various areas of the world under the name "Grace Communion International," retaining, at that time, 49,000 members.
Joseph Tkach's son, wrote: "My father Joseph W. Tkach has himself submitted to the truth of Scripture. In the face of opposition, he insisted that Jesus Christ is the Lord. He was a humble and faithful servant of Jesus Christ, allowing God to lead him and the Worldwide Church of God to the riches of his grace. By relying on God in faith and fervent prayer, we fully intend to maintain the course on which Jesus Christ has placed us."
In the new creed of the original cult is the following:
"We emphasize the identity of the Christian in Christ:
"As Christians we were given a new identity in Jesus Christ. As his soldiers, his friends and his brothers and sisters, we were equipped with what is needed to lead the good faith struggle - we have it! Jesus promised never to leave or miss us, and if he lives in us, we will never leave him or each other.
We emphasize the power of the gospel:
"Paul wrote: “For I am not ashamed of the gospel; for it is a power of God that saves all who believe in it »(Romans 1,16). People enter God's kingdom by responding to the gospel. In the Worldwide Church of God we advance the kingdom of God. People accept Jesus Christ as their Lord and Savior. They repent of their sins, show their loyalty and loyalty to him, and do his work in the world. With Paul we believe in the gospel and are not ashamed of it because it is the power of God to save all who believe.
We emphasize to honor the name of Christ
"Jesus, who died for us and loves us, calls us to honor him with all our lives. Knowing that we are safe in his love, we are a people committed to honoring him in all our relationships, at home, in our families and in our neighborhood, in our skills and abilities, in our work, in our lives our free time, the way we spend our money, our time in the Church and in our business affairs. Whatever we go through for opportunities, challenges or crises, we are always committed to bringing glory and glory to Jesus Christ."
Ruth Tucker, an evangelical leader and an early supporter of the changes which occurred in the WCG, wrote in an article in Christianity Today that:
"The 'changes'—as they are referred to by insiders—are truly historic. Never before in the history of Christianity has there been such a complete move to orthodox Christianity by an unorthodox fringe church."
