Iglesia de Dios
The Worldwide Church of God arose from the Seventh Day churches. The personal ministry of Herbert W. Armstrong became the Radio Church of God, which became the Worldwide Church of God. It later splintered into many other churches and groups when the Worldwide Church of God disassociated itself with the Restoration movements and made major attempts to join the Protestant branch of Christianity. The largest of these groups, the Living Church of God and the United Church of God, continue in the tradition of the Worldwide Church of God as it was under the leadership of Herbert W. Armstrong.
