What began with six people at Beaver Dam grew, through Warner's revivalist preaching and the wide circulation of the Gospel Trumpet, into congregations across the American Midwest and beyond within a generation. In 1906 the movement's publishing operation relocated to Anderson, Indiana, which became the center of its administrative and educational life; Anderson University, and the seminary now called Anderson University School of Theology, both grew from Bible-training schools founded to prepare its ministers.
The movement, whose members historically preferred simply to be called Christians rather than adherents of a denomination, today operates its international offices under the name Church of God Ministries, headquartered in Anderson. It reports congregations in roughly 90 countries, with a 2020 count of about 7,800 congregations and 887,000 members worldwide, though because the movement maintains no formal membership rolls, such figures are necessarily estimates rather than an audited count. It is counted among the classic denominations of the American Holiness movement, alongside bodies such as the Wesleyan Church, the Free Methodist Church, and the Church of the Nazarene, sharing their emphasis on entire sanctification while remaining doctrinally and organizationally distinct from each.
