The Church of God (Anderson, Indiana) is an international holiness Christian denomination with roots in Wesleyan-Arminianism and also in the restorationist traditions. The organization grew out of the evangelistic efforts of several Holiness evangelists in Indiana and Michigan in the early 1880s, most notably Daniel Sidney Warner.
One of its more distinctive features is that there is no formal membership, since the movement believes that true salvation through Jesus Christ, the son of God, makes one a member. Similarly, there is no formal creed other than the Bible. Accordingly, there is much official room for diversity and theological dialogue, even though the movement's culture is strongly rooted in Wesleyan holiness theology.
This Wesleyan-Holiness church movement is not historically related to other Church of God bodies such as the Church of God (Cleveland, Tennessee) or the Church of God (Charleston, Tennessee). Though these bodies are also holiness Christian in outlook, the Church of God (Anderson) does not share the Pentecostal practices of the latter two denominations. Although not part of the organization's formal name, "Anderson, Indiana" is usually appended to its name to distinguish it from these other groups.
The history of the Church of God (Anderson) begins in 1881 with Daniel Sidney Warner and several others. Warner had been a member of John Winebrenner's General Eldership of the Church of God, whose members were called Winebrennerians. He differed with the Winebrennerians on the doctrine of sanctification, which he held to be a second definite work of grace, and on the nature of the church. The desire of Warner and the others was to forsake denominationalism and creeds. To this end, they determined to trust in the Holy Spirit as their guide and the Bible as their creed. Warner's vision was that the Church of God would "extend our hand in fellowship to every blood-washed one", rather than align themselves with a movement.
From its beginnings, the Church of God had a commitment to pacifism and antiracism.
