The Church of God of the Mountain Assembly, Inc. (CGMA) is a holiness pentecostal Christian body formed in 1907, with roots in the late 19th century American holiness movement and early 20th century Pentecostal revival. The denomination maintains headquarters in Jellico, Tennessee and is a member of the Pentecostal/Charismatic Churches of North America (formerly the Pentecostal Fellowship of North America) and a member of the National Association of Evangelicals.
Around 1902 several ministers of the South Union Association of United Baptists became involved in the holiness movement. At their annual session in 1903, the South Union Association excluded all ministers preaching apostasy (the possibility of losing one's salvation). On August 24, 1907, representatives met at the Jellico Creek church in Whitley County, Kentucky and formed a new association. They chose the name Church of God. The early leaders were ministers J. H. Parks, Steve Bryant, and Tom Moses. Shortly after organization, they accepted the Pentecostal revival. After discovering that other bodies were holding property and transacting business under the name Church of God, this body added the words "of the Mountain Assembly" to "Church of God" for identification and legal purposes in 1911. In 1917 the body was incorporated, and in 1922 headquarters were established in Jellico, Tennessee.
The Church of God Mountain Assembly has suffered three divisions since its formation, resulting in the existence of the Church of God General Assembly (org. 1914 in McCreary County, Kentucky), Church of God of the Union Assembly (org. 1920 in Jackson County, Georgia) and the Church of God of the Original Mountain Assembly (org. 1946 at Williamsburg, Kentucky).
The church has drawn up a Church Covenant, and holds a twelve article Statement of Faith. Doctrines of the Church of God Mountain Assembly include:
They have a 38 acre (154,000 m²) youth campground near Winchester, Ohio, with a large tabernacle, a cafeteria, offices, many dormitories and cabins. Also the world headquarters office is in Jellico, Tennessee.
Their annual Campmeeting convention is the first week of August in Gatlinburg, TN, and their annual Florida Campmeeting is the last week of January in Kissimmee, Florida.
