The Church of God is an international Holiness-Pentecostal Christian denomination with headquarters in Cleveland, Tennessee, United States). It was founded in 1886 upon the principles of Christ as they are revealed in the Bible, the Word of God. The Church of God is a determinedly Christian church, built upon the person of Jesus Christ, the Son of God, and the doctrines and practices of the church are based upon His teachings. The Church of God is also founded upon the principles of Protestantism, although it is not a traditional follower of any specific leader of the Protestant Reformation. The denomination stands firmly for justification by faith, the priesthood of believers, the authority of the Bible, religious freedom, and the separation of church and state. The Church of God is affiliated with both the Pentecostal and Holiness movements and defines itself as Pentecostal. It believes that the Holy Spirit baptizes believers at specific times and locations, and Church of God members practice speaking in tongues.
