The Pentecostal Church of Go (PCG) is a trinitarian Pentecostal Christian denomination. It was formed in Chicago, Illinois, in 1919, by a group of Pentecostal ministers who had chosen not to affiliate with the Assemblies of God (org. 1914). It was first called the Pentecostal Assemblies of America, then Pentecostal Church of God of America was adopted in 1922, and the present name was formed by dropping "of America" in 1979. John C. Sinclair served as the first moderator. The Pentecostal Church of God should not be confused with the The Pentecostal Church of God (Detroit), which is a non-trinitarian Pentecostal denomination based in Detroit, Michigan.
