The African Orthodox Church is a primarily African-American denomination founded in the United States in 1921. It has approximately 15 parishes and 5,000 members, down significantly from its peak membership.
The AOC holds to the historic three-fold ministry of bishops, priests, and deacons, and lays strong emphasis on apostolic succession. The church celebrates the seven sacraments of the Roman Catholic Church. Its worship is liturgical, of Eastern and Western rites. The Nicene, Apostles', and Athanasian creeds are affirmed.
The African Orthodox Church (AOC) was founded in the belief that black Episcopalians should have a denomination of their own. Episcopal rector George Alexander McGuire was consecrated a bishop on September 28, 1921, in Chicago, Illinois, by Archbishop (episcopus vagans) Joseph Rene Vilatte, assisted by Bishop Carl A. Nybladh who had been consecrated by Vilatte. This placed Bishop McGuire in apostolic succession, which was something he had greatly desired.
The new denomination was originally called the Independent Episcopal Church, but at its first conclave, or House of Bishops meeting, on September 10, 1924, the denomination was formally organized as the African Orthodox Church. Bishop McGuire was unanimously elected archbishop and enthroned with the title of "Archbishop Alexander".
McGuire served for several years as chaplain of the Universal Negro Improvement Association and African Communities League (UNIA), founded and led by Marcus Garvey. When Garvey decided in 1924 to relocate UNIA headquarters to the West Indies, McGuire left the UNIA and began to devote himself to the development and extension of his church. Soon Endich Theological Seminary was founded, as well as an order of deaconesses, and the Negro Churchman magazine began publication with McGuire as its editor.
