George Alexander McGuire (28 March 1866 – 10 November 1934) is best known for his prominence in Marcus Garvey's Universal Negro Improvement Association (UNIA).
McGuire was elected in 1920 as Chaplain-General of the UNIA and wrote important documents about black ritual and catechism, drawing from his knowledge of religion and African history.
Both he and Garvey were immigrants to the United States from Caribbean islands who had a vision of Pan-African goals.
In addition McGuire was known for his other religious contributions.
Already a minister in the Moravian Church when he immigrated in 1894 to the US, McGuire soon joined the Episcopal Church.
He was ordained in 1897 as an Episcopal priest.
An early member of the American Negro Historical Society in Philadelphia, McGuire became more concerned about developing institutions that supported persons of African ancestry.
In 1921 McGuire founded the African Orthodox Church (AOC); and he was consecrated that year as its first bishop, serving until his death in 1934.
During his tenure, new congregations were started in several cities in the US, Canada, the Caribbean, and in East Africa.
McGuire envisioned the AOC as a home for Blacks of Episcopal belief who wanted ecclesiastical independence.
It was based on Christian tradition and Apostolic succession.
Orthodoxy attracted persons of African descent because it had not been implicated in colonialism or slavery.
