Genuine Orthodox Church of America
The Genuine Orthodox Church of America (GOCA) is an independent Old Calendarist jurisdiction based in Buena Vista, Colorado which sees itself as the only legitimate Orthodox church in America. They are in Communion with the Synod of Archbishop Makarios of Athens, who heads the true Orthodox Church of Greece. This can be seen by their links page on their website. It is not in communion with any other body. It is headed by Abp. Gregory (George) of Denver.
It was formed out of a group originally under the Russian Orthodox Church Outside Russia, which later joined one of the Greek Old Calendarist jurisdictions (1995), followed by the Russian Orthodox Autonomous Church (ROAC) (2000), and is now independent following the ROAC's deposition and excommunication of Abp. Gregory (2004). With its history of being a part of various jurisdictions, the Genuine Orthodox Church of America tends to be in a constant state of hostility toward its former affiliations.
The jurisdiction's bishop, Gregory (George) of Denver (born an Antiochian), who was consecrated to the episcopacy in the ROAC, claims to be "the only hierarch in the United States who has remained free of any communion or union with this heresy of Ecumenism who has valid apostolic succession," and thus claims "to be truly canonical."
