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. It is not in communion with any mainstream Orthodox body, but it claims to maintain communion with the Genuine Orthodox Church of Greece, headed by Abp. Makarios of Athens. (This is officially denied by members of the Makarian Synod.) The GOAC is headed by Abp. Gregory (George) of Denver.
The GOAC 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."
