The Orthodox Church in America (OCA) is an autocephalous Orthodox Christian church in the United States. Established in 1970, it is part of the larger Eastern Orthodox Church and traces its roots to the arrival of Russian Orthodox missionaries in the 18th century. The OCA serves a diverse community, including descendants of immigrants from various Orthodox traditions. The OCA is governed by a synod of bishops and emphasizes the importance of liturgical worship and community life. It operates numerous parishes, educational institutions, and charitable organizations, promoting spiritual growth and outreach within American society.
