The Antiochian Catholic Church in America or the ACCA, is one of the Independent Catholic Churches. The ACCA is distinct from most such Churches in that it largely embraces the theology and much of the practice of the Syriac Orthodox Church and that of its daughter Church, the Indian Orthodox Church, from which the ACCA primarily derives its apostolic succession via the lineage of J.
