After Ilia II became the patriarch (catholicos) of the Georgian Orthodox Church in the late 1970s, Georgian Orthodoxy experienced a revival. In 1988, Moscow permitted the patriarch to begin consecrating and reopening closed churches, and a large-scale restoration process began. The Georgian Orthodox Church has regained much power and full independence from the state since the restoration of Georgia's independence in 1991. Georgian Orthodox and Apostolic Church The Georgian Orthodox Church (full title Georgian Apostolic Autocephalous Orthodox Church, or in the Georgian language, საქართველოს სამოციქულო მართლმადიდებელი ავტოკეფალური ეკლესია Sakartvelos Samocikulo Martlmadidebeli Avt'ok'epaluri Ek'lesia) is one of the world's oldest Christian Churches, and tradition traces its origins to the mission of Apostle Andrew in the 1st century.
