The Celtic Orthodox Church is one of the Ancient Christian Churches. Founded in AD37, it radiated across Europe, remaining faithful to its tradition and its spirituality during the first twelve centuries of the Christian era. It is the original Church of Great Britain.
In 2007 the Celtic Orthodox Church, the French Orthodox Church, and the Orthodox Church of the Gauls, represented by His Beatitude Metropolitan Mael de Brescia and Bishop Marc Scheerens of the Celtic Orthodox Church, Bishop Vigile and Bishop Martin Laplaud of the French Orthodox Church, and Bishop Gregoire Mendez of the Orthodox Church of the Gauls formed the Communion of the Western Orthodox Churches. The Communion has parishes, monasteries and missions across France, where the Communion was established, and in Belgium, Switzerland, the United Kingdom, Cameroon, Australia, the United States of America, Brazil, and Martinique.
The position of the Celtic Orthodox Church with regard to the Ecumenical Councils might best be described as Pro-Chalcedonian. That is to say, it accepts the teaching of all seven Councils, but acknowledges that only the first three were truly Ecumenical. Although having its apostolic roots in the Oriental (Non-Chalcedonian) Church, the Celtic Orthodox Church was given the mandate to establish a Western Orthodox Church faithful to the spirit of the original Celtic Church. It is an autocephalous Church and has never been required to be subject to the Syriac Orthodox Church, or tied to its doctrinal position. The Celtic Orthodox is not monosyphite, but upholds the doctrine that the one Person of Christ has two Natures.
The Celtic Saints have left us a rich heritage of deeply spiritual prayer, and a visionary way of finding God in the beauty of His creation. Celtic spirituality is full of symbolism, some of which was borrowed from their Druid forefathers, but given a deeper Christian significance.
