The '''Antiochian Orthodox Christian Archdiocese of the British Isles and Ireland''' is an archdiocese of the [[Church of Antioch]]. It was created by the Holy Synod of Antioch, led by Patriarch [[John X (Yazigi) of Antioch|John]], on 17 October 2013. It is currently led by Archpriest Gregory Hallam, awaiting the appointment of a Patriarchal Vicar Bishop.

The Archdiocese has a cathedral, 14 16 parishes and 7 5 mission communities - a list of these can be found [httphttps://www.antiochian-orthodox.co.ukcom/Parishes/parishes.htm parish-directory on the Archdiocesan website]. These are served by a resident Archbishop, Metropolitan Silouan Oner, 26 priests, 5 deacons and 2 retired priests. Though most communities initially consisted largely of converts from the Church of England, this had changed significantly by 2000 for a much more diverse congregations. All communities of the Archdiocese use English as the liturgical languageexcept the Cathedral Community of St George. The mission of the Archdiocese is to enable the indigenous cultures to rediscover and reaffirm their Orthodox roots whilst at the same time integrating Orthodox of many other backgrounds in a unified ecclesial whole, the hallmark of catholicity.
