The ordinariate, established in 2011, has about 90 clergy serving 50 ordinariate groups across Britain. About 20 of its priests run diocesan parishes, but the demands of parish life can leave little time to maintain a distinctive ordinariate identity.
Very few of these churches have a formal arrangement that allows a focus on the ordinariate mission. Exceptions include the Church of Our Lady of the Assumption and St Gregory, Soho, London, and the Church of the Most Precious Blood in Borough, Lonodn.
The structure was established by Benedict XVI to allow groups of former Anglicans to seek full communion with the Catholic Church while maintaining elements of their liturgical traditions.
