The Catholicate of the West was organised into several autocephalous patriarchates and dioceses or eparchies. The Catholicate of the West had been divided into 8
dioceses by March 1947: • Patriarchal Archdiocese of Glastonbury (counties of Somerset, Wilts, Dorset, Hants, Surrey, London, Middlesex), headed by Newman (Patriarch Mar Georgius) with his assistants (Mar Joannes,
titular bishop of St Marylebone, and Mar Benignus, titular bishop of Mere) • Diocese of Selsey (Sussex), headed by Mar Jacobus II • Diocese of Siluria (Principality of Wales and county of Monmouth), headed by Mar Hedley • Diocese of Mercia (Berks and Oxon), headed by Mar Theodorus • Diocese of Repton (counties of Derby, Stafford, Cheshire, Lancashire), headed by Mar David • Diocese of Minster (Kent and Essex), headed by Mar Francis • Diocese of Deira (County of York), headed by Mar Adrianus • Diocese of Verulam (Hertfordshire), headed by Mar John "All the rest of the
British Isles remained under the personal jurisdiction of Mar Georgius, pending the erection of more dioceses". By a
bull dated 27 July 1947, Newman "erected a small group of ex-Latin Catholics in
Belgium" into a
rite "under his own jurisdiction. This new body was given the name of ''L'Église Catholique du Rite
Dominicain''". The catholicate had also been divided, by the 12 November 1947 or by 1948, into 12
eparchies (later called "apostolikes") representing the
12 tribes of the
spiritual Israel. Those eparchies were "constituted on a general basis of the origins,
races, and
languages of
Europe and
Asia Minor in the days of the
Undivided Church. Territories since discovered were regarded as 'suburbs' of the nations mainly responsible for their development". Those eparchies were each to be led by an apostolic
primate; only three of the 12 eparchies had an apostolic primate. The 12 eparchies were the eparchies: • of all
Britons (British Isles and British overseas possessions outside of America), headed by the Patriarchate of Glastonbury • of all the
Iberians (Spain, Portugal,
Portuguese overseas possessions, Andorra and the
Americas), headed by the Patriarchate of Malaga • of all the
Frisians (Netherlands and Indonesia), headed by the Patriarchate of Amersfoort • of all the
Helvetians (Switzerland and the Principality of Lichtenchtein) • of all the
Latins (Italy,
Italian overseas possessions,
Vatican City,
San Marino) • of all the
Franks (France,
French overseas possessions, Belgium and
its overseas possessions, and the Principality of Monaco) • of all the
Teutons (Germany, and the
Free City of Danzig) • of all the
Pannonians (Austria and
Czechoslovakia) • of all the
Slavs (Russia, Poland, and the
Baltic States) • of all the
Turanians (Hungary, Finland, and Turkey) • of all the
Scandinavians (Denmark, Norway, Sweden, Iceland, and Greenland) • of all the
Levantines (Greece, Albania, the
Balkan States,
Asia Minor, and Egypt) Five
church courts of the catholicate were set up near
Kew Gardens: the Diocesan Tribunal, the Provincial Tribunal, the
Exarchal Tribunal, the Patriarchal Tribunal, and the Supreme Ecclesiastical Tribunal. == Doctrine ==
