United Armenian Catholic Church in the British Isles – Decree
(i) Whereas the United Armenian Catholic Church in the British Isles was founded by Mar Leon (Leon Chechemian, 1848-1920) on 15 August 1889. (ii) And whereas Mar Leon held its Primacy until his retirement in 1900, when he was succeeded by Mar Theophilus (Charles Isaac Stevens, 1835-1917), and that from 1900 until 1945 its Primacy was united with that of the Ancient British Church.
And whereas in 1945 the Primate, Mar Jacobus II, resigned his position in favour of Mar Georgius, and that at this point the United Armenian Catholic Church in the British Isles became united with the Catholic Apostolic Church (Catholicate of the West).
And whereas on the abandonment of the Catholicate of the West by Mar Georgius on 29 November 1953 the United Armenian Catholic Church in the British Isles continued to be a part of the continuing Catholicate of the West as established previously (see Decree regarding the Catholicate of the West), and remains so today.
