In 1948 Hieromonk Anthony (Bloom) was appointed Chaplain of the Anglican-Orthodox Fellowship of Saint Alban and Saint Sergius. On 1 September 1950 Hieromonk Anthony became the Rector of the Russian Parish of the Dormition in London. But by that time, the Parish of the Dormition was not the only Russian Orthodox parish in Great Britain, as a number of other parishes appeared, set up by Russian Orthodox communities. This prompted, in 1957, the formation in Great Britain of the Vicariate of Sergievo of the Exarchate of Western Europe (Moscow Patriarchate), with Hieromonk Anthony now becoming Bishop of Sergievo.
