Liturgy in the diocese is primarily based around the ordinary form of the Roman Rite, promulgated by Pope Paul VI, now in its third edition. However, as might be expected from a city as cosmopolitan as London, there is a great diversity in the liturgy as celebrated by Catholics. The Latin Mass Society celebrates the liturgy according to the extraordinary form of the Roman Rite. The Ukrainian Greek Catholics have a strong presence in the diocese with their own cathedral in Binney Street close to Bond Street. There is a Lebanese Maronite community based at Our Lady of Sorrows Catholic Church in Cirencester Street in West London; a Melkite community in Pimlico, at St Barnabas' Church of England church; an Ethiopian Catholic church, Our Lady Queen of Heaven, in Queensway West London; an Eritrean Catholic church, St Aidan of Lindisfarne, in East Acton; a Chaldean Catholic church, St Anne's, in Laxton Place; and a Belarusian Catholic church in Holden Avenue in North London. There are also a large number of Masses for the expatriate Polish community; as well as French, German, Italian, Portuguese and Spanish language churches.
