Opus Dei is Latin for “God’s work”. It was founded by St Josemaria Escriva in 1928 and its purpose is to tell everyone that God wants them to be really good, in fact saints! And to be so in their daily lives, at work, with their family, friends, whatever they are doing. Opus Dei also teaches those who want to put this into practice, how to do so. For this purpose it was established as a personal Prelature of the Catholic Church, by Pope John Paul II in 1982. Opus Dei has some 84,000 members worldwide in more than fifty countries. In Britain it has centres in London, Glasgow, Manchester and Oxford, including Netherhall House in north London, Grandpont House in Oxford, Dunreath in Glasgow, Kelston in south London, and Greygarth Hall in Manchester.
