Much at stake for Opus Dei in conclave
Founded in Spain in 1928, the movement has more than 80,000 members worldwide, many of them lay people but also hundreds of priests, bishops and even two cardinals who will be casting votes in Rome.
Its mission - to give lay people a dynamic role in spreading the word of God - enjoyed firm support from John Paul II, who championed the movement as a means of confronting the secularisation of society and reinforcing his conservative doctrine.
