Opus Dei
In 1982, Pope John Paul II decided to make Opus Dei into a personal prelature.  Usually, in the Catholic Church, there are separate dioceses in different areas.  Each area has its own bishop who is in charge of just that diocese.  But because Opus Dei is a personal prelature, its bishopm called the Prelate, is not limited to any specific area.  He is in charge of members of Opus Dei wherever they are, around the world. The prelate of Opus Dei is Monsignor Fernando Ocáriz Braña.
