The Roman Catholic Church is the largest Christian group and traces its origin to Jesus' apostle, Peter, as the first Bishop of Rome. The pope as Peter's successor, is the leader and final authority in the church.  The Catholic Church has congregations called parishes in many countries of the world which are organized into dioceses.
