Sister Anita Caspary of California led her fellow sisters of the Order of the Immaculate Heart of Mary in a move for change. They dropped their habits and veils - and started an almighty row which ended in their leaving the Roman Catholic Church. Father Charles Davis became a Catholic cause celebre when he left his vocation and married. In Holland other priests are doing the same. The row about birth control, about the Latin Mass, and the problem of shrinking congregations and dwindling numbers in the priesthood splits the Catholic Church with debate: a debate concerned with the role of Catholicism in the 20th century, the position of the Pope, and the authority of the Vatican.
