Although for several centuries the Roman Catholic Church was the only legal religion in Latin America, its popular support was neither wide nor deep.5 Many huge rural areas were without churches or priests, a vacuum in which indigenous faiths persisted.6 Even in the large cities with their splendid cathedrals, mass attendance was very low - as recently as the 1950s perhaps only 10 to, at most, 20 per cent of Latin Americans were active participants in the faith.7 Reflective of the superficiality of Latin Catholicism, so few men entered the priesthood that all across the continent most of the priests had always been imported from abroad.
