Cuba has a multitude of faiths reflecting the island's diverse cultural elements. Catholicism, which was brought to the island by Spanish colonialists at the beginning of the 16th century, is the most prevalent professed faith. After the revolution, Cuba became an officially atheistic state and restricted religious practice. Since the Fourth Cuban Communist Party Congress in 1991, restrictions have been eased and, according to the National Catholic Observer, direct challenges by state institutions to the right to religion have all but disappeared, though the church still faces restrictions of written and electronic communication, and can only accept donations from state-approved funding sources. The Roman Catholic Church is made up of the Cuban Catholic Bishops' Conference (COCC), led by Jaime Lucas Ortega y Alamino, Cardinal Archbishop of Havana. It has eleven dioceses, 56 orders of nuns and 24 orders of priests. In January 1998, Pope John Paul II paid a historic visit to the island, invited by the Cuban government and Catholic Church.
