16th century. American period: 1898–1946 When the Spanish clergy were driven out in 1898, there were so few indigenous clergy that the Catholic Church in the Philippines was in imminent danger of complete ruin. Under American administration, the situation was saved and the proper training of Filipino clergy was undertaken. In 1906, Jorge Barlin was consecrated as the Bishop of Nueva Caceres, making him the first Filipino bishop of the Catholic Church. During the sovereignty of the United States, the American government implemented the separation of church and state, which reduced the significant political power exerted by the Church, which led to the establishment of other faiths (particularly Protestantism) within the country. A provision of the 1935 Philippine Constitution mimicked the First Amendment to the United States Constitution and added the sentences: "The exercise and enjoyment of religious profession and worship, without discrimination or preference, shall be forever allowed. No religious test shall be required for the exercise of civil political rights." But the Philippine experience has shown that this theoretical wall of separation has been crossed several times by secular authorities. It was during the American Period when newer religious orders arrived in the Philippines. The Spanish friars gradually fled by the hundreds and left parishes without pastors. This prompted bishops to ask for non-Spanish Religious Congregations to set up foundations in the Philippines and help augment the lack of pastors. The American Jesuits and other religious orders from their American province filled the void left by their Spanish counterparts, creating a counterbalance to the growth of Protestant congregations by American Protestant missionaries. 1946–present After the war, most of the religious orders resumed their ecclesiastical duties and helped in the rehabilitation of towns and cities ravaged by war. Classes in Catholic schools run by religious orders resumed, with American priests specializing in academic and scientific fields fulfilling faculty roles until the mid-1970s. American and foreign bishops were gradually succeeded by Filipino bishops by the 1970s. When the Philippines was placed under Martial Law by dictator Ferdinand Marcos, relations between Church and State changed dramatically, as some bishops expressly and openly opposed Martial Law. The turning point came in 1986 when the CBCP President then-Archbishop of Cebu Ricardo Cardinal Vidal appealed to the Filipinos and the bishops against the government and the fraudulent result of the snap election; with him was then-Archbishop of Manila Jaimé Cardinal Sin, who broadcast over
