During Vatican II, many changes occurred in the Catholic Church. These changes cause problem and affects the spiritual faith of the people. If we remember protestant reformation, these protestant wants to reform the Church and ignore the sacred tradition that was obtained from the previous Christian teachings including the teachings of the Apostles and the church fathers. The church called for the Council of Trent to solve this problem until the solution came under the reign of Pope St. Pius V. Return to the tradition and organize everything. These results the Tridentine Mass and the Catechism of the Catholic Church. The solution of the Council of Trent remains until the modernist called for reform, which is similar to what the Protestants wants. And it happened during the Second Vatican Council.
