When in 1564 Augustinians were being chosen to accompany
Andrés de Urdaneta, OSA, on the royal expedition to the Philippines that was to sail from Mexico under the command of Don
Miguel López de Legazpi, his
Father Provincial (or regional religious superior) in Spain asked that de Rada should stay in Mexico "until it is known about the success of the armada" (that is, the success of Legazpi's armed fleet in its attempt to reach and colonize the Philippines). As it happened, de Rada had already sailed in the Legazpi expedition before the Provincial's letter reached Mexico. The Legazpi expedition reached
Cebu in the Philippines on April 27, 1565. When on June 1, 1565, Urdaneta, accompanied by
Andrés de Aguirre, OSA, began his historic return voyage of exploration to Mexico, de Rada remained in the Philippines with Diego de Herrera, OSA, and Pedro de Gamboa, OSA. The trio quickly learned the local
Cebuano language. De Rada remained at Cebu from 1565 to 1572, earning him a place in history as "the apostle of the Christian Faith in Cebu." In 1566-67, he also made voyages to adjacent islands, mainly
Panay, and preached there as well. In 1572 he became the Augustinian regional superior in the Philippines. While in Cebu, de Rada had begun to study
Chinese. In 1574, he acted as an interpreter to a group of Chinese merchants who visited
Manila. He later proposed a plan to
conquer China that was never realized. is one of the grand bridges that de Rada's delegation used on its way from Amoy to Fuzhou. On June 26, 1575, de Rada and
Jeronimo Marin, OSA, accompanied a delegation of officials to
China. They reached the port of
Amoy (Xiamen) in
Hokkien province on July 5, and visited a number of cities. The group returned to Manila on October 28, 1575. De Rada wrote detailed observations on the Chinese people and their way of life. In 1578 de Rada was once again placed on an expedition by the governor of Manila; this was to
Borneo, where there was rivalry within the family of the
sultan. The expedition sailed from Manila on March 3, 1578, but was not successful. On the return voyage many people in the expedition got sick. De Rada was one of those less fortunate, and died at sea on the 12th of June shortly before the ship reached Manila. He was only forty-five years of age. ==Legacies==
