In consultation with the other orders it was decided that the Dominicans should be given the ministry of the territories of Pangasinan and Bataan, which had theretofore been spiritually exploited by few priests. Almost immediately, on September 15, 1587, the vicariate of Bataan was founded and settled. In speaking of it, Aduarte stressed the importance of a knowledge of the language of the natives, which there would have been Tagalog, to the success of the mission. Domingo de Nieva, one of the four members of the mission, learned it rapidly and well, and soon began to preach to the Indians in their own tongue. His aptitude for languages and its usefulness to the Dominicans must have been very great, for Aduarte in listing the priests who originally volunteered in Spain makes few comments about individuals, but of Nieva he remarks that he "was afterwards of great importance because of the great ease and skill with which he learned languages, whether Indian or Chinese." [99] Unfortunately Nieva was only a deacon, and so could not hear confession, a fact which was greatly deplored, because during that first year no other priest mastered the language sufficiently well to do it, but in September 1588 he reached the requisite age and was ordained. About that time the friars in Bataan--one had died and another was ailing--were joined by Juan de la Cruz, "who, being young, succeeded very well with the language," [100] and also succeeded in surviving the climate. Early in 1588 Juan Cobo [101] arrived from Mexico. Shortly thereafter, on June 12, 1588, the Dominican chapter held its first convocation. It elected Juan de Castro the first provincial, adopted the general ordinances [102] already made in Mexico, gave the convent at Manila the title of priory, and designated as parts of the province four vicariates. Of primary importance was the appointment then of Juan Cobo to the mission for the Chinese. From the very earliest days of the Spanish occupation of Manila, the governors had had trouble with the Chinese and Sangleys. [103] These people had long conducted a profitable trade between China and the Philippines, and many had settled permanently near Manila, while others stayed there regularly between trading voyages. The Chinese merchants were in full control of the shops of the city, and so monopolized retail trade that the early governors legislated [104] against them to give the Spaniards a chance to establish themselves in business. In 1588 there were as many as seven thousand of them in and around Manila.
