St. Francis Xavier was a Jesuit missionary who carried the Gospel to India and Japan.
The goal of the Jesuit missionaries, or the Society of Jesus, was to go anywhere in the world to serve the church.
Francis was sent to India because the Portuguese settlers there were loosing their faith and Christian values.
Francis started to minister the people of Pearl Fishery Coast because most of them had been baptized, but were never taught faith. He spent three years among them, and built 40 churches for them.
After India, Francis eventually decided to travel to Malacca and the Maluku Islands in Japan to evangelize there.
The Japanese were not easily converted, most held onto their traditional Buddhist or Shinto beliefs.
