Blessed Diego Luis de San Vitores (1627-1672) was a Spanish Jesuit missionary who founded the first Catholic church on the island of Guam. His parents attempted to persuade him to pursue a military career, but he instead chose to pursue his religious interests.

He didn’t carry any arms and refused to let his companions carry arms. He was martyred.
