Born into Spanish nobility, Diego Luis de San Vitores was destined for an influential life. He spurned worldly power, though, to become a Jesuit missionary, writing that he felt called to “proclaim the Gospel to the poor” (Lk 4:18) — a call that led to his martyrdom.
San Vitores grew up in Burgos, Spain, where his father was a prominent official. Inspired by his Jesuit education, he wanted to become a Jesuit from a young age. His parents were strongly opposed but eventually relented, allowing him to enter the novitiate at age 12. He was ordained a priest in 1651.
Teaching and preaching for several years in Spain, Father San Vitores felt a growing desire to become a missionary. His prayers were answered in 1659, when he was sent to the Philippines. On the way, he spent 18 months in Mexico and also stopped in Guam, resolving to return and establish a mission there.
In the Philippines, Father San Vitores learned Tagalog and taught theology at Manila’s Jesuit university. A pastor at heart, he ministered to villagers while petitioning King Philip IV for permission to go to Guam. He arrived there in June 1668, bringing with him several other missionaries, including the Filipino catechist Pedro Calungsod.
They received a warm reception from Chief Kepuha of Hagåtña and began evangelizing to the Indigenous Chamorro people with significant success. Within months, however, tensions rose. Several missionaries were killed, but Father San Vitores persisted in evangelizing until April 1672, when he and Calungsod were attacked. Enraged that the priest had baptized his child, a Chamorro man and his friend killed both missionaries, dumping their bodies in the ocean.
Father Diego Luis de San Vitores was beatified in 1985; Pedro Calungsod was canonized in 2012.
