Feast day: June 12
Saint John of Sahagun was a priest, spiritual advisor, scholar, and preacher. He became an Augustinian friar and had prayerful visions, performed miracles, and had the gift of reading souls. He publicly denounced evil actions, which angered some townsfolk who did not want to change their sinful ways. Several attempts were made on his life, and it is said that he was eventually poisoned by the enraged mistress of a prominent man who had stopped seeing her on the advice of John.
