Three things made Francis of Caracciolo stand out from his wealthy Neapolitan friends: he was powerfully drawn to our Lord in the Blessed Sacrament, he fasted every Saturday in honor of the Virgin Mary, and he had a generous love for the poor. When he was seriously ill at the age of twenty-two, he vowed that if he were cured he would devote himself to the service of God and his fellow men. He became a priest and in 1588 joined the order of Minor Clerks Regular. Francis instituted perpetual adoration as one of the works of his Order. According to the 1962 Missal of St. John XXIII the Extraordinary Form of the Roman Rite, today is his feast.
