According to the 1962 Missal of St. John XXIII the Extraordinary Form of the Roman Rite, today is the feast of St. Felix who lived in the third century. He was a priest and suffered greatly in the Decian persecution. The tomb of St. Felix at Nola, a small town in the south of Italy, was a much frequented place of pilgrimage in Christian antiquity, and in the Middle Ages veneration of him spread throughout the west. Along with St. Hilary his feast is celebrated today on the Extraordinary Form Calendar. St. Hilary’s feast is celebrated on January 13 in the Ordinary Form Calendar.
