Optional Memorial of Saint Callistus I, Pope and Martyr
Pope Callixtus I (Greek: Κάλλιστος), also called Callistus I, was the bishop of Rome (according to Sextus Julius Africanus) from c. 218 to his death c. 222 or 223. He lived during the reigns of the Roman emperors Elagabalus and Alexander Severus. Eusebius and the Liberian catalogue list his episcopate as having lasted five years (217–222). In 217, when Callixtus followed Zephyrinus as Bishop of Rome, he started to admit into the Church converts from sects or schisms. He was killed for being Christian and is venerated as a saint by the Catholic Church (the patron saint of cemetery workers).
