Pope Callixtus I
Pope Callixtus I (died circa 223), also called Callistus I, was the bishop of Rome (according to Sextus Julius Africanus) from c. 218 to his death c. 223. He lived during the reigns of the Roman Emperors Elagabalus and Alexander Severus. Eusebius and the Liberian catalogue gave him five years of episcopate (217-222). He was martyred for his Christian faith and is venerated as a saint by the Catholic Church.
Life
His contemporaries and enemies, Tertullian and Hippolytus of Rome the author of Philosophumena, relate that Callixtus, as a young slave from Rome, was put in charge of collected funds by his master Carpophorus, funds which were given as alms by other Christians for the care of widows and orphans; Callixtus lost the funds and fled from the city, but was caught near Portus. According to the tale, Callixtus jumped overboard to avoid capture but was rescued and taken back to his master. He was released at the request of the creditors, who hoped he might be able to recover some of the money, but was rearrested for fighting in a synagogue when he tried to borrow money or collect debts from some Jews.
