About Callistus I
Callistus I served as Pope from 217-222 AD and was martyred under Emperor Alexander Severus. Before becoming pope, Callistus had a dramatic life: a slave who mismanaged funds and was sent to work in Sardinian mines, he was later freed and became a deacon under Pope Zephyrinus, who placed him in charge of the Christian cemetery on the Appian Way (now the Catacomb of Callistus). As pope, Callistus showed pastoral mercy, readmitting to communion those who had committed serious sins but truly repented—a controversial position opposed by rigorists like Hippolytus. He also recognized marriages between free women and slaves, contrary to Roman law. His merciful approach to penitents established important precedents in church discipline. Callistus was martyred, reportedly thrown into a well during a riot. The catacombs bearing his name became the burial place of many early popes.
