Pope Callistus I is celebrated in churches throughout the world as a saint and martyr on October 14. The saint caused a major controversy, including a schism that lasted almost two decades, by choosing to emphasize God's mercy in his ministry. However, the early Pope's model of leadership has endured, and his martyrdom in the year 222 confirmed his example of holiness.
Because no completely trustworthy biography of Pope Callistus I exists, historians have been forced to rely on an account by his contemporary Hippolytus of Rome. Although Hippolytus himself was eventually reconciled to the Church and canonized as a martyr, he vocally opposed the pontificate of Callistus and three of his successors, to the point of usurping papal prerogatives for himself (as the first “antipope”). Nevertheless, his account of Callistus' life and papacy provides important details.
According to Hippolytus' account, Callistus – whose year of birth is not known - began his career as a highly-placed domestic servant, eventually taking responsibility for his master's banking business. When the bank failed, Callistus received the blame, and attempted to flee from his master. Being discovered, he was demoted to serve as a manual laborer in Rome. Thus, under inauspicious circumstances, Callistus came as a slave to the city where he would later serve as Pope.
Matters went from bad to worse when he was sent to work in the mines, possibly for causing a public disturbance, if Hippolytus' account is to be trusted. However, Callistus may also simply have been sentenced due to a persecution of Christians, as he was among the many believers eventually freed on the initiative of Pope St. Victor I.
During the subsequent reign of Pope Zephyrinus, Callistus became a deacon and the caretaker of a major Roman Christian cemetery (which still bears his name as the “Cemetery of St. Callistus”), in addition to advising the Pope on theological controversies of the day. He was a natural candidate to follow Zephyrinus, when the latter died in 219.
