St. Callistus I

Callistus I knew suffering before he became bishop of Rome. The early accounts speak of disgrace, punishment, and the mines before he served Pope Zephyrinus as a deacon and was later chosen pope himself.

As pope, Callistus defended the Church's power to receive repentant sinners. He resisted the harshness that would close the door of mercy to those who had fallen gravely, while holding fast to the faith entrusted to the Church.

The cemetery on the Via Appia that bears his name still recalls the Roman Christians he served. Much of the detailed story comes from Hippolytus, a hostile witness, so particular claims must be handled with care. The Church nevertheless remembers Callistus as a pope and martyr whose ministry joined truth with mercy.
