Saint Callistus I

October 14.—ST. CALLISTUS, Pope, Martyr.
EARLY in the third century, Callistus, then a deacon, was entrusted by Pope St. Zephyrinus with the rule of the clergy, and set by him over the cemeteries of the Christians at Rome; and, at the death of Zephyrinus, Callistus, according to the Roman usage, succeeded to the Apostolic See. A decree is ascribed to him appointing the four fasts of the Ember seasons, but his name is best known in connection with the old cemetery on the Appian Way, which was enlarged and adorned by him, and is called to this day the Catacomb of St. Callistus. During the persecution under the Emperor Severus, St. Callistus was driven to take shelter in the poor and populous quarters of the city; yet, in spite of these troubles, and of the care of the Church, he made diligent search for the body of Calipodius, one of his clergy who had suffered martyrdom shortly before, by being cast into the Tiber. When he found it he was full of joy, and buried it, with hymns of praise. Callistus was martyred October 14, 223.
Reflection.—In the body of a Christian we see that which has been the temple of the Holy Ghost, which even now is precious in the eyes of God, Who will watch over it, and one day raise it up in glory to shine forever in His kingdom. Let our actions bear witness to our belief in these truths.
Saint Callistus I, Pope and Martyr] Eph 1:11-14/Lk 12:1-7 (471).

CATHOLICISM SAINTS ST. CALLISTUS I
Pope Callixtus I, 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 gave him five years of episcopate (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 martyred for his Christian faith and is venerated as a saint by the Catholic Church (the patron saint of cemetery workers).

I will listen to what God the Lord says; he promises peace to his people, his faithful servants – but let them not turn to folly. Surely his salvation is near those who fear him, that his glory may dwell in our land.
Ps 85:8–9
