Felix I

Pope Felix I (died 30 December 274) was the bishop of Rome from 5 January 269 to his death on 30 December 274. Born in Rome, he succeeded Pope Dionysius and is noted for his theological contributions, particularly a significant dogmatic letter addressing the unity of Christ’s person. During his papacy, Felix I confronted the heresy of Paul of Samosata, who denied the divinity of Christ. The intervention of Emperor Aurelian, prompted by Felix, led to Paul’s deposition from the bishopric of Antioch, reinforcing orthodox Christological doctrine.

Felix is traditionally credited with instituting the practice of celebrating Mass over the tombs of martyrs, though this attribution remains a subject of historical debate. Upon his death, Felix was interred in the Catacomb of Callixtus on the Appian Way. While later accounts mistakenly honored him as a martyr, contemporary scholarship suggests he died of natural causes.
