β Biography
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 Christβs person. During his papacy, Felix I confronted the heresy of Paul of Samosata, who denied the divinity of Christ. 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.
