If Hippolytus reflects the spirit of Irenæus in all his writings, it is not remarkable. He was the spiritual son of the great Bishop of Lyons, and deeply imbued with the family character imparted to his disciples by the blessed presbyter of Patmos and Ephesus. But while Cyprian is the spiritual son and pupil of Tertullian, we must seek his characteristics and the key to his whole ministry in the far-off See and city where the disciples were first called Christians. Cyprian is the Ignatius of the West. We see in his works how truly historical are the writings of Ignatius, and how diffused was his simple and elementary system of organic unity. It embodies no hierarchical assumption, no "lordship over God's heritage," but is conceived in the spirit of St. Peter when he disclaimed all this, and said, "The presbyters who are among you I exhort, who am also a presbyter."
