Biography

Who was Ignatius of Antioch?

Why this Father matters to Catholic apologetics: Ignatius had no time for speculative theology — he was writing urgent pastoral letters on the way to his death. When he states the Eucharist is the flesh of Christ, or that nothing in the Church may be done without the bishop, he is stating what he takes to be obvious. What a man states as obvious on his way to be eaten by lions is reliable testimony.

Historical Period
Apostolic

Ignatius was the third Bishop of Antioch, succeeding Evodius who had been appointed by Peter. Christian tradition holds he knew the Apostle John personally. Around AD 107, during Trajan’s reign, he was arrested and transported to Rome to be thrown to the beasts. During his journey across Asia Minor he wrote seven letters — to Ephesus, Magnesia, Tralles, Rome, Philadelphia, Smyrna, and to Polycarp personally. These letters contain the first use of the phrase “Catholic Church,” the clearest early statement of the Real Presence, and the fullest early account of episcopacy as divinely instituted.
