June 28 – Irenaeus
Irenaeus (125?-202) was an early Church father, having been taught by Polycarp, who had been taught by John the Evangelist.
During the persecution of Marcus Aurelius, the Roman Emperor from 161-180 the clergy of that city, many of whom were suffering imprisonment for the faith, sent him in 177 to Rome with a letter to Pope Eleuterus concerning heresy. While Irenaeus was in Rome, a massacre took place in Lyons. Returning to Gaul, Irenaeus succeeded the martyr Saint Pothinus and became the second Bishop of Lyon, the main trading port for Western Gaul (France). During the religious peace which followed the persecution of Marcus Aurelius, the new bishop divided his activities between the duties of a pastor and of a missionary.
We remember him for two things – his work against Gnosticism and the recognition of the four gospels. He apparently did well there, becoming an influential leader against the rising heterodoxy Gnosticism. He first used the word to describe heresies . The Gnostics saw the world as material, and leaves much room for improvement and they denied that God had made it. They saw Jesus more as a spirit than a real flesh human . Before Irenaeus, Christians differed as to which gospel they preferred. Irenaeus is the earliest witness to recognize the four authentic gospels, the same we have today. Irenaeus is also our earliest attestation that the Gospel of John was written by John the apostle and that the Gospel of Luke was written by Luke, the companion of Paul.
