St. Irenaeus of Lyons, France (120-203 A.D.) - As a boy he had, as he delighted to point out, listened to the sermons of the great bishop and martyr, Polycarp of Smyrna, who was regarded as a disciple of the Apostles [John and possibly Paul] themselves -
Relatively little is known of the life of Irenaeus. As a boy he had, as he delighted to point out, listened to the sermons of the great bishop and martyr, Polycarp of Smyrna, who was regarded as a disciple of the apostles themselves. Here he came to know, 'the genuine unadulterated gospel', to which he remained faithful throughout his life. Perhaps he also accompanied Polycarp on his journey to Rome in connection with the controversy over the date of celebrating Easter (154 CE). Later he went as a missionary to southern Gaul, where he became a presbyter at Lyons. A Catholic Encyclopedia article is online at St. Irenaeus. Irenaeus was absent from the city when the persecution there reached its zenith. It seems that he had been sent to Rome by the Gallican churches in order to confer with Pope Eleutherus, perhaps as a mediator in the Montanist disputes. Evidently Irenaeus stayed in Rome for just a short time, and soon after the end of the persecution we find him again in Lyons as the successor to Bishop Pothinus (178). When and how he died is unknown to us. Jerome and others state that he died as a martyr in the persecution under the Emperor Septimus Severus (202), but there is no certainty about this tradition. In short, we know Irenaeus almost solely from his writings, and these have not been preserved in their entirety. ... The era in which Irenaeus lived was a time of expansion and inner tensions in the church. In many cases Irenaeus acted as mediator between various contending factions. The churches of Asia Minor (where he was probably born) continued to celebrate Easter on the same date (the 14th of Nisan) as the Jews celebrated Passover, whereas the Roman Church maintained that Easter should always be celebrated on a Sunday (the day of the Resurrection). Mediating between the parties, Irenaeus stated that differences in external factors, such as dates of festivals, need not be so serious as to destroy church unity. Irenaeus adopted a totally negative and unresponsive attitude, however, toward Marcion, a schismatic leader in Rome, and toward the Valentinians, a fashionable intellectual Gnostic movement in the rapidly expanding church that espoused dualism. Because Gnosticism was overcome by the Orthodox Church, Gnostic writings were largely obliterated. In reconstructing Gnostic doctrines, therefore, modern scholars relied to a great extent on the writings of Irenaeus, who summarized the Gnostic views before attacking them. After the discovery of the Gnostic library near Nag Hammadi in Egypt in the 1940s (see Robinson), respect for Irenaeus increased. He was proved to have been extremely precise in his report of the doctrines he rejected. The oldest lists of bishops also were countermeasures against the Gnostics, who said that they possessed a secret oral tradition from Jesus himself. Against such statements Irenaeus maintains that the bishops in different cities are known as far back as the Apostles - and none of them was a Gnostic - and that the bishops provided the only safe guide to the interpretation of the Scriptures. With these lists of bishops the later doctrine of "the apostolic succession" of the bishops could be linked.
