_Irenaeus_ of Lyons is the next writer who claims our special notice. He was originally connected with Asia Minor; and in his youth he is said to have enjoyed the tuition of Polycarp of Smyrna. We cannot tell when he left his native country, or what circumstances led him to settle on the banks of the Rhone; but we know that, towards the termination of the reign of Marcus Aurelius, he was appointed by the Gallic Christians to visit the Roman Church on a mission of importance. The Celtic language, still preserved in the Gaelic or Irish, was then spoken in France, [368:4] and Irenaeus found it necessary to qualify himself for the duties of a preacher among the heathen by studying the barbarous dialect. His zeal, energy, and talent were duly appreciated; soon after the death of the aged Pothinus he became the chief pastor of Lyons; and for many years he exercised considerable influence throughout the whole of the Western Church. When the Paschal controversy created such excitement, and when Victor of Rome threatened to rend the Christian commonwealth by his impetuous and haughty bearing, Irenaeus interposed, and to some extent succeeded in moderating the violence of the Italian prelate. He was the author of several works, [369:1] but his only extant production is a treatise "Against Heresies." It is divided into five books, four of which exist only in a Latin version; [369:2] and it contains a lengthened refutation of the Valentinians and other Gnostics. Irenaeus is commonly called the disciple of Polycarp; but it is reported that he was also under the tuition of a less intelligent preceptor, Papias of Hierapolis. [369:3] This teacher, who has been already mentioned, and who was the author of a work now lost, entitled, "The Explanations of the Discourses of the Lord," is noted as the earliest ecclesiastical writer who held the doctrine of the personal reign of Christ at Jerusalem during the millennium. "These views," says Eusebius, "he appears to have adopted in consequence of having misunderstood the apostolic narratives.... For he was a man of very slender intellect, as is evident from his discourses." [369:4] His pupil Irenaeus possessed a much superior capacity; but even his writings are not destitute of puerilities; and it is not improbable that he derived some of the errors to be found in them from his weak-minded teacher.
