Between the death of St. John and the mature lifetime of St. Irenæus fifty years elapsed. St. Polycarp was disciple of St. John. St. Irenæus was disciple of St. Polycarp. The mind of St. John and the mind of St. Irenæus had only one intermediate intelligence, in contact with each. It would be an affectation of minute criticism to treat the doctrine of St. Irenaeus as a departure from the doctrine of St. Polycarp, or the doctrine of St. Polycarp as a departure from the doctrine of St. John. Moreover, St. John ruled the Church at Ephesus, and St. Irenaeus was born in Asia Minor about the year A. D. 120--that is, twenty years after St. John's death, when the Church in Asia Minor was still full of the light of his teaching and of the accents of his voice. Let us see how St. Irenæus describes the faith and the Church. In his work against Heresies, in Book iii. chap. i., he says, "We have known the way of our salvation by those through whom the Gospel came to us; which, indeed, they then preached, but afterwards, by the will of God, delivered to us in Scriptures, the future foundation and pillar of our faith. It is not lawful to say that they preached before they had perfect knowledge, as some dare to affirm, boasting themselves to be correctors of the Apostles. For after our Lord rose from the dead, and when they had been clothed with the power of the Holy Ghost, Who came upon them from on high, they were filled with all truths, and had knowledge which was perfect." In chapter ii. he adds that, "When they are refuted out of Scripture, they turn and accuse the Scriptures as erroneous, unauthoritative, and of various readings, so that the truth cannot be found by those who do not know tradition"--that is, their own. "But when we challenge them to come to the tradition of the Apostles, which is in custody of the succession of Presbyters in the Church, they turn against tradition, saying that they are not only wiser than the Presbyters, but even the Apostles, and have found the truth." "It therefore comes to pass that they will not agree either with the Scriptures or with tradition." (Ibid. c. iii.) "Therefore, all who desire to know the truth ought to look to the tradition of the Apostles, which is manifest in all the world and in all the Church. We are able to count up the Bishops who were instituted in the Church by the Apostles, and their successors to our day. They never taught nor knew such things as these men madly assert." "But as it would be too long in such a book as this to enumerate the successions of all the Churches, we point to the tradition of the greatest, most ancient Church, known to all, founded and constituted in Rome by the two glorious Apostles Peter and Paul, and to the faith announced to all men, coming down to us by the succession of Bishops, thereby confounding all those who, in any way, by self-pleasing, or vainglory, or blindness, or an evil mind, teach as they ought not. For with this Church, by reason of its greater
