I have given these important extracts at length because they speak for themselves. If I mistake not, they will be more convincing than many arguments. It is impossible to doubt the sincerity of Irenæus, when he thus explicitly and repeatedly maintains that the doctrines which he holds and teaches are the same which Polycarp had held and taught before him. On the other hand, a school of critics which has arisen in the present generation maintains that Irenæus was mistaken from beginning to end; that, instead of this continuity in the teaching and history of the Church, there had been a violent dislocation; that St John, as an Apostle of the Circumcision, must have had a deep-rooted aversion to the doctrine and work of St Paul; and that Polycarp, as a disciple of St John, must have shared that aversion, and cannot therefore have recognized the authority of the Apostle of the Gentiles.
It is difficult to believe that those who hold this theory have seriously faced the historical difficulties which it involves, or have attempted to realize any combination of circumstances by which this revolution could have been brought about in such a manner as to escape the notice of the next succeeding generations. I shall probably have occasion hereafter to speak of the solidarity of the Church at this epoch. At present it is sufficient to say that the direct personal testimony of Irenæus respecting Polycarp is by no means the only, or even the greatest, impediment to this theory. He constantly appeals to the Asiatic elders, the disciples and followers of the Apostles, in confirmation of his statement. Among the Christian teachers of proconsular Asia who immediately succeeded Polycarp, are two famous names, Melito of Sardis and Claudius Apollinaris of Hierapolis. They must already have reached middle life before Polycarp's martyrdom. They were not merely practical workers, but voluminous writers also. The lists of their works handed down to us comprise the widest range of topics; they handle questions of Christian ethics, of Scriptural interpretation, of controversial divinity, of ecclesiastical order, of theological metaphysics. Was there then any possibility of a mistake here? To us the history of the Church during the second century is obscure, because all this voluminous literature, except a few meagre fragments, has been blotted out. But to the contemporaries and successors of Irenæus it was legible enough. 'Who does not know,' exclaims his own pupil Hippolytus, 'the books of Irenæus and Melito and the rest, which declare Christ to be God and man?' [102:1]
