The great work of Irenæus is entitled Refutation and Overthrow of Knowledge falsely so called, and consists of five books. The third book was published during the episcopate of Eleutherus, who was Bishop of Rome from about A.D. 175 to A.D. 190; for he is mentioned in it as still living [260:1]. It must therefore have been written before A.D. 190. On the other hand it contains a mention of Theodotion's version of the LXX [260:2]; and Theodotion's version is stated not to have been published till the reign of Commodus (A.D. 182-190). Unfortunately Epiphanius, the authority mainly relied on by our author and others for this statement, contradicts himself in this same passage, which is full of the grossest chronological and historical blunders [260:3]. No stress therefore can be laid on his statement; nor indeed can we regard its truth or falsehood as of any real moment for our purpose. It is immaterial whether the third book dates from the earlier or later years of Eleutherus. As the several books were composed and published separately, the author of Supernatural Religion has a right to suppose, though he cannot prove, that the fourth and fifth were written during the episcopate of Victor (A.D. 190-198 or 199). But in his partiality for late dates he forgets that the weapon which he wields is double-edged. If the fourth and fifth books 'must,' as he confidently asserts, have been written some years after the third, it follows by parity of reasoning, that the first and second must have been written some years before it. Yet, with a strange inconsistency, he assumes in the very same sentence that the two first books cannot have been written till the latest years of Eleutherus, because on his showing the third must date from that epoch [261:1].

With the respective dates of the several books however we need not concern ourselves; for they all exhibit the same phenomena, so far as regards the attitude of the author towards the Canonical writings of the New Testament. On this point, it is sufficient to say that the authority which Irenæus attributes to the four Gospels, the Acts of the Apostles, the Epistles of St Paul, several of the Catholic Epistles, and the Apocalypse, falls short in no respect of the estimate of the Church Catholic in the fourth or the ninth or the nineteenth century. He treats them as on a level with the Canonical books of the Old Testament; he cites them as Scripture in the same way; he attributes them to the respective authors whose names they bear; he regards them as writings handed down in the several Churches from the beginning; he fills his pages with quotations from them; he has not only a very thorough knowledge of their contents himself, but he assumes an acquaintance with and a recognition of them in his readers [262:1].

In the third book especially he undertakes to refute the opinions of his Valentinian opponents directly from the Scriptures. This leads him to be still more explicit. He relates briefly the circumstances under which our Four Gospels were written. He points out that the writings of the Evangelists arose directly from the oral Gospel of the Apostles. He shows that the traditional teaching of the Apostles has been preserved by a direct succession of elders which in the principal Churches can be traced man by man, and he asserts that this teaching accords entirely with the Evangelical and Apostolic writings. He maintains on the other hand, that the doctrine of the heretics was of comparatively recent growth. He assumes throughout, not only that our four Canonical Gospels alone were acknowledged in the Church in his own time, but that this had been so from the beginning. His Valentinian antagonists indeed accepted these same Gospels, paying especial deference to the Fourth Evangelist; and accordingly he argues with them on this basis. But they also superadded other writings, to which they appealed, while heretics of a different type, as Marcion for instance, adopted some one Gospel to the exclusion of all others. He therefore urges not only that four Gospels alone have been handed down from the beginning, but that in the nature of things there could not be more nor less than four. There are four regions of the world, and four principal winds; and the Church therefore, as destined to be conterminous with the world, must be supported by four Gospels, as four pillars. The Word again is represented as seated on the Cherubim, who are described by Ezekiel as four living creatures, each different from the other. These symbolize the four Evangelists, with their several characteristics. The predominance of the number four again appears in another way. There are four general covenants, of Noah, of Abraham, of Moses, of Christ. It is therefore an act of audacious folly to increase or diminish the number of the Gospels. As there is fitness and order in all the other works of God, so also we may expect to find it in the case of the Gospel.

What is the historical significance of this phenomenon? Can we imagine that the documents which Irenæus regards in this light had been produced during his own lifetime? that they had sprung up suddenly full-armed from the earth, no one could say how? and that they had taken their position at once by the side of the Law and the Psalmist and the Prophets, as the very voice of God?

The author of Supernatural Religion seems to think that no explanation is needed. 'The reasons,' he writes, 'which he [Irenæus] gives for the existence of precisely that number [four Gospels] in the Canon of the Church illustrate the thoroughly uncritical character of the Fathers, and the slight dependence which can be placed upon their judgments' [263:1]. Accordingly he does not even discuss the testimony of Irenæus, but treats it as if it were not. He does not see that there is all the difference in, the world between the value of the same man's evidence as to matters of fact, and his opinions as to the causes and bearings of his facts. He does not observe that these fanciful arguments and shadowy analogies are pro tanto an evidence of the firm hold which this quadruple Gospel, as a fact, had already obtained when he wrote. Above all, I must suppose from his silence that he regards this testimony of Irenæus in the isolated opinion of an individual writer, and is unconscious of the historical background which it implies. It is this last consideration which led me to speak of Irenæus as the most important witness to the early date and authorship of the Gospels, and to which I wish to direct attention.

The birth of Irenæus has been placed as early as A.D. 97 by Dodwell, and as late as A.D. 140 by our author and some others, while other writers again have adopted intermediate positions. I must frankly say that the very early date seems to me quite untenable. On the other hand, those who have placed it as late as A.D. 140 have chosen this date on the ground of the relation of Irenæus to Polycarp in his old age [264:1], and on the supposition that Polycarp was martyred about A.D. 167. Since however it has recently been shown that Polycarp suffered A.D. 155 or 156 [264:2], it may be presumed that these critics would now throw the date of his pupil's birth some ten or twelve years farther back, i.e. to about A.D. 128 or 130. But there is no reason why it should not have been some few years earlier. If the suggestion which I have thrown out in a previous paper deserves attention [265:1], he was probably born about A.D. 120. But the exact date of his birth is a matter of comparatively little moment. The really important fact is, that he was connected directly with the Apostles and the Apostolic age by two distinct personal links, if not more.

Of his connection with POLYCARP I have already spoken [265:2]. Polycarp was the disciple of St John; and, as he was at least eighty-six years old when he suffered martyrdom (A.D. 155), he must have been close upon thirty when the Apostle died. Irenæus was young when he received instruction from Polycarp. He speaks of himself in one passage as 'still a boy,' in another as 'in early life.' If we reckon his age as from fifteen to eighteen, we shall probably not be far wrong, though the expressions themselves would admit some latitude on either side. At all events, he says that he had a vivid recollection of his master's conversations; he recalled not only the substance of his discourses, but his very expressions and manner; more especially he states that he remembers distinctly his descriptions of his intercourse with John and other personal disciples of Christ together with their account of the Lord's life and teaching; and he adds that these were 'altogether in accordance with the Scriptures' [265:3].

But Irenæus was linked with the Apostolic age by another companionship also. He was the leading presbyter in the Church of Lyons, of which POTHINUS was bishop, and succeeded to this see on the martyrdom of the latter in A.D. 177 or 178. With Pothinus therefore he must have had almost daily intercourse. But Pothinus lived to be more than ninety years old, and must have been a boy of ten at least, when the Apostle St John died. Moreover there is every reason to believe, as we have already seen [265:4], that like Irenæus himself Pothinus came originally from Asia Minor. Under any circumstances, his long life and influential position would give a special value to his testimony respecting the past history of the Church; and, whether he was uncritical or not (of which we are ignorant), he must have known whether certain writings attributed to the Evangelists and Apostles had been in circulation as long as he could remember, or whether they came to his knowledge only the other day, when he was already advanced in life.

In one passage in his extant work, Irenæus gives an account of elaborate discourses which he had heard from an elder who had himself 'listened to those who had seen the Apostles and to those who had been disciples,' i.e. personal followers of Christ [266:1]. It seems most natural to identify this anonymous elder with Pothinus. In this case the 'disciples' whom he had heard would be such persons as Aristion and John the presbyter, who are mentioned in this same way by Papias; while under the designation of 'those who had seen the Apostles' Polycarp more especially might be intended. But, if he were not Pothinus, then he forms a third direct link of connection between Irenæus and the Apostolic age. Whoever he was, it is clear that the intercourse of Irenæus with him was frequent and intimate. 'The elder,' writes Irenæus, 'used to say,' 'The elder used to refresh us with such accounts of the ancient worthies,' 'The elder used to discuss.' Indeed the elaborate character of these discourses suggests, as I have stated in a former paper [266:2], that Irenæus is here reproducing notes of lectures which he had heard from this person. With the references direct or indirect to the Canonical writings in this anonymous teacher I am not concerned here; nor indeed is it necessary to add anything to what has been said in a previous paper [266:3]. I wish now merely to call attention to these discourses as showing, that through his intercourse with this elder Irenæus could not fail to have ascertained the mind of the earlier Church with regard to the Evangelical and Apostolic writings.

Nor were these the only exceptional advantages which Irenæus enjoyed. When he speaks of the recognition of the Canonical writings his testimony must be regarded as directly representing three Churches at least. In youth he was brought up, as we saw, in Asia Minor. In middle life he stayed for some time in Rome, having gone there on an important public mission [267:1]. Before and after this epoch he for many years held a prominent position in the Church of Gaul. He was moreover actively engaged from the beginning to the end of his public career in all the most important controversies of the day. He gave lectures as we happen to know; for Hippolytus attended a course on 'All the Heresies,' delivered perhaps during one of his sojourns at Rome [267:2]. He was a diligent letter-writer, interesting himself in the difficulties and dissensions of distant Churches, and more than one notice of such letters is preserved. He composed several treatises more or less elaborate, whose general character may be estimated from his extant work. The subjects moreover, with which he had to deal, must have forced him to an examination of the points with which we are immediately concerned. He took a chief part in the Montanist controversy; and the Montanist doctrine of the Paraclete, as I have before had occasion to remark [267:3], directly suggested an investigation of the promise in the Fourth Gospel. He was equally prominent in the Paschal dispute, and here again the relation between the narratives of St John and the Synoptists must have entered largely into the discussion. He was contending all his life with Gnostics, or reactionists against Gnosticism, and how large a part the authority and contents of the Gospels and Epistles must have played in these controversies generally we see plainly from his surviving work against the Valentinians.
