II. External Evidences. 4. Here we need not begin at a later date than the last quarter of the second century. This is the age of Irenæus in Gaul, of Tertullian in North Africa, of Clement of Alexandria in Egypt, and of some other writers. Their testimony to the apostolic origin and universal reception of our four canonical gospels is as full as can be desired. They give the names of the authors, two of them—Matthew and John—apostles, and the other two—Mark and Luke—companions of apostles and fellow-laborers with them, always associating Mark with Peter, and Luke with Paul; they affirm the universal and undisputed reception of these four gospels from the beginning by all the churches; and deny the apostolic authority of other pretended gospels. In all this, they give not their individual opinions, but the common belief of the churches. It is conceded on all hands that in their day these four gospels were universally received by the churches as genuine and authoritative records of our Lord's life and works, to the exclusion of all others.
Irenæus was a native of Asia Minor, of Greek descent; but the seat of his labors was Lyons and Vienne in Gaul, of the former of which places he became bishop after the martyrdom of Pothinus, about A.D. 177. He was born about A.D. 140, and suffered martyrdom under Septimius Severus A.D. 202. In his youth he was a disciple of Polycarp, who was in turn a disciple of the apostle John. In a letter to one Florinus, which Eusebius has preserved, (Hist. Eccl., 5. 20,) he gives, in glowing language, his recollections of the person and teachings of Polycarp, and tells with what interest he listened as this man related his intercourse with the apostle John and the others who had seen the Lord, "how he recounted their words, and the things which he had heard from them concerning the Lord, and concerning his miracles and teaching." And he adds that these things which Polycarp had received from eye-witnesses he related "all in agreement with the Scriptures;" that is, obviously, with the gospel narratives. Pothinus, the predecessor of Irenæus at Lyons, was ninety years old at the time of his martyrdom, and must have been acquainted with many who belonged to the latter part of the apostolic age. Under such circumstances, it is inconceivable that Irenæus, who knew the Christian traditions of both the East and the West, should not have known the truth respecting the reception of the gospels by the churches, and the grounds on which this reception rested, more especially in the case of the gospel of John. Tischendorf, after mentioning the relation of Irenæus to Polycarp the disciple of John, asks, with reason: "Are we, nevertheless, to cherish the supposition that Irenæus never heard a word from Polycarp respecting the gospel of John, and yet gave it his unconditional confidence—this man Irenæus, who in his controversies with heretics, the men of falsification and apocryphal works, employs against them, before all other things, the pure Scripture as a holy weapon?" (Essay, When were Our Gospels Written, p. 8.) The testimony of Irenæus is justly regarded as of the most weighty character. The fact that he gives several fanciful reasons why there should be only four gospels, (Against Heresies, 3. 11,) does not invalidate his statement of the fact that the churches had always received four, and no more. We always distinguish between men's testimony to facts of which they are competent witnesses, and their philosophical explanations of these facts.
Tertullian was born in Carthage about A.D. 160, and died between A.D. 220 and 240. About A.D. 202 he joined the sect of the Montanists; but this does not affect his testimony respecting the origin and universal reception of the four canonical gospels. His works are very numerous, and in them all he insists with great earnestness that the gospel narratives, as also the other apostolic writings, have been received without corruption, as a sacred inheritance, from the apostolic churches. His work against Marcion, whom he accuses of employing a mutilated gospel of Luke, is particularly instructive as showing how deep and settled was the conviction of the early Christians that nothing could be a gospel which did not proceed from apostles or apostolic men; and how watchful they were against all attempts to mutilate or corrupt the primitive apostolic records. In defending the true gospel of Luke against the mutilated form of it employed by Marcion, he says: "I affirm that not in the apostolic churches alone, but in all which are joined with them in the bond of fellowship, that gospel of Luke which we most firmly maintain, has been valid from its first publication; but Marcion's gospel is unknown to most of them, and known to none, except to be condemned." This testimony of Tertullian is very important, as showing his full conviction that Marcion could not deny the universal reception, from the beginning, of the genuine gospel of Luke. And a little afterwards he adds: "The same authority of the apostolic churches will defend the other gospels also, which we have in like manner through them, and according to them," (Against Marcion, 4. 5.) Many more quotations of like purport might be added.
Clement of Alexandria was a pupil of Pantænus, and his successor as head of the catechetical school at Alexandria in Egypt. He was of heathen origin, born probably about the middle of the second century, and died about A.D. 220. He had a philosophical turn of mind, and after his conversion to Christianity made extensive researches under various teachers, as he himself tells us, in Greece, in Italy, in Palestine, and other parts of the East. At last he met with Pantænus in Egypt, whom he preferred to all his other guides, and in whose instructions he rested. The testimony of Clement to the universal and undisputed reception by the churches of the four canonical gospels as the writings of apostles or apostolic men, agrees with that of Tertullian. And it has the more weight, not only on account of his wide investigations, but because, also, it virtually contains the testimony of his several teachers, some of whom must have known, if not the apostles themselves, those who had listened to their teachings.
In connection with the testimony of the above-named writers, we may consider that of the churches of Lyons and Vienne in Gaul, in a letter addressed by them to "the churches of Asia and Phrygia," which Eusebius has preserved for us, (Hist. Eccl., 5. 1,) and which describes a severe persecution through which they passed in the reign of Antoninus Verus, about A.D. 177. In this they say: "So was fulfilled that which was spoken by our Lord, 'The time shall come in which whosoever killeth you shall think that he doeth God service.'" In speaking again of a certain youthful martyr, they first compare him to Zacharias, the father of John the Baptist, affirming, in the very words of Luke, that he "had walked in all the commandments and ordinances of the Lord blameless," (Luke 1:6;) and then go on to describe him as "having the Comforter in himself, the Spirit, more abundantly than Zacharias," where they apply to the Holy Spirit a term peculiar to the apostle John. Here, then, we have indubitable testimony to the fact that the gospel of John, as well as of Luke, was known to the churches of Gaul in the west and Asia Minor in the east in the days of Pothinus, bishop of these churches, who suffered martyrdom in this persecution. But Pothinus was ninety years old, so that his knowledge of these gospels must have reached back to the first quarter of the second century, when many who had known the apostles were yet living.
5. These testimonies, let it be carefully remembered, apply not to one part of Christendom alone, but to all its different and distant divisions; and that, too, long before there was any attempt to bring the judgment of the churches into harmony by means of general councils. The orthodox churches planted in the different provinces of the Roman empire, though in substantial harmony with each other, had nevertheless their minor differences, which were sometimes discussed with much warmth. In their relation to each other, they were jealous of their freedom and independence. The history of the so-called Antilegomena (Disputed Books of the New Testament, chap. 6) shows that the reception of a writing as apostolic in one division of Christendom, did not insure its reception elsewhere. Had it been possible that a spurious book should be imposed as genuine on the churches of one region, it would certainly have met with opposition in other regions; but our four canonical gospels were everywhere received without dispute as the writings of apostles or apostolic men. This fact admits of but one explanation: the churches had from their first appearance indubitable evidence of their genuineness.
6. Let it be further remembered that this testimony relates not to books of a private character, that might have lain for years hidden in some corner; but to the public writings of the churches, on which their faith was founded, of which they all had copies, and which it was the custom, from the apostolic age, to read in their assemblies along with the law and the prophets. (Justin Martyr Apol., 1. 67.) Earnestness and sincerity are traits which will not be denied to the primitive Christians, and they were certainly not wanting in common discernment. Let any man show, if he can, how a spurious gospel, suddenly appearing somewhere after the apostolic days, could have been imposed upon the churches as genuine, not only where it originated, but everywhere else in Christendom. The difficulty with which some of the genuine books of the New Testament gained universal currency sufficiently refutes such an absurd supposition.
7. We are now prepared to consider the testimonies of an earlier period. Here Justin Martyr is a very weighty witness, since he lived so near the apostolic age, and had every facility for investigating the history of the gospel narratives. He was born near the beginning of the second century, and his extant works date from about the middle of the same century. Before his conversion to Christianity he was a heathen philosopher earnestly seeking for the truth among the different systems of the age. Of his undoubtedly genuine works, there remain to us two Apologies (defences of Christianity) and a Dialogue with Trypho a Jew, designed to defend the Christian religion against its Jewish opponents. In these he quotes the gospel of Matthew very abundantly; next in number are his quotations from Luke. His references to Mark and John are much fewer, but enough to show his acquaintance with them. He never quotes the evangelists by name, but designates their writings as "The Memoirs of the Apostles;" and more fully, "The memoirs which I affirm to have been composed by his"—our Lord's—"apostles and their followers," Dialog., ch. 103, "which," he elsewhere says, "are called gospels," Apol. 1. 66, and in a collective sense, "the gospel," Dialog., ch. 10. It should be carefully noticed that he speaks in the plural number both of the apostles who composed the gospels and their followers. This description applies exactly to our canonical gospels—two written by apostles, and two by their followers.
The attempt has been made in modern times to set aside Justin's testimony, on the alleged ground that he quotes not from our canonical gospels, but from some other writings. The groundlessness of this supposition is manifest at first sight. Justin had visited the three principal churches of Rome, Alexandria, and Ephesus. It is certain that he knew what gospels were received by them in his day as authentic, and that these are the very gospels which he quotes, affirming that they were the writings of apostles and their followers. Now, that the gospels which Justin used should have been wholly supplanted by others in the days of Irenæus, who was of full age at the time of Justin's death, is incredible. But Irenæus, in common with Clement, Tertullian, and others, quotes our four canonical gospels as alone possessing apostolic authority, and as having been always received by the churches. It follows that the "Memoirs" of Justin must be the same gospels. We cannot conceive that in this brief period an entire change of gospels should have been made throughout all the different and distant provinces of the Roman empire, at a time when concerted action through general councils was unknown; and that, too, in so silent a manner that no record of it remains in the history of the church. The supposition that the gospels known to Justin were different from those received by Irenæus ought not to be entertained without irrefragable proof. But no such proof exists. "An accurate examination in detail of his citations," says Semisch, Life of Justin Martyr, 4. 1, "has led to the result that this title"—the Memoirs of the Apostles—"designates the canonical gospels—a result in no way less certain because again called in question in modern days."
The agreement of his quotations with our present gospels is of such a character and extent as can be explained only from his use of them. The variations are mainly due to his habit of quoting loosely from memory. "Many of these citations," says Kirchhofer, "agree, word for word, with the gospels; others with the substance, but with alterations and additions of words, with transpositions and omissions; others give the thought only in a general way; others still condense together the contents of several passages and different sayings, in which case the historic quotations are yet more free, and blend together, in part, the accounts of Matthew and Luke. But some quotations are not found at all in our canonical gospels," (see immediately below;) "some, on the contrary, occur twice or thrice." Quellensammlung, p. 89. note. Two or three more important variations are, perhaps, due to the readings in the manuscripts employed by Justin, since the later church fathers, who, as we know, employed the canonical gospels, give the same variations. Finally, Justin gives a few incidents and sayings not recorded in our present gospels. As he lived so near the apostolic times he may well have received these from tradition; but if in any case he took them from written documents, there is no proof that he ascribed to such documents apostolic authority. In one passage, he accurately distinguishes between what he gives from tradition or other written sources, and what from the apostolic records. "When Jesus came," he says, "to the river Jordan, where John was baptizing, as he descended to the water, both was a fire kindled in the Jordan, and as he ascended from the water, the apostles of this very Christ of ours have written that the Holy Spirit as a dove lighted upon him." Dial., ch. 88.
It has been doubted whether certain references to the gospel of John can be found in Justin's writings; but it seems plain that the following is a free quotation from chapter 3:3-5: "For Christ said, Except ye be born again, ye shall by no means enter into the kingdom of heaven. But that it is impossible that they who have once been born should enter into the wombs of those who bare them is manifest to all." Apol. 1. 61. To affirm that a passage so peculiar as this was borrowed by both the evangelist John and Justin from a common tradition, is to substitute a very improbable for a very natural explanation. Besides, Justin uses phraseology peculiar to John, repeatedly calling our Saviour "the Word of God," and "the Word made flesh;" affirming that he "was in a peculiar sense begotten the only Son of God," "an only begotten One to the Father of all things, being in a peculiar sense begotten of him as Word and Power, and afterwards made man through the Virgin;" and calling him "the good Rock that sends forth (literally, causes to bubble forth—compare John 4:14) living waters into the hearts of those who through him have loved the Father of all things, and that gives to all who will the water of life to drink." These and other references to John may be seen in Kirchhofer's Quellensammlung, pp. 146, 147.
8. Another early witness is Papias, who was bishop of Hierapolis, in Phrygia, in the first half of the second century. He wrote "An Exposition of the Oracles of the Lord," in five books. This work has perished; but fragments of it, with notices of its contents, are preserved to us by Eusebius and other writers. As Papias, according to his own express testimony, gathered his materials, if not from apostles themselves, yet from their immediate disciples, his statements are invested with great interest. Of Matthew he says, Eusebius Hist. Eccl., 5. 39, that he "wrote the oracles in the Hebrew dialect, and every one interpreted them as he could." He speaks of this interpretation by each one as he could as something past, implying that in his day our present Greek gospel of Matthew (of the apostolic authority of which there was never any doubt in the early churches) was in circulation, whether it was or was not originally composed in Hebrew, a question on which learned men are not agreed. Of Mark he affirms that, "having become Peter's interpreter, he wrote down accurately as many things as he remembered; not recording in order the things that were said or done by Christ, since he was not a hearer or follower of the Lord, but afterwards"—after our Lord's ascension—"of Peter, who imparted his teachings as occasion required, but not as making an orderly narrative of the Lord's discourses." Hist. Eccl., 3. 39. The fact that Eusebius gives no statement of Papias respecting the other two gospels is of little account, since his notices of the authors to whom he refers, and of their works, are confessedly imperfect.
Eusebius notices, for example, Hist. Eccl. 4. 14, the fact that Polycarp, in his letter to the Philippians, "has used certain testimonies from the First Epistle of Peter;" but says nothing of his many references, in the same letter, to the epistles of Paul, in some of which he quotes the apostle by name. We have, nevertheless, through Eusebius, an indirect but valid testimony from Papias to the authorship of the fourth gospel, resting upon the admitted identity of the author of this gospel with the author of the first of the epistles ascribed to John. Speaking of Papias, Eusebius says: "But the same man used testimonies from the First Epistle of John." Hist. Eccl., 3. 39, end. The ascription to John of this epistle, is virtually the ascription to him of the fourth gospel also. Eusebius speaks of Papias as a man "of very small mind." The correctness of this judgment is manifest from the specimens which he gives of his writings; but it cannot invalidate the evidence we have from the above passages of the existence, in Papias' day, of the gospels to which he refers. As to the question whether these were our present canonical gospels of Matthew and Mark, it is sufficient to say that neither Eusebius nor any of the church fathers understood them differently.
9. A very interesting relic of antiquity is the Epistle to Diognetus, of which the authorship is uncertain. Its date cannot be later than the age of Justin Martyr, to whom it is ascribed by some. It is, notwithstanding some erroneous views, a noble defence of Christianity, in which the author shows his acquaintance with the gospel of John by the use of terms and phrases peculiar to him. Thus he calls Christ "the Word," and "the only begotten Son," whom God sent to men. In the words, "not to take thought about raiment and food," section 9, there is an apparent reference to Matt. 6:25, 31.
