In addition to the above testimonies might be adduced some fragments of early Christian writers which have been preserved to us by those of a later day; but for brevity's sake they are omitted.

10. Following up the stream of testimony, we come now to that of the so-called apostolic fathers; that is, of men who were disciples of apostles, and wrote in the age next following them. Holding, as they do, such a near relation to the apostles, and familiar with the oral traditions of the apostolic age, we cannot expect to find in them such frequent and formal references to the books of the New Testament as characterize the works of later writers. They quote, for the most part, anonymously, interweaving with their own words those of the sacred writers.

One of the earliest among the apostolic fathers is Clement of Rome, who died about A.D. 100. Of the numerous writings anciently ascribed to him, his First Epistle to the Corinthians is admitted, upon good evidence, to be genuine. In this we find words which imply a knowledge of the first three gospels. Citing evidently from memory, in a loose way, he says: "For thus he"—the Lord Jesus—"spake, 'Be merciful, that ye may obtain mercy; forgive, that ye may be forgiven; as ye do, so shall it be done to you; as ye give, so shall it be given to you; as ye judge, so shall ye receive judgment; as ye are kind, so shall ye receive kindness; with what measure ye measure, with that it shall be measured to you.'" And again: "For he said, 'Woe unto that man; it were better for him that he had not been born, than that he should offend one of my elect.'"

Ignatius was bishop of the church at Antioch, and suffered martyrdom A.D. 107, or according to some accounts, 116. In his epistles, which are received as genuine, are manifest quotations from the gospel of Matthew, and some apparent though not entirely certain allusions to the gospel of John.

Polycarp, bishop of Smyrna, was a disciple of the apostle John. He suffered martyrdom about the year 166. Of his writings, only one short epistle, addressed to the Philippians, remains to us; but this abounds in references to the books of the New Testament, especially the epistles of Paul. Of quotations from the gospel of Matthew, the following are examples: "Judge not, that ye be not judged; forgive, and ye shall be forgiven; be merciful, that ye may obtain mercy; with what measure ye mete, it shall be measured to you again." "Blessed are the poor in spirit, and those that suffer persecution for righteousness' sake, for theirs is the kingdom of heaven." "The spirit indeed is willing, but the flesh is weak." For the gospel of John, Polycarp's testimony, though indirect, is decisive. In his letter to the Philippians, he quotes from the First Epistle of John, "For every one who does not confess that Jesus Christ has come in the flesh, is antichrist." 1 John 4:3. But that the gospel of John and this first epistle both proceeded from the same author, is a conceded fact.

The recently discovered Sinai Codex, the oldest known codex in the world, contains the entire Epistle of Barnabas in the original Greek. In this we find, among other references to the first three gospels, one to the written gospel of Matthew of the most decisive character: "Let us be mindful, therefore, lest perchance we be found as it is written, 'Many are called, but few are chosen.'" Matt. 20:16; 22:14. The form of quotation, "as it is written," is employed by the writers of the New Testament only of citations from Scripture. In these words the writer places the gospel of Matthew in the same rank as the Scriptures of the Old Testament. That he was the Barnabas mentioned in the New Testament as the companion of Paul cannot be maintained; but the composition of the epistle is assigned, with probability, to the beginning of the second century, though some place it as late as its close.

The testimony of other apocryphal writings of early date might be adduced, but for the sake of brevity it is here omitted. It may be seen in the essay of Tischendorf, already referred to.

11. A different class of witnesses will next be considered—the ancient Syriac version, the old Latin version, and the Muratorian fragment on the canon of the New Testament—all of which bear testimony to our canonical gospels.

The ancient Syriac version, commonly called the Peshito—simple, that is, expressing simply the meaning of the original, without allegorical additions and explanations, after the manner of the Jewish Targums—is admitted by all to be of very high antiquity. Learned men are agreed that this version cannot well be referred to a later date than the close of the second century, and some assign it to the middle of the second century, at which time the Syrian churches were in a very flourishing condition, and cannot well be supposed to have been without a version of the Holy Scriptures. The Peshito contains all the books of the New Testament, except the Second Epistle of Peter, the Second and Third Epistles of John, the Epistle of Jude, and the Apocalypse. It testifies to the existence of our four gospels, not only when it was made, but at an earlier date; since we must, in all probability, assume that some considerable time elapsed after the composition, one by one, of the books of the New Testament, before they were collected into a volume, as in this Syriac version.

Respecting the Old Latin version, (in distinction from Jerome's revision, commonly called the Vulgate, which belongs to the fourth century,) various opinions have been maintained. Some have assumed the existence of several independent Latin versions of the New Testament, or of some of its books; but the preferable opinion is that there were various recensions, all having for their foundation a single version, namely, the Old Latin; which, says Westcott, Canon of the New Testament, ch. 3, "can be traced back as far as the earliest records of Latin Christianity. Every circumstance connected with it indicates the most remote antiquity." It was current in north Africa, at least soon after the middle of the second century. Though it has not come down to us in a perfect form, it contains, along with most of the other books of the New Testament, our four canonical gospels; and its testimony is of the greatest weight.

The Muratorian Fragment on the Canon is the name given to a Latin fragment discovered by the Italian scholar, Muratori, in the Ambrosian Library at Milan, in a manuscript bearing the marks of great antiquity. Its date is determined by its reference to the shepherd of Hermas, which, says the Fragment, Hermas "wrote very recently in our times, while the bishop Pius, his brother, occupied the chair of the church at Rome." The later of the two dates given for the death of Pius is A.D. 157. The composition of the Fragment must have followed soon afterwards. Though mutilated at the beginning, as well as the end, its testimony to the existence of the four canonical gospels is decisive. In its present form, it opens with the end of a sentence, the beginning of which is lost. It then goes on to say, "The third gospel according to Luke." After mentioning various particulars concerning Luke, as that he was a physician whom Paul had taken with him, that he did not himself see the Lord in the flesh, etc., it adds, "The fourth of the gospels, that of John, of the number of the disciples," to which it appends a traditional account of the circumstances of its composition. With the truth or falsehood of this account we have at present no concern; the important fact is that this very ancient canon recognizes the existence of our four canonical gospels.

12. The heretical sects of the second century furnish testimony to the genuineness of our canonical gospels which is of the most weighty and decisive character. Though some of them rejected certain books of the New Testament and mutilated others, it was on doctrinal, not on critical grounds. Had they attempted to disprove on historic grounds the genuineness of the rejected portions of Scripture, it is certain that the church fathers, who wrote against them at such length, would have noticed their arguments. The fact that they did not, is conclusive proof that no such attempt was made; but from the position which the leaders of these heretical sects occupied, it is certain that, could the genuineness of the canonical gospels, or any one of them, have been denied on historic grounds, the denial would have been made.

Marcion, one of the most distinguished leaders of those who separated themselves from the orthodox church, came to Rome in the second quarter of the second century. He separated Christianity from all connection with Judaism, making the Jehovah of the Old Testament a different being from the God of the New Testament. His gospel, called by the ancients the gospel of Marcion, is admitted to have been a mutilated copy of Luke's gospel. Of course it became necessary that he should reject the first two chapters of this gospel, (which alone he received,) since they contain our Lord's genealogy in the line of Abraham and David, and should otherwise alter it to suit his views. On the same grounds, he altered the epistles of Paul also. That Marcion was not ignorant of the other three gospels, but rejected them, is plain from the words of Tertullian, who accuses him, Against Marcion, 4. 3, of attempting "to destroy the credit of those gospels which are properly such, and are published under the name of apostles, or also of apostolic men; that he may invest his own gospel with the confidence which he withdraws from them." His real ground for rejecting some books of the New Testament and mutilating others was that he could judge better of the truth than the writers themselves, whom he represented to have been misled by the influences of Jewish prejudices. Accordingly Irenæus well says of the liberties taken by Marcion, Against Heresies, 1. 27: "He persuaded his disciples that he was himself more trustworthy than the apostles who have delivered to us the gospel; while he gave to them not the gospel, but a fragment of the gospel."

A distinguished leader of the Gnostics was Valentinus, who came to Rome about A.D. 140, and continued there till the time of Anicetus. His testimony and that of his followers is, if possible, more weighty than even that of Marcion. His method, according to the testimony of Tertullian, was not to reject and mutilate the Scriptures, but to pervert their meaning by false interpretations. Tertullian says, Against Heretics, ch. 38: "For though Valentinus seems to use the entire instrument, he has done violence to the truth with a more artful mind than Marcion." "The entire instrument"—Latin, integro instrumento—includes our four canonical gospels. Clement of Alexandria and Hippolytus have preserved quotations from Valentinus in which he refers to the gospels of Matthew, Luke, and John. See Westcott, Canon of the New Testament, 4. 5. Respecting the gospel of John in particular, Irenæus says, Against Heresies, 3. 11, that "the Valentinians make the most abundant use of it." Heracleon, whom Origen represents as having been a familiar friend of Valentinus, wrote a commentary on John, from which Origen frequently quotes; but if Valentinus and his followers, in the second quarter of the second century, used "the entire instrument," they must have found its apostolic authority established upon a firm foundation before their day. This carries us back to the age immediately succeeding that of the apostles, when Polycarp and others who had known them personally were yet living. The testimony of the Valentinians, then, is of the most decisive character.

Another prominent man among the heretical writers was Tatian, a contemporary and pupil of Justin Martyr, who, according to the testimony of Eusebius, Epiphanius, and Theodoret, composed a Diatessaron, that is, a four-fold gospel; which can be understood only as a harmony of the four gospels which, as has been shown, were used by Justin; or of such parts of these gospels as suited his purpose; for Tatian, like Marcion, omitted all that relates to our Lord's human descent. With this Diatessaron, Theodoret was well acquainted; for he found among his churches more than two hundred copies, which he caused to be removed, and their places supplied by the four canonical gospels.

As to other gospels of the second century, which are occasionally mentioned by later writers, as "The Gospel of Truth," "The Gospel of Basilides," etc., there is no evidence that they professed to be connected histories of our Lord's life and teachings. They were rather, as Norton has shown, Genuineness of the Gospels, vol. 3, chap. 4, doctrinal works embodying the views of the sectaries that used them.

13. We have seen how full and satisfactory is the external evidence for our four canonical gospels. Considering how scanty are the remains of Christian writings that have come down to us from the first half of the same century, we have all the external evidence for that period also that could be reasonably demanded, and it is met by no rebutting testimony that rests on historic grounds. The authorship of no ancient classical work is sustained by a mass of evidence so great and varied, and the candid mind can rest in it with entire satisfaction.

III. Internal Evidences. 14. Here we may begin with considering the relation of the first three gospels to the last, in respect to both time of composition and character.
