Then we have the admitted individual testimonies of all the Greek and Latin fathers up to the middle of the second century, without a dissenting voice or doubt: Jerome (d. 419) and Eusebius (d. 340), who had the whole ante-Nicene literature before them; Origen in Egypt (d. 254), the greatest scholar of his age and a commentator on John; Tertullian of North Africa (about 200), a Catholic in doctrine, a Montanist in discipline, and a zealous advocate of the dispensation of the Paraclete announced by John; Clement of Alexandria (about 190), a cultivated philosopher who had travelled in Greece, Italy, Syria, and Palestine, seeking religious instruction everywhere; Irenaeus, a native of Asia Minor and from 178 bishop of Lyons, a pupil of Polycarp and a grand-pupil of John himself, who derived his chief ammunition against the Gnostic heresy from the fourth Gospel, and represents the four canonical Gospels--no more and no less--as universally accepted by the churches of his time; Theophilus of Antioch (180), who expressly quotes from the fourth Gospel under the name of John; [1061] the Muratorian Canon (170), which reports the occasion of the composition of John's Gospel by urgent request of his friends and disciples; Tatian of Syria (155-170), who in his "Address to the Greeks" repeatedly quotes the fourth Gospel, though without naming the author, and who began his, "Diatessaron"--once widely spread in the church notwithstanding the somewhat Gnostic leanings of the author, and commented on by Ephraem of Syria--with the prologue of John. [1062] From him we have but one step to his teacher, Justin Martyr, a native of Palestine (103-166), and a bold and noble-minded defender of the faith in the reigns of Hadrian and the Antonines. In his two Apologies and his Dialogue with Trypho the Jew, he often quotes freely from the four Gospels under the name of Apostolic "Memoirs" or "Memorabilia of the Apostles," which were read at his time in public, worship. [1063] He made most use of Matthew, but once at least he quotes a passage on regeneration [1064] from Christ's dialogue with Nicodemus which is recorded only by John. Several other allusions of Justin to John are unmistakable, and his whole doctrine of the pre-existent Logos who sowed precious seeds of truth among Jews and Gentiles before his incarnation, is unquestionably derived from John. To reverse the case is to derive the sunlight from the moon, or the fountain from one of its streams.
But we can go still farther back. The scanty writings of the Apostolic Fathers, so called, have very few allusions to the New Testament, and breathe the atmosphere of the primitive oral tradition. The author of the "Didache" was well acquainted with Matthew. The first Epistle of Clement has strong affinity with Paul. The shorter Epistles of Ignatius show the influence of John's Christology. [1065] Polycarp (d. a.d. 155 in extreme old age), a personal pupil of John, used the First Epistle of John, and thus furnishes an indirect testimony to the Gospel, since both these 'books must stand or fall together. [1066] The same is true of Papias (died about 150), who studied with Polycarp, and probably was likewise a bearer of John. He "used testimonies from the former Epistle of John." [1067] In enumerating the apostles whose living words he collected in his youth, he places John out of his regular order of precedence, along with Matthew, his fellow-Evangelist, and "Andrew, Peter, and Philip" in the same order as John 1:40-43; from which it has also been inferred that he knew the fourth Gospel. There is some reason to suppose that the disputed section on the woman taken in adultery was recorded by him in illustration of John 8:15; for, according to Eusebius, he mentioned a similar story in his lost work. [1068] These facts combined, make it at least extremely probable that Papias was familiar with John. [1069] The joint testimony of Polycarp and Papias represents the school of John in the very field of his later labors, and the succession was continued through Polycrates at Ephesus, through Melito at Sardis, through Claudius Apollinaris at Hieropolis, and Pothinus and Irenaeus in Southern Gaul. It is simply incredible that a spurious Gospel should have been smuggled into the churches under the name of their revered spiritual father and grandfather.
Finally, the concluding verse of the appendix, John 21:24, is a still older testimony of a number of personal friends and pupils of John, perhaps the very persons who, according to ancient tradition, urged him to write the Gospel. The book probably closed with the sentence: "This is the disciple who beareth witness of these things, and wrote these things." To this the elders add their attestation in the plural: "And we know that his witness is true." A literary fiction would not have been benefited by an anonymous postscript. The words as they, stand are either a false testimony of the pseudo-John, or the true testimony of the friends of the real John who first received his book and published it before or after his death.
The voice of the whole Catholic church, so far as it is heard, on the subject at all, is in favor of the authorship of John. There is not a shadow of proof to the contrary opinion except one, and that is purely negative and inconclusive. Baur to the very last laid the greatest stress on the entangled paschal controversy of the second century as a proof that John could not have written the fourth Gospel because he was quoted as an authority for the celebration of the Lord's Supper on the 14th of Nisan; while the fourth Gospel, in flat contradiction to the Synoptists, puts the crucifixion on that day (instead of the 15th), and represents Christ as the true paschal lamb slain at the very time when the typical Jewish passover was slain. But, in the first place, some of the ablest scholars know how to reconcile John with the Synoptic date of the crucifixion on the 15th of Nisan; and, secondly, there is no evidence at all that the apostle John celebrated Easter with the Quartodecimans on the 14th of Nisan in commemoration of the day of the Lord's Supper. The controversy was between conforming the celebration of the Christian Passover to the day of the month, that is to Jewish chronology, or to the day of the week on which Christ died. The former would have made Easter, more conveniently, a fixed festival like the Jewish Passover, the latter or Roman practice made it a movable feast, and this practice triumphed at the Council of Nicaea. [1070]
2. Heretical testimonies. They all the more important in view of their dissent from Catholic doctrine. It is remarkable that the heretics seem to have used and commented on the fourth Gospel even before the Catholic writers. The Clementine Homilies, besides several allusions, very clearly quote from the story of the man born blind, John 9:2, 3. [1071] The Gnostics of the second century, especially the Valentinians and Basilidians, made abundant use of the fourth Gospel, which alternately offended them by its historical realism, and attracted them by its idealism and mysticism. Heracleon, a pupil of Valentinus, wrote a commentary on it, of which Origen has preserved large extracts; Valentinus himself (according to Tertullian) tried either to explain it away, or he put his own meaning into it. Basilides, who flourished about a.d. 125, quoted from the Gospel of John such passages as the "true light, which enlighteneth every man was coming into the world" (John 1:9), and, my hour is not yet come "(2:4). [1072]
These heretical testimonies are almost decisive by themselves. The Gnostics would rather have rejected the fourth Gospel altogether, as Marcion actually did, from doctrinal objection. They certainly would not have received it from the Catholic church, as little as the church would have received it from the Gnostics. The concurrent reception of the Gospel by both at so early a date is conclusive evidence of its genuineness. "The Gnostics of that date," says Dr. Abbot, [1073] "received it because they could not help it. They would not have admitted the authority of a book which could be reconciled with their doctrines only by the most forced interpretation, if they could have destroyed its authority by denying its genuineness. Its genuineness could then be easily ascertained. Ephesus was one of the principal cities of the Eastern world, the centre of extensive commerce, the metropolis of Asia Minor. Hundreds, if not thousands, of people were living who had known the apostle John. The question whether he, the beloved disciple, had committed to writing his recollections of his Master's life and teaching, was one of the greatest interest. The fact of the reception of the fourth Gospel as his work at so early a date, by parties so violently opposed to each other, proves that the evidence of its genuineness was decisive. This argument is further confirmed by the use of the Gospel by the opposing parties in the later Montanistic controversy, and in the disputes about the time of celebrating Easter."
3. Heathen testimony. Celsus, in his book against Christianity, which was written about a.d. 178 (according to Keim, who reconstructed it from the fragments preserved in the refutation of Origen), derives his matter for attack from the four Gospels, though he does not name their authors, and he refers to several details which are peculiar to John, as, among others, the blood which flowed from the body of Jesus at his crucifixion (John 19:34), and the fact that Christ "after his death arose and showed the marks of his punishment, and how his hands had been pierced" (20:25, 27). [1074]
The radical assertion of Baur that no distinct trace of the fourth Gospel can be found before the last quarter of the second century has utterly broken down, and his own best pupils have been forced to make one concession after another as the successive discoveries of the many Gnostic quotations in the Philosophumena, the last book of the pseudo-Clementine Homilies, the Syrian Commentary on Tatian's Diatessaron, revealed the stubborn fact of the use and abuse of the Gospel before the middle and up to the very beginning of the second century, that is, to a time when it was simply impossible to mistake a pseudo-apostolic fiction for a genuine production of the patriarch of the apostolic age.
II. Internal Evidence. This is even still stronger, and leaves at last no alternative but truth or fraud.
1. To begin with the style of the fourth Gospel, we have already seen that it is altogether unique and without a parallel in post-apostolic literature, betraying a Hebrew of the Hebrews, impregnated with the genius of the Old Testament, in mode of thought and expression, in imagery and symbolism, in the symmetrical structure of sentences, in the simplicity and circumstantiality of narration; yet familiar with pure Greek, from long residence among Greeks. This is just what we should expect from John at Ephesus. Though not a rabbinical scholar, like Paul, he was acquainted with the Hebrew Scriptures and not dependent on the Septuagint. He has in all fourteen quotations from the Old Testament. [1075] Four of these agree with the Hebrew and the Septuagint; three agree with the Hebrew against the Septuagint (6:45; 13:18 19:37), the rest are neutral, either agreeing with both or differing from both, or being free adaptations rather than citations; but none of them agrees with the Septuagint against the Hebrew. [1076]
Among the post-apostolic writers there is no converted Jew, unless it be Hegesippus; none who could read the Hebrew and write Hebraistic Greek. After the destruction of Jerusalem the church finally separated from the synagogue and both assumed an attitude of uncompromising hostility.
2. The author was a Jew of Palestine. He gives, incidentally and without effort, unmistakable evidence of minute familiarity with the Holy Land and its inhabitants before the destruction of Jerusalem. He is at home in the localities of the holy city and the neighborhood. He describes Bethesda as "a pool by the sheep gate, having five porches" (5:2), Siloam as "a pool which is by interpretation Sent" (9:7), Solomon's porch as being "in the Temple" (10:23), the brook Kedron "where was a garden" (18:1); he knows the location of the praetorium (18:28), the meaning of Gabbatha (19:13), and Golgotha (19:17), the distance of Bethany from Jerusalem "about fifteen furlongs off" (11:18), and he distinguishes it from Bethany beyond Jordan (1:28). He gives the date when the Herodian reconstruction of the temple began (2:19). He is equally familiar with other parts of Palestine and makes no mistakes such as are so often made by foreigners. He locates Cana in Galilee (2:1; 4:26 21:2), to distinguish it from another Cana; Aenon "near to Salim" where there are "many waters" (3:23); Sychar in Samaria near "Jacob's, well," and in view of Mount Gerizim (4:5). He knows the extent of the Lake of Tiberias (6:19); he describes Bethsaida as "the city of Andrew and Peter" (1:44), as distinct from Bethsaida Julias on the eastern bank of the Jordan; he represents Nazareth as a place of proverbial insignificance (1:46).
