THE EXTERNAL EVIDENCE FOR THE FOURTH GOSPEL.
The fourth Gospel was, upon any theory, written later than the others, and it is not clear that it was published as soon as it was written. Both tradition and the internal evidence of the concluding chapter seem to point to the existence of somewhat peculiar relations between the Evangelist and the presbyters of the Asian Church, which would make it not improbable that the Gospel was retained for some time by the latter within their own private circle before it was given to the Church at large.
We have the express statement of Irenaeus [Endnote 269:1], who, if he was born as is commonly supposed at Smyrna about 140 A.D., must be a good authority, that the Apostle St. John lived on till the times of Trajan (98-117 A.D.). If so, it is very possible that the Gospel was not yet published, or barely published, when Clement of Rome wrote his Epistle to the Corinthians. Neither, considering its almost esoteric character and the slow rate at which such a work would travel at first, should we be very much surprised if it was not in the hands of Barnabas (probably in Alexandria) and Hermas (at Rome). In no case indeed could the silence of these two writers be of much moment, as in the Epistle of Barnabas the allusions to the New Testament literature are extremely few and slight, while in the Shepherd of Hermas there are no clear and certain references either to the Old Testament or the New Testament at all.
And yet there is a lively controversy round these two names as to whether or not they contain evidence for the fourth Gospel, and that they do is maintained not only by apologists, but also by writers of quite unquestionable impartiality like Dr. Keim. Dr. Keim, it will be remembered, argues against the Johannean authorship of the Gospel, and yet on this particular point he seems to be almost an advocate for the side to which he is opposed.
'Volkmar,' he says [Endnote 270:1], 'has recently spoken of Barnabas as undeniably ignorant of the Logos-Gospel, and explained the early date assigned to his Epistle by Ewald and Weizsäcker and now also by Riggenbach as due to their perplexity at finding in it no trace of St. John. There is room for another opinion. However much it may be shown that Barnabas gives neither an incident nor a single sentence from the Gospel, that he is unacquainted with the conception of the Logos, that expressions like 'water and blood,' or the Old Testament types of Christ, and especially the serpent reared in the wilderness as an object of faith, are employed by him independently—for all this the deeper order of conceptions in the Epistle coincides in the gross or in detail so repeatedly with the Gospel that science must either assume a connection between them, or, if it leaves the problem unsolved, renounces its own calling. "The Son of God" was to be manifested in the flesh, manifested through suffering, to go to his glory through death and the Cross, to bring life and the immanent presence of the Godhead, such is here and there the leading idea. Existing before the foundation of the world, the Lord of the world, the sender of the prophets, the object of their prophecies, beheld even by Abraham, in the person of Moses himself typified as the only centre of Israel's hopes, and in so far already revealed and glorified in type before his incarnation, he was at last to appear, to dwell among us, to be seen, not as son of David but as Son of God, in the garment of the flesh, by those who could not even endure the light of this world's sun. So did he come; nay, so did he die to fulfil the promise, in the very act of his apparent defeat to dispense purification, pardon, life, to destroy death, to overcome the devil, to show forth the Resurrection, and with the Resurrection his right to future judgment; at the same time, it is true, to fill up the measure of the sins of Israel, whom he had loved exceedingly and for whom he had done such great wonders and signs, and to prepare for himself again a new people who should keep his commandments, his new law. The mission that his Father gave him he has accomplished, of his own free will and for our sake—the true explanation of his death—did he suffer. "The Jews" have not hoped upon him, clearly as the typical design of the Old Testament and Moses himself pointed to him, and, in opposition to the spiritual teaching of Moses, they have been seduced into the carnal and sensual by the devil; they have set their trust and their hopes, not upon God, but upon the fleshly circumcision and upon the visible house of God, worshipping the Lord in the temple almost like the heathen. But the Christian raises himself above the flesh and its lusts, which disturb the faculties of knowledge as well as those of will, to the Spirit and the spiritual service of God, above the ways of darkness to the ways of light; he presses on to faith, and with faith to perfect knowledge, as one born again, who is full of the Spirit of God, in whom God dwells and prophesies, interpreting past and future without being seen or heard; as taught of God and fulfilling the commandments of the new law of the Lord, a lover of the brethren, and in himself the child of peace, of joy, and of love. For this class of ideas there is no analogy in St. Paul, or even in the Epistle to the Hebrews, but only in this Gospel, much as the connection has hitherto been overlooked. Indeed, though it may still in places be questioned on which side the relation of dependence lies (it might be thought that Barnabas supplied the ideas, John the application of them, and the conception of the Logos crowning all), in any case the Gospel appeared at a date near to that of the Epistle of Barnabas. With more reason may it be said that it is not until we come to the Epistle of Barnabas that we find stiff scholastic theory a more predominant typology, an artificialised view of Judaism; besides the points of view always appear as something received and not originated—water and blood, new law, new people—and in the solemn manifestation of the Son of God immediately after the selection of the Apostles, in the great but fruitless exhibition of miracle and love for Israel, there is evidently allusion to history, that is, to John ii and xii.'
'The Epistle of Barnabas,' Dr. Keim adds, 'after the lucid demonstration of Volkmar—in spite of Hilgenfeld and Weizäcker, and now also of Riggenbach—was undoubtedly written at the time of the rebuilding of the temple under the Emperor Hadrian, about the year 120 A.D. (according to Volkmar, at the earliest, 118-119), at latest 130.'
It is not to be expected that this full and able statement should carry conviction to every reader. And yet I believe that it has some solid foundation. The single instances are not perhaps such as could be pressed very far, but they derive a certain weight when taken together and as parts of a wider circle of ideas. The application of the type of the brazen serpent to Jesus in c. xii. may have been suggested by John iii. 14 sqq., but we cannot say that it was so with certainty. The same application is made by Justin in a place where there is perhaps less reason to assume a connection with the fourth Gospel; and we know that types and prophecies were eagerly sought out by the early Christians, and were soon collected in a kind of common stock from which every one drew at his pleasure. A stronger case, and one that I incline to think of some importance, is supplied by the peculiar combination of 'the water and the cross' in Barn. c. xi; not that here there is a direct and immediate, but more probably a mediate, connection with the fourth Gospel. The phrase [Greek: ho uios tou theou] is not peculiar to, though it is more frequent in, and to some degree characteristic of, the Gospel and First Epistle of St. John. [Greek: Phanerousthai] may be claimed more decidedly, especially by comparison with the other Gospels, though it occurs with similar reference to the Incarnation in the later Pauline Epistles. [Greek: 'Elthein en sarki] is again rightly classed as a Johannean phrase, though the exact counterpart is found rather in the Epistles than the Gospel. The doctrine of pre-existence is certainly taught in such passages as the application of the text, 'Let us make man in our image,' which is said to have been addressed to the Son 'from the foundation of the world' (c. v). Generally I think it may be said that the doctrine of the Incarnation, the typology, and the use of the Old Testament prophecies, approximate, most distinctly to the Johannean type, though under the latter heads there is of course much debased exaggeration. The soteriology we might be perhaps tempted to connect rather on the one hand with the Epistle to the Hebrews, and on the other with those of St. Paul. There may be something of an echo of the fourth Gospel in the allusion—to the unbelief and carnalised religion of the Jews. But the whole question of the speculative affinities of a writing like this requires subtle and delicate handling, and should be rather a subject for special treatment than an episode in an enquiry like the present. The opinion of Dr. Keim must be of weight, but on the whole I think it will be safest and fairest to say that, while the round assertion that the author of the Epistle was ignorant of our Gospel is not justified, the positive evidence that he made use of it is not sufficiently clear to be pressed controversially.

A similar condition of things may be predicated of the Shepherd of Hermas, though with a more decided leaning to the negative side. Here again Dr. Keim [Endnote 273:1], as well as Canon Westcott [Endnote 273:2], thinks that we can trace an acquaintance with the Gospel, but the indications are too general and uncertain to be relied upon. The imagery of the shepherd and the flock, as perhaps of the tower and the gate, may, be as well taken from the scenes of the Roman Campagna as from any previous writing. The keeping of the commandments is a commonplace of Christianity, not to say of religion. And the Divine immanence in the soul is conceived rather in the spirit of the elder Gospels than of the fourth.
There is a nearer approach perhaps in the identification of 'the gate' with the 'Son of God,' and in the explanation with which it is accompanied. 'The rock is old because the Son of God is older than the whole of His creation; so that He was assessor to His Father in the creation of the world; the gate is new, because He was made manifest at the consummation of the last days, and they who are to be saved enter by it into the kingdom of God' (Sim. ix. 12). Here too we have the doctrine of pre-existence; and considering the juxtaposition of these three points, the pre- existence, the gate (which is the only access to the Lord), the identification of the gate with the incarnation of Jesus, we may say perhaps a possible reference to the fourth Gospel; probable it might be somewhat too much to call it. We must leave the reader to form his own estimate.
