‘The Epistle of Barnabas,’ Dr. Keim adds, ’after the lucid demonstration of Volkmar—in spite of Hilgenfeld and Weizaecker, 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
