Yet it is said it cannot be by the same writer as the Fourth Gospel because the _Greek_ is so different, that of the Revelation being very abrupt, with numerous faults of grammar, while the Gospel is in good Greek. Therefore it is urged that a Galilean fisherman like St. John, though he might have been sufficiently educated to have written the former, as his father was well off and kept servants, and he himself was a friend of the High Priest,[235] could scarcely have written the latter. Various explanations have been given of this. Perhaps the best is that the Revelation was written by St. John himself, since he is not likely to have had friends in Patmos; and that when writing the Gospel he had the assistance of a Greek disciple. [Footnote 235: Mark 1. 20; John 18. 15.] On the other side, it must be remembered that though the two books are different in language, they are the same in their _teaching_; for the great doctrine of the Fourth Gospel, that of the Divinity of Christ, is asserted almost as plainly in the Revelation. And even the striking expression that Christ is the _Logos_, or _Word_, occurs in both books, though it is not found elsewhere in the New Testament, except in one of St. John's Epistles.[236] And the same may be said of another striking expression, that Christ is the _Lamb_, which also occurs in the Gospel and Revelation, though not elsewhere in the New Testament.[237] This similarity in doctrine is indeed so marked that it strongly suggests the same authorship; and if so, it makes it practically certain that the Fourth Gospel was written by St. John. [Footnote 236: John 1. 1; 1 John 1. 1; Rev. 19. 13.] [Footnote 237: John 1. 29, 36; Rev. 6. 1; 14. 1.] On the whole, then, these objections are not serious; while, as already shown, the Fourth Gospel has very strong internal marks of genuineness. And when we combine these with the equally strong external testimony, it forces us to conclude that St. John was the author. This Gospel, then, like the other three, must be considered _genuine_; indeed, the evidence in favour of them all is overwhelming. CHAPTER XVI. THAT THE GOSPELS ARE GENUINE FROM THE EVIDENCE OF THE ACTS. Importance of the Acts, as it is by the writer of the Third Gospel. (_A._) ITS ACCURACY. Three examples of this: (1.) The titles of different rulers. (2.) The riot at Ephesus. (3.) The agreement with St. Paul's Epistles. (_B._) ITS AUTHORSHIP. The writer was a companion of St. Paul, and a medical man; so probably St. Luke. (_C._) ITS DATE. There are strong reasons for fixing this at the close of St. Paul's imprisonment at Rome, about A.D. 60; and this points to an earlier date for the first three Gospels.
