The difference in style between the Revelation and the gospel of John is due to the fact that the Revelation was written during John’s exile in Patmos, under Nero, in 67 or 68, soon after John had left Palestine and had taken up his residence at Ephesus. He had hitherto spoken Aramæan, and Greek was comparatively unfamiliar to him. The gospel was written thirty years after, probably about 97, when Greek had become to him like a mother tongue. See Lightfoot on Galatians, 343, 347; _per contra_, see Milligan, Revelation of St. John. Phrases and ideas which indicate a common authorship of the Revelation and the gospel are the following: “the Lamb of God,” “the Word of God,” “the True” as an epithet applied to Christ, “the Jews” as enemies of God, “manna,” “him whom they pierced”; see Elliott, Horæ Apocalypticæ, 1:4, 5. In the fourth gospel we have ἀμνός, in Apoc. ἀρνίον, perhaps better to distinguish “the Lamb” from the diminutive τὸ θηρίον, “the beast.” Common to both Gospel and Rev. are ποιεῖν, “to do” [the truth]; περιπατεῖν, of moral conduct; ἀληθινός, “genuine”; διψᾷν, πεινᾷν, of the higher wants of the soul; σκηνοῦν ἐν, ποιμαίνειν, ὁδηγεῖν; also “overcome,” “testimony,” “Bridegroom,” “Shepherd,” “Water of life.” In the Revelation there are grammatical solecisms: nominative for genitive, 1:4—ἀπὸ ὁ ὤν; nominative for accusative, 7:9—εἶδον ... ὄχλος πολύς; accusative for nominative, 20:2—τὸν δράκοντα ὁ ὄφις. Similarly we have in _Rom. 12:5_—τὸ δὲ καθ᾽ εἶς instead of τὸ δὲ καθ᾽ ἕνα, where κατὰ has lost its regimen—a frequent solecism in later Greek writers; see Godet on John, 1:269, 270. Emerson reminded Jones Very that the Holy Ghost surely writes good grammar. The Apocalypse seems to show that Emerson was wrong.
