Revelation: An Overview
Most scholars agree that the Book of Revelation is not pseudonymous, though they debate which John authored it: John the Apostle, John the Elder, an unknown John, John Mark, or John the Baptist. However, the latter two have not gained serious support, leaving the former three as potential authors of the Book. John identifies himself three times as the author of the Letter (1:1, 4, 9; 22:8), and throughout the Greek Book, the syntax and idiosyncrasies "that reflect Semitic syntax," demonstrate the author's native tongue of Galilean Hebrew.
