The author of the Book of Revelation identifies himself only as "John".[7] Traditionally, this was often believed to be the same person as John the Apostle (John, son of Zebedee), one of the apostles of Jesus, to whom the Gospel of John was also attributed.[7] The early-2nd-century writer, Justin Martyr, was the first to equate the author of Revelation with John the Evangelist.[8]
Other early Christian writers, such as Dionysius of Alexandria and Eusebius of Caesarea, noting the differences in language and theological outlook between this work and the Gospel,[9] discounted this possibility, and argued for the exclusion of the Book of Revelation from the canon as a result.[10] The early Christian writer Papias appeared in his writings to distinguish between John the Evangelist and John the Elder,[11] and many biblical scholars now contend that the latter was the author of Revelation.[12][13][14]
