John the Evangelist (? - c. 110; יוחנן "The LORD is merciful", Standard Hebrew Yoḥanan, Tiberian Hebrew Yôḥānān) is presumed to be the author of the Gospel of John. Tradition has identified him with John the Apostle, although numerous modern scholars dispute that they are the same person (see authorship of the Johannine works). Either way, the author of this Gospel is also presumed to be the author of other books in the New Testament: 1 John, 2 John, 3 John, and the Book of Revelation. There are also schools of thought which attribute some of these five works (always including The Gospel of John) to John the Apostle and others (usually including the 2nd and 3rd epistles) to another John. Collectively, these books are known as Johannine literature, and there is internal textual evidence that they were authored by the same person (see textual criticism).
