John the Apostle in Wikipedia

John the Apostle (Ancient Greek: Ἰωάννης) (c. 6 - c. 100) was one of the Twelve Apostles of Jesus. He was the son of Zebedee and Salome, and brother of James also the son of Zebedee, another of the Twelve Apostles. Christian tradition holds he was the last surviving of the Twelve Apostles, the only one to die a natural death and died around the age of 94. Christian tradition identifies him as the author of several New Testament works: the Gospel of John, the Epistles of John, and the Book of Revelation. Some modern scholars believe that John the Apostle, John the Evangelist, and John of Patmos were three separate individuals.[2] Certain lines of evidence suggest that John of Patmos wrote only Revelation, neither the Gospel of John nor the Epistles of John. For one, the author of Revelation identifies himself as "John" several times, but the author of the Gospel of John never identifies himself directly. Roman Catholic scholars state that "vocabulary, grammar, and style make it doubtful that the book could have been put into its present form by the same person(s) responsible for the fourth gospel."...
