Saint John the Evangelist (±1 - ±100 AD) is the conventional name for the author of the Gospel of John. Traditionally he has been identified with the author of all the Johannine works in the New Testament – the three Epistles of John and the Book of Revelation, written by a John of Patmos – as well as with John the Apostle and the Beloved Disciple[1] mentioned in the Book of John. However, at least some of these connections have been debated since about 200 AD.
