THE APOSTLE JOHN
According to church tradition, John is the author of several New Testament writings: the Gospel of John, the three Epistles of John and the Book of Revelation. However, there is disagreement among modern scholars as to the authorship of the Book of Revelation. In this debate, there is a distinction drawn between the Apostle John and the John of Patmos, who is the author of Revelation.
John, also known as the beloved disciple, was a fisherman and a disciple of John the Baptist before joining the ministry of Jesus of Nazareth. The New Testament portrays him as a favorite of Christ, the only disciple who stayed with him during the crucifixion, and the one who promised to honor Christ's request to care for his mother Mary.
John was the only disciple to survive into old age, dying of natural causes at the age of 94. He is the patron saint of writers and his feast day is December 27.
