Saint John was one of the Twelve, part of Jesus’ inner circle, among the few that witnessed the Transfiguration, the raising of Jarius’ Daughter, and the Agony in the garden at Gethsemane. He and his brother James were the sons of Zebedee and Salome. When Jesus called them, they left their father mending nets and followed him. Jesus called the brothers “Boanerges,” meaning “sons of thunder” — they were passionate in their faith and Jesus had to rebuke them for their fiery zeal on more than one occasion. John, the younger brother, possibly the youngest disciple, was the only one present at Jesus’ death.
Saint John the Apostle is traditionally thought to be the author of the fifth Gospel, the three Epistles of John, and the Book of Revelation. However, there has been some debate among scholars from antiquity to the present. Tradition also gives him the title Beloved Disciple and John’s Gospel sees him seated next to Jesus at the last supper and the one to whom Jesus gives the care of Mary at the crucifixion.
Although Church tradition says that John survived the other disciples, living a long life, much of it is steeped in myth and legend. Some say he retired to Ephesus after the crucifixion with Mary and remained there until he died. But in other traditions he is more active. For a time he remained in Jerusalem with the other disciples, then founded churches in Asia Minor. In a legend of his persecution, during the reign of the Emperor Domitian, John is taken to Rome and thrown into a cauldron of boiling oil but preserved from death. He is then exiled to the island of Patmos where the Book of Revelation was written.
Most accounts agree that after his exile and the Assumption of Mary he returned to Ephesus where he died sometime after 98, during the reign of the Emperor Trajan.
