(Jn 19:26-27). John, his brother James, and Peter formed the inner circle in the apostolic group. With Peter and James, he witnessed the Transfiguration, the healing of Peter's mother-in-law, the raising of the daughter of Jairus, and the agony at Gethsemane. Jesus nicknamed the brothers John and James "sons of thunder." John is traditionally regarded as the author of the Fourth Gospel, the three epistles that bear his name, and the Book of Revelation. In connection with Revelation, he is called John "the Divine," and John "the Theologian." After a period of exile on the isle of Patmos under the emperor Domitian, he went to Asia Minor and settled at Ephesus. According to tradition, John wrote Revelation while on the isle of Patmos. He probably died in Ephesus. John is believed to be the only apostle who was not martyred. Some consider him the patron of theologians, writers, and those who produce books. John is commemorated in the Episcopal calendar of the church year on Dec. 27.
