John, often called the “Beloved Disciple,” is the author of the fourth Gospel and the book of Revelation. He was the one of the twelve disciples who remained with Christ, standing in front of the cross. Jesus entrusted his mother to John’s care on the day of the Crucifixion. The best known verse in his gospel is, “For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life,” (John 3:16). According to tradition John left Jerusalem after attending the first council and went to Asia Minor and settled in Ephesus . He was exiled to the island of Patmos where he wrote the Book of Revelation.
