In his own Gospel account, he refers to himself as "the disciple whom [[Jesus]] loved" rather than use his name. He was the youngest of the twelve apostles, and especially close to the Lord. This closeness is often portrayed in [[icon]]s of the [[Last Supper icon|mystical supper]], where St. John leans on Jesus.
He was present for the [[Transfiguration]] of Christ with [[Apostle Peter|Peter]] and his brother James.
St. John was exiled to the island of Patmos by Emperor Domitian around 90-95 A.D., and it was there that he received and wrote the Book of Revelation.
