John

John, son of Zebedee and brother of James, was one of Jesus's closest disciples, often identified as "the disciple whom Jesus loved." Originally a fisherman with a fiery temperament (nicknamed "son of thunder"), John was transformed into an apostle of love through his relationship with Christ. Present at key moments like the Transfiguration and in Gethsemane, John stood faithfully at the cross when other disciples fled, receiving the responsibility to care for Jesus's mother. In his Gospel and three epistles, John emphasized Jesus's deity, the incarnation, and the primacy of love. Later exiled to Patmos, he received the apocalyptic visions recorded in Revelation. Church tradition suggests John was the only apostle to die of natural causes after a long ministry in Ephesus.
