The holy, glorious and all-laudable '''Apostle and Evangelist John''' is also known as '''John the Theologian'''. He was one of the original twelve [[Apostles]], and wrote the [[Gospel of John|Gospel]] bearing his name; three canonical letters: [[I John]], [[II John]], and [[III John]]; and the [[Book of Revelation]]. His [[feast day]] is celebrated on [[May 8]], that of the twelve apostles on [[June 30]], and his repose on [[September 26]].

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 mystical supper, where St. John leans on Jesus.
