St. John the Apostle (c. 6 AD – c. 100 AD) or Saint John the Beloved was one of the Twelve Apostles of Jesus. Generally listed as the youngest apostle, he was the son of Zebedee and Salome. His brother James was another of the Twelve Apostles. The Church Fathers identify him as John the Evangelist, John of Patmos, John the Elder, and the Beloved Disciple, and testify that he outlived the remaining apostles and was the only one to die of natural causes.
St. John the Apostle is held to be the author of the Gospel of John, as well as several other books of the New Testament.
