This James is the brother of John the Evangelist. The two were called by Jesus as they worked with their father in a fishing boat on the Sea of Galilee. James was one of the favored three who had the privilege of witnessing the Transfiguration, the raising to life of the daughter of Jairus, and the agony in Gethsemani.
