Brothers James and John, the sons of Zebedee, were fishermen on Lake Galilee. James was probably the elder, as he is usually named first, they were business partners of Peter (Luke 5:1-11), mention of hired servants (Mark 1:20) suggests a modest family business. They lived in or near Capernaum (Mark 1:21) and along with Peter and Andrew (Matthew 4:18-22; Mark 1:14-20) were among the first disciples to be recruited, by Jesus.

Nicknamed, 'The Sons of Thunder' by Jesus (Mark 3:17), it was James and John who asked Jesus whether he wanted them, in the tradition of Elijah, to call down fire on the Samaritan village which declined to receive them (Luke 9:51-56). Together with Peter they formed an inner core among the disciples. They (and Andrew) were present at the healing of Peter’s mother-in-law (Mark 1:29-31). Peter, James and John were the ones present when Jesus raised Jairus’ daughter (Mark 5:37; Luke 8:51) at the transfiguration (Matthew 17:1; Mark 9:2; Luke 9:28), and in the garden of Gethsemane (Matthew 26:37; Mark 14:33). Their mother requested that they be allowed to sit on either side of Jesus in his coming glory (Matthew 20:20-28; Mark 10:35-45;).

John accompanied Peter in making the preparations for the Last Supper (Luke 22:8) and in John’s Gospel, in with a little De javu to their original call (John 21:2)James and John were together with other disciples at the resurrection appearance of Jesus on the shores of Lake Galilee.

James was executed on the orders of Herod Agrippa in the early 40s A.D. (Acts 12:1-3), which indicates his significant leadership role in the early church. John appears on several occasions with Peter: in the upper room (Acts 1:13); in the Temple precincts, leading to their subsequent arrest and release (Acts 3:1-4,31); and in a visit to Samaria, in the wake of Philip (Acts 8:14-25). John was clearly therefore another significant leader of the early church, and was recognized as such by Paul (Galatians 2:9).

We have no further information from the New Testament about either apostle. There is a strong tradition that John eventually went to Ephesus and was a leader of the church there, but that is tied to the question of whether John the apostle is also John the evangelist. They maybe the same man but in case they are not, John the apostle is commemorated with his brother James the Great, and John the evangelist is commemorated separately (27 December).

James came to have an association with Santiago de Compostella in Spain. It is possible his bones were removed there. What is known is that Compostella became a very important place of pilgrimage and of the cult of St James in the late Middle Ages.
