The Gospels tell that he and his brother John were mending nets on the shore of the Sea of Galilee, when Christ said: “Follow me, and I will make you fishers of men.” Jacob immediately left the boat and his father to follow Christ.
Jacob was a member of the narrow circle of three disciples who witnessed the most mysterious moments of Jesus’ life. Because of his zeal and strength of faith, he, together with his brother, received from Jesus the nickname “Woanerges”, that is, “sons of thunder.” After the Ascension of Christ, the Apostle James preached the Gospel in different countries – according to traditions, in Judea, Samaria and even in Spain. He is credited with founding the first Christian communities on the Iberian Peninsula. Returning to Jerusalem, he was persecuted.
