From the Treasury of Daily Prayer:

St. Bartholomew (or Nathanael, as he is called in St. John’s Gospel) was one of the first of Jesus’ twelve disciples. His home was in the town of Cana, in Galilee (John 21:2), where Jesus performed His first miracle. He was invited to become one of the Twelve by Philip, who told him that they had found the Messiah in the person of Jesus of Nazareth (John 1:45). Bartholomew’s initial hesitation to believe, because of Jesus’ Nazareth background, was quickly replaced by a clear, unequivocal declaration of faith, “You are the Son of God! You are the King of Israel!” (John 1:49). He was present with the other disciples (John 21:1-13) when they were privileged to see and converse and eat with their risen Lord and Savior. According to some Early Church Fathers, Bartholomew brought the Gospel to Armenia, where he was martyred by being flayed alive.
