From the Treasury of Daily Prayer:

St. Philip is mentioned in the lists of the apostles (Matthew 10:3; Mark 3:18; Luke 6:14; Acts 1:13), but only in John’s Gospel is more told about him. Philip was from Bethsaida in Galilee and one of the first disciples called after Peter and Andrew. Philip also was instrumental in bringing Nathanael to Jesus (John 1:43-51). It was to Philip that Jesus posed the question about where to buy bread to feed five thousand men (John 6:5). During Holy Week, Philip with Andrew brought some inquiring Greeks to Jesus (John 12:20-22). And on Maundy Thursday evening, Philip asked Jesus to show the Father to him and to the rest of the disciples (John 14:8). According to tradition, Philip went to labor in Phrygia and was buried there.

St. James was a son of Alphaeus and was also called “the Younger” (to distinguish him from James, the son of Zebedee, “the Elder,” whose festival day is July 25). His mother, Mary, was one of the faithful women who stood at the cross of Jesus (Matthew 27:56; Mark 15:40). James is mentioned in the same apostolic lists as Philip, but there is no other mention of him in the New Testament. There is also no information regarding his field of labor or the circumstances of his death, except that he may have been martyred by being sawed in two.
