Luke's unique perspective on Jesus can be seen in the six miracles and eighteen parables not found in the other gospels. Luke's is the gospel of the poor and of social justice. He is the one who tells the story of Lazarus and the Rich Man who ignored him. Luke is the one who uses "Blessed are the poor" instead of "Blessed are the poor in spirit" in the beatitudes. Only in Luke's gospel do we hear Mary 's Magnificat where she proclaims that God "has brought down the powerful from their thrones, and lifted up the lowly; he has filled the hungry with good things, and sent the rich away empty" (Luke 1:52-53).
Luke also has a special connection with the women in Jesus' life, especially Mary. It is only in Luke's gospel that we hear the story of the Annunciation, Mary's visit to Elizabeth including the Magnificat, the Presentation, and the story of Jesus' disappearance in Jerusalem. It is Luke that we have to thank for the Scriptural parts of the Hail Mary: "Hail Mary full of grace" spoken at the Annunciation and "Blessed are you and blessed is the fruit of your womb Jesus" spoken by her cousin Elizabeth.
Forgiveness and God's mercy to sinners is also of first importance to Luke. Only in Luke do we hear the story of the Prodigal Son welcomed back by the overjoyed father. Only in Luke do we hear the story of the forgiven woman disrupting the feast by washing Jesus' feet with her tears. Throughout Luke's gospel, Jesus takes the side of the sinner who wants to return to God's mercy.
Reading Luke's gospel gives a good idea of his character as one who loved the poor, who wanted the door to God's kingdom opened to all, who respected women, and who saw hope in God's mercy for everyone.
The reports of Luke's life after Paul's death are conflicting. Some early writers claim he was martyred, others say he lived a long life. Some say he preached in Greece, others in Gaul. The earliest tradition we have says that he died at 84 Boeotia after settling in Greece to write his Gospel.
A tradition that Luke was a painter seems to have no basis in fact. Several images of Mary appeared in later centuries claiming him as a painter but these claims were proved false. Because of this tradition, however, he is considered a patron of painters of pictures and is often portrayed as painting pictures of Mary.
He is often shown with an ox or a calf because these are the symbols of sacrifice -- the sacrifice Jesus made for all the world.
Luke is the patron of physicians and surgeons.
