St 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 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. [Source: Catholic Online]
Happy Saint’s Day, Luke.
