Consider the role of women in Luke's Gospel.
Luke gives women a much greater role than do the other Gospels. He discusses the mother of John the Baptist, whose name is Elizabeth, more than the others, and his is the only gospel in which the Annunciation, the event where the angel Gabriel announces the forthcoming immaculate conception and birth of Christ to Mary:
And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women...And the angel said unto her, Fear not, Mary: for thou hast found favour with God. And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name Jesus. He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
This is, of course, a highly significant event in the Christian faith, one which serves to emphasize the holy nature of Mary, but it is only mentioned in Luke. In Matthew, the Annunciation is given to Joseph, Mary's husband, after Mary is already visibly pregnant. Additionally, in Luke, the roles of Mary Magdalene, Martha, and Mary of Bethany among the disciples of Jesus are more prominent. Mary Magdalene, for example, is not mentioned until after the cruxifixion in the other gospels, while Luke discusses the circumstances under which she began to follow and support him. It should be noted, however, that the other gospels mention her by name as being present at the cruxifixion, and that in Matthew, Mark, and John, she is the first to witness the resurrected Jesus.
