The virgin Mary is engaged to Joseph. They live in Nazareth. Luke gives details of the angel visit and Mary's response. Jesus is uniquely God and man. Mary is seen to be faithful.

Matthew wrote for the Jews. The genealogy of Jesus is traced back to Abraham, the father of the nation. Matthew traces the ancestry through Joseph but Luke through Mary. Ancestry was important to Jews.
