Many modern scholars consider the birth narratives unhistorical because they are laced with theology and present two different accounts.[147][148] For instance, they point to Matthew's account of the appearance of an angel to Joseph in a dream; the wise men from the East; the massacre of the innocents; and the flight to Egypt, which do not appear in Luke, which instead describes the appearance of an angel to Mary; the Roman census; the birth in a manger; and the choir of angels.[149]
