The Word is made flesh: Jesus is born in Bethlehem.
The story
In the fulness of time the angel Gabriel announces to Mary that she will bear the Son of God. Jesus is born in Bethlehem and laid in a manger. Angels proclaim good tidings of great joy to shepherds, and wise men come from the east to worship Him.
