Why More Hail Marys than Our Fathers in the Rosary

The words of the first part of the Hail Mary are words addressed to her by the angel Gabriel and her relative Elizabeth. The second part is merely a request for the mother of God to pray for us.

But most important of all: the whole point (the context) of the Hail Mary is not Mary but the incarnation of Jesus. Without the incarnation, we would have no Our Father. If Jesus had not taken flesh in her womb, we would necver have heard of her. So whenever we pray the Hail Mary, we are professing our faith in Jesus, the Word made flesh. As she said to Elizabeth, her soul magnifies the Lord; everything about her speaks of God.
