The angels in heaven, according to St. Bonaventure, never stop calling to her, "Holy, holy, holy Mary, Virgin Mother of God!" A million times a day they give her the angelic greeting, "Hail Mary!" They prostrate themselves before her. They beg her to honor them with her commands. St. Michael, the prince of the heavenly court, is the most eager to pay her homage, St. Augustine says, and to run her errands.
