According to St. Bonaventure, all the angels in heaven unceasingly call out to her: "Holy, holy, holy Mary, Virgin Mother of God." They greet her countless times each day with the angelic greeting, "Hail, Mary", while prostrating themselves before her, begging her as a favour to honour them with one of her requests. According to St. Augustine, even St. Michael, though prince of all the heavenly court, is the most eager of all the angels to honour her and lead others to honour her. At all times he awaits the privilege of going at her word to the aid of one of her servants.
