The Rosary is both meditation and supplication. Insistent prayer to the Mother of God is based on confidence that her maternal intercession can obtain all things from the heart of her Son. She is "all-powerful by grace," to use the bold expression, which needs to be properly understood, of Blessed Bartolo Longo in his Supplication to Our Lady. This is a conviction which, beginning with the Gospel, has grown ever more firm in the experience of the Christian people. The supreme poet Dante expresses it marvelously in the lines sung by Saint Bernard: "Lady, thou art so great and so powerful, that whoever desires grace yet does not turn to thee, would have his desire fly without wings." When in the Rosary we plead with Mary, the sanctuary of the Holy Spirit (cf. Lk 1:35), she intercedes for us before the Father who filled her with grace, and before the Son born of her womb, praying with us and for us.
