Over at Vultus Christi, you can find a series of Chapter Talks on the Rule of Saint Benedict. Today’s commentary concludes with the story of a mighty prayer of deliverance given by the Blessed Virgin Mary to a French priest of the nineteenth century, Bl. Louis-Edoard Cestac. Here it is:
August Queen of Heaven, sovereign Mistress of the Angels, thou who from the beginning hast received from God the power and the mission to crush the head of Satan, we humbly beseech thee to send thy holy legions, that under thy command and by thy power they may pursue the evil spirits, encounter them on every side, resist their bold attacks, and drive them hence into eternal woe.
Who is like unto God?
O good and tender Mother, thou willest always to be our love and our hope.
O Mother of God, send thy holy Angels to defend us and drive far from us the cruel enemy.
Holy Angels and Archangels, defend us and keep us. Amen.
Go read the whole thing. In fact, all of the commentaries are edifying; read them all.
