Ave Maria Meditations
Oh glorious Queen of heaven and earth, Virgin Most Powerful, thou who hast the power to crush the head of the ancient serpent with thy heel, come and exercise this power flowing from the grace of thine Immaculate Conception. Shield us under the mantle of thy purity and love, draw us into the sweet abode of thy heart and annihilate and render impotent the forces bent on destroying us.
Come most sovereign mistress of the holy angels and mistress of the most holy rosary, thou who from the very beginning hast received from God the power and the mission to crush the head of satan. Send forth thy holy legions, we humbly beseech thee, that under thy command and by the thy power they may pursue the evil spirits, counter them on every side, resist their bold attacks and drive them far from us, harming no one on the way, binding them to the foot of the cross to be judged and sentenced by Jesus Christ thy Son, and to be disposed of by Him as He wills.
