O Mary, powerful Virgin, thou art the mighty and glorious protector of the Church; thou art the marvelous help of Christians; thou art terrible as an army in battle array; thou alone hast destroyed every heresy in the whole world. In the midst of our anguish, our struggles, and our distress, defend us from the power of the enemy and at the hour of our death, receive our souls in paradise. Amen.
(St. John Bosco)
