“Arise then, O invincible prince, bring help against the attacks of the lost spirits to the people of God, and bring them the victory.
　The Church venerates thee as protector and patron; in thee holy Church glories as her defense against the malicious powers of this world and of hell; to thee has God entrusted the souls of men to be established in heavenly beatitude.
　Oh, pray to the God of peace that He may put Satan under our feet, so far conquered that he may no longer be able to hold men in captivity and harm the Church. Offer our prayers in the sight of the Most High, so that they may quickly conciliate the mercies of the Lord; and beating down the dragon, the ancient serpent, who is the devil and Satan, do thou again make him captive in the abyss, that he may no longer seduce the nations. Amen.”  Pope Leo XIII, Leonine Prayers
