Prayer for the Rooting Out of Heresies

O MOST pitiful Lord Jesus Christ, true Light for the enlightening of the Gentiles, we beseech thy clemency that thou wouldst regard the destruction of so many souls, which through the cunning of the ancient serpent and the wiles of heretics have been plunged in deep and utter darkness. Can it be, O most merciful Jesus, that thou shouldst suffer those helpless souls, which thou hast redeemed with thy own precious Blood, to be deceived by the devil and subject to his sway? Canst thou permit so many wretched souls to be daily thrust down to hell for lack of the true faith? Remember, O Christ Jesus, how many toilsome journeys thou didst undertake for their salvation, and what grievous stripes and wounds thou didst receive for their redemption. We beseech thee, therefore, by the virtue of thy most bitter Passion and death, that thou wouldst vouchsafe to crush and extinguish those accursed heresies, and to convert the hearts of all hardened heretics to thy true faith. Amen.
