O God, who by the Immaculate Conception of the Blessed Virgin Mary, did prepare a worthy dwelling place for Your Son, we beseech You that, as by the foreseen death of this, Your Son, You did preserve Her from all stain, so too You would permit us, purified through Her intercession, to come unto You. Through the same Lord Jesus Christ, Your Son, who lives and reigns with You in the unity of the Holy Spirit, God, world without end. Amen.
