O merciful Lord, incline Thine ears to our prayers, and enlighten our hearts by the grace of Thy Holy Spirit: that we may worthily receive Thy holy Mysteries, and love Thee with an everlasting love. O God, unto whom every heart is open, every desire known, and from whom no secret is hid: cleanse the thoughts of our hearts by the inspiration of Thy Holy Spirit, that we may perfectly love Thee and worthily praise Thee. Inflame, O Lord, our reins and our hearts with the fire of the Holy Ghost: that we may serve Thee with a chaste body, and please Thee with a pure mind. We pray Thee, O Lord, that the Comforter who proceedeth from Thee may illuminate our minds, and lead us, as Thy Son hath promised, into all truth. May the power of Thy Holy Spirit, O Lord, be present with us to cleanse us from all evil and defend us from all adversities. O God, who didst teach the hearts of Thy faithful by the light of Thy Holy Spirit: grant us by the same Spirit to have a right judgment in all things, and evermore to rejoice in His holy comfort. Visit, O Lord, we beseech Thee, and cleanse our consciences, that Thy Son, our Lord Jesus Christ, when He cometh, may find in us a mansion prepared for Himself.
