Here are some prayers to the Holy Spirit, taken from the Prayer Book of the Library of Catholic Devotion. These books were published in 1959 and aren’t currently in print, but if you can find an old copy I would encourage it. I have loved this prayer book for many years, and my family especially likes to use the prayers for the dying found in this book.
For the Grace of the Holy Ghost
Come, Holy Ghost, Sanctifier all powerful, God of love, Thou Who didst fill the Virgin Mary with grace, Thou Who didst wonderfully transform the hearts of the Apostles, Thou Who didst endow all Thy martyrs with a miraculous heroism, come and sanctify us. Illumine our minds, strengthen our wills, purify our consciences, rectify our judgments, set our hearts on fire, and preserve us from the misfortune of resisting Thine inspirations. Amen.(Indulgence of 500 days)
For a Pure Heart
(Roman Missal Indulgence of 500 days)
Consecration to the holy ghost
O Holy Spirit, divine Spirit of light and love, I consecrate to Thee my understanding, my heart and my will, my whole being for time and for eternity. May my understanding be always submissive to Thy heavenly inspirations and to the teachings of the holy Catholic Church, of which Thou art the infallible Guide; may my heart be ever inflamed with love of God and of my neighbor; may my will be ever conformed to the divine will, and may my whole life be a faithful imitation of the life and virtues of our Lord and Savior Jesus Christ, to Whom with the Father and Thee be honor and glory forever. Amen.
(Indulgence of 500 days)
O Holy Spirit, Spirit of truth, come into our hearts; shed the brightness of Thy light upon the nations, that they may please Thee in unity of faith.
For the Grace of God
O Thou plenteous source of every good and perfect gift! bestow abroad the consoling light of Thy seven-fold grace over our hearts! Yea, Spirit of love and gentleness: most humbly we implore Thine assistance! Thou knowest our faults, our failings, our necessities, the dullness of our understanding, the waywardness of our affections, the perverseness of our will. When, therefore, we neglect to practice what we know, visit us, we beseech Thee, with Thy grace; enlighten, God, our minds, rectify our desires, correct our wanderings, and pardon our omissions, so that, by Thy guidance, we may be preserved from making shipwreck of faith, and keep a good conscience, and so, at length, we may be landed in the safe haven of eternal peace. Through Jesus Christ, our Lord. Amen.
For the Help of the Holy Ghost
We beseech Thee, O Holy Spirit, descend with Thy light and consolation into our souls; enlighten our understanding, and consecrate the hearts which Thou has sanctified as Thy temples. O Holy Ghost, come and bring us God’s blessing and peace; console us and all the afflicted; encourage and strengthen the weak; instruct and support the wavering; arouse sinners to penance, and enkindle in their cold hearts the fire of divine love and filial confidence in Thee, that all men, in peace and joy, may thankfully praise and adore Thee, together with the Father and the Son, one God, world without end. Amen.
