Prayer to the Holy Spirit – Pope Pius X, June 5, 1908

O HOLY SPIRIT, divine spirit of light and love, I consecrate to Thee my understanding, heart and will, my whole being for time and for eternity. May my understanding be always submissive to thy heavenly inspirations, and to the teaching of the Catholic Church, of which Thou art the infallible Guide; may my heart be ever inflamed with love of GOD and of my neighbour; 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 SAVIOUR JESUS CHRIST, to whom the FATHER and Thee be honour and glory for ever. Amen.

Pope Saint Pius X (1910), Papacy 1903-1914
