The Holy Spirit is the source of sanctifying grace, the life of God within our souls. By submitting our will to His, we grow in holiness. This act of consecration expresses our desire to unite ourselves to the Spirit's will.
Act of Consecration to the Holy Spirit
O Holy Spirit,
Divine Spirit of light and love,
I consecrate to Thee my understanding,
heart, and will,
my whole being for time and eternity.
May my understanding be always submissive
to Thy heavenly inspirations,
and to the teaching of the Catholic Church,
of which Thou are 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 Saviour Jesus Christ,
to whom with the Father and Thee
be honour and glory forever. Amen.
