Catholic Prayer: Novena for Pentecost
This novena prayer, although short is sufficient. It would be better of course to add, if time permits, three Hail Marys or say five times the Our Father, Haily Mary and Glory be to the Father, or to use some of the many well-loved novena prayers from other sources. Remember that prayers must be said with the lips in order to gain the indulgences. For the novenas that precede the movable feasts, it is necessary to begin nine days before the feast occurs.
O Holy Spirit, who descended upon the Apostles and filled them with power and wisdom, watch over me and guide me in all my thoughts and acts. Never let me forget to call on you whenever I need help. Amen.
O Holy Spirit, Spirit of Truth, come into our hearts, shed the brightness of Your light on all nations, that they may be one in faith and pleasing to You.
