The Pentecost Novena is the first of all novenas, nine days of prayer. After Jesus' Ascension into heaven, He commanded His disciples to come together in the upper room to devote themselves to constant prayer (Acts 1:14). They prayed for nine days before receiving the Holy Spirit on Pentecost.
On May 4, 1897, Pope Leo XIII proclaimed: "We decree and command that throughout the whole Catholic Church, this year and in every subsequent year, a novena shall take place before Pentecost, in all parish churches." It has been reported that Pope Leo XIII was inspired to mandate the Pentecost novena because of a letter from a housewife in Italy. Pope John Paul II has reiterated Pope Leo XIII's command for a worldwide Pentecost novena, although the novena can be prayed at any time — not only before Pentecost.
Try to go to Mass daily throughout the novena. Go to Confession during the novena. Make visits to church to adore the eucharistic Jesus throughout the novena. Pray the novena daily, beginning May 31st.
O Lord Jesus Christ, Who, before ascending into heaven, promised to send the Holy Spirit to finish Your work in the souls of Your Apostles and Disciples, grant to give the same Holy Spirit to me that He may perfect in my soul, the work of Your grace and Your love.
Grant me the Spirit of Wisdom that I may be detached from the perishable things of this world and aspire only after the things that are eternal; the Spirit of Understanding to enlighten my mind with the light of Your divine truth; the Spirit of Counsel that I may always choose the surest way of pleasing God and gaining heaven; the Spirit of Fortitude that I may bear my cross with You and that I may overcome with courage all the obstacles that oppose my salvation; the Spirit of Knowledge that I may know God and know myself and grow perfect in the knowledge of the Saints; the Spirit of Piety that I may find the service of God sweet and desirable; and the Spirit of Holy Fear that I may be filled with a loving reverence towards God and may dread in any way to displease Him. Mark me, dear Lord, with the sign of Your true disciples and animate me in all things with Your Spirit. Amen.
