"COME HOLY SPIRIT" Pentecost Sunday is on Sunday, June 4th. The novena begins on the Friday the 26th. of May (after Ascension Thursday even if the solemnity is moved to Sunday) We encourage everyone to pray the Novena to the Holy Spirit even if you missed the first few days.. - The novena in honor of the Holy Spirit is the oldest of all novenas since it was first made at the direction of Our Lord Himself when He sent His apostles back to Jerusalem to await the coming of the Holy Spirit on the first Pentecost. It is still the only novena officially prescribed by the Church. Addressed to the Third Person of the Blessed Trinity, it is a powerful plea for the light and strength and love so sorely needed by every Christian
