Pope Leo XIII " We ought to pray and invoke the Holy Spirit, for each of us greatly needs his protection and His help. The more a man is deficient in wisdom, weak in strength, borne down with trouble, prone to sin, so ought he the more fly to Him who is the never ceasing Fount of Light, Strength, Consolation and Holiness."
The novena in honor of the Holy Ghost 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 Ghost on the first Pentecost. It is still the only novena 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. To encourage devotion to the Holy Spirit, the Church has enriched this novena with the following indulgences.
The faithful who devoutly assist at the public novena in honor of the Holy Ghost immediately preceeding the Feast of Pentecost may gain:
An indulgence of 10 years on any day of the novena;
A plenary indulgence if they take part in at least five of the exercises, and moreover,
Go to confession, and receive Holy Communion.
