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 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.
How to pray the Novena
Each day the meditation and prayer for the particular day is said, followed by one (1) Our Father, one (1) Hail Mary and seven (7) Glory be to the Fathers, the Act of Consecration and the Prayer for the Seven Gifts. (From Novena's text)
