One of my all-time favorite novenas is the novena in honor of the Holy Spirit. It 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.
In preparation for Pentecost Sunday, here are the nine posts (I've posted them here at Raising Little Saints in the past) of this beautiful Novena. Our eldest son just received Confirmation and he will be in charge of heading this prayer devotion for our family.
