Where do we get novenas?

This morning I went to Mass. Until very recently, we would have celebrated the Feast of the Ascension, but in recent years the Feast has been moved from this Thursday to the nearest Sunday. I’m not such a fan of this change since it obscures the origin of the “novena”, the Catholic practice of nine days of prayer for a particular intention.

Novenas are associated with the period of time between the Ascension of Jesus and the coming of the Holy Spirit at Pentecost:

[Jesus said] “But you shall receive power when the Holy Spirit has come upon you; and you shall be my witnesses in Jerusalem and in all Judea and Samar′ia and to the end of the earth.” And when he had said this, as they were looking on, he was lifted up, and a cloud took him out of their sight…

Then they returned to Jerusalem from the mount called Olivet… and when they had entered, they went up to the upper room, where they were staying… All these with one accord devoted themselves to prayer, together with the women and Mary the mother of Jesus, and with his brethren…

When the day of Pentecost had come, they were all together in one place. And suddenly a sound came from heaven like the rush of a mighty wind, and it filled all the house where they were sitting. And there appeared to them tongues as of fire, distributed and resting on each one of them. And they were all filled with the Holy Spirit and began to speak in other tongues, as the Spirit gave them utterance.

 – Acts 1:8-9,12-14;2:1-4

If you’re looking for a novena to pray between now and Pentecost, my new favourite is the novena to one of my favourites, Pier Giorgio Frassati. What’s you’re favourite Novena?
