Let us prepare for the coming of our Lord and King by meditating on the great mystery of God's love and the story of the first Chirstmas.From: catholicism.about.com
While a novena is normally a nine-day prayer, the term is sometimes used for any prayer that is repeated over a series of days. This prayer is often called the "Christmas Novena" or the "Christmas Anticipation Prayer," because it is prayed 15 times every day from the Feast of Saint Andrew the Apostle (November 30) until Christmas. The first Sunday of Advent is the Sunday closest to the Feast of Saint Andrew.
The novena is not actually addressed to Saint Andrew but to God Himself, asking Him to grant our request in the honor of the birth of His Son at Christmas. You can say the prayer all 15 times, all at once; or divide up the recitation as necessary (perhaps five times at each meal).
Saint Andrew Christmas Novena
Hail and blessed be the hour and moment in which the Son of God was born of the most pure Virgin Mary, at midnight, in Bethlehem, in piercing cold. In that hour, vouchsafe, O my God! to hear my prayer and grant my desires, through the merits of Our Savior Jesus Christ, and of His Blessed Mother. Amen.
