Among the 75 arrangements at the festival will be 12 depicting the Twelve Days of Christmas. The Twelve Days of Christmas was written in England as one of the "catechism songs" to help young Catholics learn the basics of their faith. In short, it was a memory aid. Since the song sounded like rhyming nonsense, young catholics could sing the song without fear of imprisonment. The authorities would not know that it was a religious song. Actually, the catechism to which it referred was rather ecumenical so could probably be claimed to be protestant if cornered.

The song's gifts had hidden meanings to the teachings of the Catholic faith. The "true love" mentioned in the song doesn't refer to an earthly suitor, but it refers to God Himself. The "me" who receives the presents refers to every baptized person. i.e. the church.

Here is a complete list of the 12 symbols with their meanings:

1 Partridge in a pear tree = The One true God revealed in the person of Jesus Christ
2 Turtle Doves = The Old and New Testaments
3 French Hens = Faith, Hope and Charity

5 Golden Rings = The first Five Books of the Old Testament, the "Pentateuch" which contain the law condemning us of our sins.
6 Geese A-laying = the six days of creation
7 Swans A-swimming = the seven gifts of the Holy Spirit, the seven sacraments of the Catholic faith
8 Maids A-milking = the eight beatitudes
9 Ladies Dancing = the nine Fruits of the Spirit
10 Lords A-leaping = the ten commandments
11 Pipers Piping = the eleven faithful apostles
12 Drummers Drumming = the twelve points of doctrine in the Apostle's Creed
