This article called The Labyrinth -- A Walk to Life or a Walk to Death? tells why the Labyrinth was adopted by the Roman Church and how the Labyrinth predates Christianity by over a millenium.  It also tells how it is a part of the New Age occult. http://www.crossroad.to/articles2/04/labyrinth-muse.htm Here is another excellent article on it as well which tells a more about it being in the Catholic cathedrals during the Middle Ages http://www.letusreason.org/Nam30.htm  This article also states “The labyrinth has its origins in ancient pagan rituals, most famously at Knossos in ancient Crete, where one was located in the basement of a palace where the mythic man-eating Minotaur was said to roam. According to ancient lore, the hero Theseus journeyed through the labyrinth to slay the evil Minotaur. Theseus' doubled-headed ax was called a 'labrys,' from which the word labyrinth was derived. Ceremonies re-enacting this myth as a ritual labyrinth walk are still performed today. Other labyrinths have been tied to fertility rites and goddess worship." (M. Tooley, September 2000).
