Tim Challies has a old post called Experience The Labyrinth: (Insert New Age Music Here) which is getting some new life in the comments section - some think its a Satanic tool, and others who think its a great way of praying with focus - its an interesting discussion.
Many ministries and websites that are anti-emergent have a problem with Labyrinths -Lighthouse Trails, EmegentNo, Steven Muse. But others are using them in an old school way or reinterpreted as a multi-media journey of of worship. (Labyrinth.co.uk) This is a BIG point of contention and I don't think we will get any resolution here.
Challies asked for some biblical foundation for the idea (not easy for ANY current worship practise) so I left a comment way down the bottom at 74, part of which says this. . .
A labyrinth is simply a "line in the ground" (Mark Pierson's definition). It is a way of creating a journey of motion with points to stop and pray, read, think or act in worship. I have visited Chartes and am not really impressed with the middle age style labyrinth. But a journey of prayer and worship that engages the mind and body - thats different . . that sounds like my own devotional times when i go for a walk and pray over what I see - or when I am involved in a prayer walk around a city.
I find many examples of this kind of worship (some of us call it "navigable") used in the Old Testament. The Feast of Tabernacles had many journeys of motion that the worshippers used to participate in - from one gate to another gate, holding citrons and sticks . . The Psalms of Ascent (Psalm 120-134) were used in (well - there is some disagreement here . .. but either they were read out as worshippers ascended the steps of the Temple, or along the journey/pilgrimage to Jerusalem . . . or maybe both)
Jesus also participated in the yearly pilgrimages to the Festivals, and during his long walks with his disciples, he would often stop in his journey to interact with a fig tree or look at something.
