This is paganism being welcomed into the church. The labyrinthe is an occult path of the dead. Successful navigation of it led one to heaven; the lost wandered it forever in terror, ending up in the center pit from which there was no escape. Arcane knowledge (gnosis) of traversing it or a suitable guide, therefore, was necessary part of pagan religion.
In other incarnations, it serves a gnostic purpose of meditation (something like a rosary someone mentioned above), not the "inner-peace" type, but the "path," again, to enlightenment.
Prayer paths, crystals, stones, trinkets, relics, junk. All part of the big lie, to draw people away from Christ, and honest, true communion with God. Will-worship, self-made religion--if people need something extra beside that which is God-given, it is because they either do not have true faith within to appreciate what is God-given; or they are feeding on husks, and are not feeding on the bread of life.
