From Apprising Ministries:
The fact is that Tony Jones openly advocates somewhat obscure “spiritual disciplines” of contemplative mysticism. Some of these originated with apostate eastern “Desert Fathers and Mothers” such as Contemplative Prayer–so-called “Christian” meditation–Lectio Divina, praying to Icons and the Labyrinth, most of which would germinate within the anti-biblical monastic system of the apostate Church of Rome. Jones is not alone in advocating this type of spirituality because these types of mystical practices and others form a core doctrine found in most Emergent Churches.
As such he is in fact one of many spreading New Age type teachings of spirituality which are somewhat comparable to the Gnosticism that spread through much of the early Christian church in the first several centuries. And the seeking of mystical gnosis is a basic staple of the Emergent Church movement as was reported on the PBS Special in July of 2005: “Individual emerging churches may look different, but they share many characteristics; most are casual with a big emphasis on the experiential.”
