Time was when the opinion of the Archbishop of Canterbury carried a good deal of weight - so much so that it required four knights to go knock him off when he was deemed too 'turbulent.'
That may still be the case (the weight, that is, not the knights knocking him off - we hope), but we'll have to see how far the latest declaration from Dr Rowan Williams, the current Archbishop of Canterbury resonates: While the Telegraph's paraphrase, "Go Green to Save Your Soul," may be overstated, he made it clear that people should live in a way that "honours rather than endangers the life of the planet."
In a lecture at Southwark Cathedral, Dr Rowan Williams said the Christian response to climate change is to immediately minimise any impact on the environment.
He cited examples of switching off appliances, taking holidays at home and growing your own food in an allotment. He said it would not only reduce an individual's carbon footprint but through "re-connecting" with nature help people to get back in touch with the human soul.
The Archbishop even recommends walking in the rain in order to reconnect with nature, scaling back on air travel and concentrating on what makes the soul human in the "biblical sense."
All that spiritual stuff is fine and good, but given his earlier condemnation of capitalists for "idolatry" and call for them to "repent" for causing the economic collapse, the anti-consumerist underpinnings of some of his latest suggestions could be seen by some in power as, dare we say, "turbulent."
Hope he's got good bodyguards.
