"If only Jesus were an ecosystem"

With all the local media attention given to Bishop Spong's current visit to Sydney, today's Sydney Morning Herald includes a nicely titled article by Sydney historian John Dickson comparing the media treatment of extreme views in climate change and Jesus studies. His basic argument: if Jesus were an ecosystem, we'd have less patience with voices (such as Spong) so out of touch with contemporary scholarship. But since the field of Jesus-studies is generally perceived to have no consequences, the media are happy to publish anything sensational.
