From a post at Reformation 21 entitled The Bonzo Dog Doo Dah Band on Urban Theology
One thing Paul and I did discuss was the current nonsense about cities being special which so dominates the popular evangelical imagination. Not that cities are not important: as areas where there are the highest concentrations of human beings, they are inevitably significant as mission fields. Rather, we were thinking of the `from a Garden to a City’ hermeneutic which jumps from scripture to giving modern urban sprawl some kind of special eschatological significance. Was there ever a thinner hermeneutical foundation upon which so much has been built? OK, there probably has been, but this is still a whopper.
And more:
This superiority of the urban at an economic level has been reinforced with a veritable arsenal of cultural weapons, from the linguistic (e.g., city life is often described as `authentic’ while that in the suburbs is `artificial’) to the ethnic (city folk are seen as quick, sharp, savvy, sophisticated; country folk as slow, thick, simple – think accents, whether Mississippi or Gloucestershire). One could easily make the case for the existence of an urbanism which parallels Edward Said’s orientalism. Now the church is apparently on the bandwagon: missions to the city have a cool, hip status; missions to the bumpkins and the yokels (that’s English for `redneck’) not being quite so sexy. The secular aesthetic receives biblical sanction through baptism by a dodgy hermeneutic.

Uncle Carl. Still grumpy.
Yeah, but he says it in style.
The whole ‘city’ hermeneutic still seems like middle-class aspiration seeking a rationalization.
