many C. of E. bishops have just published strong criticisms of New Labour over the state of our society, deterioration of our values, etc.

Indeed so. A bishop of my acquaintance was famously dismissed New Labour as a '...bunch of mushy mouthed mother-fuckers...', not that they're any better of course. 1 in 5? Personally I'd sack the lot of the sorry bastards, dissolve the Church of England and return all theological, cultural, pastoral and historical Christian authority to the Vatican where it rightfully belongs. I hereby call for Vatican 3 - The Reckoning.
