The death of Christianity?

Recent article in The Spectator on the decline of the church in the UK; and a blog on a similar theme.

A basic reason that Christians aren't taught their faith, don't engage with its history and literature, know nothing of theology or apologetics and cannot think of the faith implications of anything. Thus they are led about by the wet and the left and anyone with a specious argument about anything, or they simple 'just believe' an alternative inarticulately.
