There are certain photos which become unforgettable icons of particular movements or moments in history. The naked Vietnamese girl, enflamed by napalm, epitomised the demise of American power in Vietnam in the 1960s, for example.

 Perhaps the recent photograph of the Anglican altar dedicated, not to Jesus, but to the NHS, will come to symbolise the tipping point of the capitulation of the Church of England into religious statism, and secular moralism?

The relationship between politics and religion is, of course, a fraught and complex one.
