Christmas is a key time of year when we see the media contemplate the popularity of religion. This year has been no different, with the Guardian and the Times publishing opinion polls on the subject. The essential result is that a majority of people declare some affiliation to a religion and at least a large minority attend religious services more than once during the year.
This is often difficult for atheist secularists to digest. The Guardian leader article accompanying its survey is a good example(http://www.guardian.co.uk/commentisfree/story/0,,1978092,00.html).
However, to ignore a faith perspective in politics (which is not the same as politics being driven by religion) is to leave out something essential, with the risk that the state becomes separated from the people in some respect. I had a letter published on this, which can be found at http://www.guardian.co.uk/letters/story/0,,1978822,00.html. I believe even people who hold to no particular religious belief would agree.
