Christian nation theory is wrong
SO now, according to Lord (Rowan) Williams, this is a post-Christian country. But there is still that attempt to lead us back to Christianity, as we are told that we are still affected by the legacy of Christian influence.
Any study of our history makes it hard to claim that this was ever a truly Christian country.
It may, for some time, have been a church-attending country, in the days when one man owned one, or more, villages and the peasants had to go to church or risk losing their cottages and livelihood.
As science and technology progress, the country can only move further away from religion.
