The UK is a Christian country? Really? Something like 5% of the population attend church regularly apparently. I wouldn't call that a Christian country.
I am an atheist in religious terms: I have no faith in any god. But my cultural references are shaped (alongside of her factors) by Christianity: art, music, lots of literature. My values are influenced by Christianity.
Of course many of these values are at the heart of other religions too, but the philosophy in the parables is core to my approach to the world.
It’s all part of my identity as a British person: Wry humour, putting up with the weather, queueing, welling up at Christmas Carols sung in the square by a choir, bonfire night, harvest festival, espousing chicken tikka masala as the nations favourite dish, Easter eggs, being tolerant of eccentricity, and so on.
