Cultural Christians are people who don't believe in God but still want to call themselves Christians. Everyone's at it one way and another aren't they? Big butch men calling themselves women, white women calling themselves black - there are no limits really and with that in mind I now declare myself Miss Fucking World for every year since it's inception, Mrs Mensa Genius of the universe, Bill Gates's wallet, The Duchess of Fucking Everything and an all round Damned Good Egg (if that's alright with the easily offended amongst us?).
But it's not religious, it's cultural. That's rather the point.
So traditions, sayings, music, names, food etc (as well as high days and holidays, feasts and festivals) come from the religious tradition of your forefathers.
I find it bizarre that people are sneered at for maintaining some cultural traditions after shedding religious belief.
I find it even stranger that Cultural Christianity seems to get it in the neck most.
Am I making more sense now?
