Personally I will never accept the faith of Christianity, nor it being made part of our heritage and culture in the present at all, even ignoring its use of propping up a birth-based hierarchy. It''s dead. It was never rational,
OMG, this shows a devasting lack in understanding the connectedness of faith to culture. Magna Carta provided the foundation of English common law, all based on Judeo-Christian ethics. Not based on the Napoleonic system they have in France (which means you are guilty until you are found Not Guilty), not based on Mormonism, Buddhism, Shintoism, Islam etc.
If you do not know some history, then you will never understand who/what you are and how you came to be living how you live. You will never have a full sense of self.
