Richard Dawkins writes in the Guardian:
A native speaker of English who has never read a word of the King James Bible is verging on the barbarian. In the week after the 2011 census, my UK Foundation commissioned Ipsos MORI to poll those who had ticked the Christian box. Among other things, we asked them to identify the first book of the New Testament from a choice of Matthew, Genesis, Acts of the Apostles, Psalms, “Don’t know” and “Prefer not to say”. Only 35% chose Matthew and 39% chose “Don’t know” (and 1%, mysteriously, chose “Prefer not to say”). These figures, to repeat, don’t refer to British people at large but only to those who self-identified, in the census, as Christians.
European history, too, is incomprehensible without an understanding of the warring factions of Christianity and the book over whose subtleties of interpretation they were so ready to slaughter and torture each other.
