The Bible is a book of enormous cultural and historical significance for Britain. The KJV was very influential in the development of British religous traditions and even the English language.
It does not seem excessive to devote a day to its fourth centennial. All (educated) Britons ought to have some basic understanding of the central elements of the book.
The National Secular Society does excellent work in protecting the British from privileges granted to organised mass religion, and in lifting the UK above superstitions, witch hunts, and Middle Eastern death cults. But it should pick its battles better. (If it is at all interested in starting any serious fight over this, which I'm not so sure about)
