I recently found a cool site Askanydifference, with interesting articles, I read them day and night. Found there an article about religions. The difference between the Catholic Bible and King James Bible is that the Catholic Bible imbibes the original version of the Holy book containing 46 books of the Old Testament and 27 Books of the New Testament. Whereas, the King James Bible contains translations of old and new testaments, however, it is devoid of the 7 Apocrypha’s making it 39 Old Testament books.
