Bible, also called the Holy Bible, the sacred book or Scriptures of Judaism and of Christianity. The Bible of Judaism and the Bible of Christianity are different, however, in some important ways. The Jewish Bible is the Hebrew Scriptures, 39 books originally written in Hebrew, except for a few sections in Aramaic. The Christian Bible is in two parts, the Old Testament and the 27 books of the New Testament. The Old Testament is structured in two slightly different forms by the two principal divisions of Christendom. The version of the Old Testament used by Roman Catholics is the Bible of Judaism plus 7 other books and additions to books (see the accompanying table); some of the additional books were originally written in Greek, as was the New Testament. The version of the Old Testament used by Protestants is limited to the 39 books of the Jewish Bible. The other books and additions to books are called the Apocrypha by Protestants; they are generally referred to as deuterocanonical books by Roman Catholics.

The term Bible is derived through Latin from the Greek biblia, or "books," the diminutive form of byblos, the word for "papyrus" or "paper," which was exported from the ancient Phoenician port city of Biblos. By the time of the Middle Ages the books of the Bible were considered a unified entity.�?/SPAN>

Christianity has three central Divisions Catholcism, Orthodox Church, and Protestantism.  The next page has a table comparing a few of the differences between these three divsions.
