The Bible is the sacred scriptures of Judaism and Christianity. The Christian Bible consists of the Old Testament and the New Testament, with the Roman Catholic and Eastern Orthodox versions of the Old Testament being slightly larger because of their acceptance of certain books and parts of books considered apocryphal by Protestants. The Hebrew Bible includes only books known to Christians as the Old Testament. The arrangements of the Jewish and Christian canons differ considerably. The Protestant and Roman Catholic arrangements more nearly match one another.
