Bible

Named for the Greek word "Biblios" ("Book") and considered the Holy Book by both Judaism and Christianity (which--at least at its inception--was considered a sect, branch, or spinoff of Judaism named "Messianic Judaism"--regardless of whether it was considered apostate, not-necessarily heretical but still heterodox, or legitimate/orthodox). The parts of the Bible that Normative (Mainstream, Non Messianic) Judaism and Messianic Judaism agree on are the books of Torah, Nevi'im, and Ketuvim--often called Tanakh. Where Judaism and Messianic Judaism divide is the point at which the New Testament (called "Hadashah" for "New" or "News") is eligible to be considered as part of Tanakh (written by some Messianic Jews as "TaNaKH" to include "Hadashah"; written as "TaNaKh" by some Non-Messianic Jews).
