The New Testament and Old Testament are two parts of the Bible. The Bible forms the basis of the faiths of Judaism and Christianity, whose adherents believe that it contains the word of God.The New Testament comprises the four Gospels (Matthew, Mark, Luke and John), which record the teachings of Jesus Christ and recount his life, death and Resurrection; the Acts of the Apostles; the letters written to the early Christian communities; and the Apocalypse, or Book of Revelation.
