what is new testament and old testament in the bible
Old Testament The Old Testament (abbreviated OT) is the first part of Christian Bibles based primarily upon the Hebrew Bible (or Tanakh), a collection of ancient religious writings by the Israelites[1] believed by many Christians and religious Jews to be the sacred Word of God.[2] Its counterpart is the New Testament, the second part of the Christian Bible. The books that comprise the Old Testament canon differ between Christian Churches as well as their order and names. The most common Protestant canon comprises 39 books, the Catholic canon comprises 46 books, and the canons of the Eastern Orthodox and Oriental Orthodox Churches comprise up to 51 books.[3] The 39 books in common to all the Christian canons corresponds to 24 books of the Tanakh, with some differences of order, and there are some differences in text. The additional number reflects the split of texts in the Christian Bibles into separate books, for example, Kings, Samuel and Chronicles, Ezra–Nehemiah and the minor prophets into separate books. The books which are part of a Christian Old Testament but which are not part of the Hebrew canon are sometimes described as deuterocanonical. In general, Protestant bibles do not include deuterocanonical books in their canon, but some versions of Anglican and Lutheran bibles place such books in a separate section called Apocrypha.
New Testament Collections of related texts such as letters of the Apostle Paul (a major collection of which must have been made already by the early 2nd century)[7] and the Canonical Gospels of Matthew, Mark, Luke, and John (asserted by Irenaeus of Lyon in the late-2nd century as the Four Gospels) gradually were joined to other collections and single works in different combinations to form various Christian canons of Scripture. Over time, some disputed books, such as the Book of Revelation and the Minor Catholic (General) Epistles were introduced into canons in which they were originally absent. Other works earlier held to be Scripture, such as 1 Clement, the Shepherd of Hermas, and the Diatessaron, were excluded from the New Testament. The Old Testament canon is not completely uniform among all major Christian groups including Roman Catholics, Protestants, the Greek Orthodox Church, the Slavic Orthodox Churches, and the Armenian Orthodox Church. However, the twenty-seven-book canon of the New Testament, at least since Late Antiquity, has been almost universally recognized within Christianity (see Development of the New Testament canon).
