New Testament (New Testament)

1. The second half of the Christian Bible, includes the four Gospels, the Book of Acts, the Epistles, and the Book of Revelation.

The New Testament (Greek: Καινὴ Διαθήκη, Kainē Diathēkē) is the name given to the second major division of the Christian Bible, the first such division being the much longer Old Testament. Unlike the Old Testament, the contents of the New Testament deal explicitly with Christianity, although both the Old and New Testament are regarded, together, as Sacred Scripture. The New Testament has therefore (in whole or in part) frequently accompanied the spread of Christianity around the world, and both reflects and serves as a source for Christian theology. Phrases as well as extended readings directly from the New Testament are also incorporated into the various Christian liturgies. The New Testament has influenced not only religious, philosophical, and political movements in the Christian world, but also left an indelible mark on its literature, art, and music.

The New Testament is an anthology, a collection of works written at different times by various authors. In almost all Christian traditions today, the New Testament consists of 27 books. The original texts were written beginning around A.D. 50 in Koine Greek, the lingua franca of the eastern part of the Roman Empire where they were composed. All of the works which would eventually be incorporated into the New Testament would seem to have been written no later than the mid-second century.

Collections of related texts such as letters of the Apostle Paul (a major collection of which must have been made already by the early second century) and the Gospels of Matthew, Mark, Luke, and John (defended by Irenaeus of Lyon in the late-second 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 Apocalypse of John and the Minor Catholic Epistles were introduced into canons in which they were originally absent, and other works earlier held to be Scripture such as 1 Clement, the Shepherd of Hermas, and the Diatessaron were excluded from the New Testament (see Antilegomena). Interestingly, although the Old Testament canon is not uniform within Christianity, with e.g. Roman Catholics, Protestants, the Greek Orthodox Church, the Slavic Orthodox Churches, and the Armenian Orthodox Church differing as to which books are included in the Old Testament, the twenty-seven-book canon of the New Testament has, since at least Late Antiquity, been almost universally recognized within Christianity (see twenty-seven book canon; exceptions include the New Testament of the Ethiopian Orthodox Church, the canon of which—like that of the Old Testament—has not been unequivocally fixed and Martin Luther's attempt to exclude four books from the New Testament). The New Testament consists of four narratives of the life, teaching, and death of Jesus, called "gospels"; a narrative of the Apostles' ministries in the early church, called the "Acts of the Apostles" and probably by the same author as the Gospel of Luke, which it continues; twenty-one letters, often called "epistles" in the biblical context, written by various authors and consisting mostly of Christian counsel, instruction, and conflict resolution; and an Apocalypse, the Apocalypse of John.
