The New Testament (Koine Greek: Ἡ Καινὴ Διαθήκη, Hē Kainḕ Diathḗkē) is the second major division of the Christian biblical canon, the first division being the Old Testament. Unlike the Old Testament or Hebrew Bible, of which Christians hold different views, the contents of the New Testament deal explicitly with 1st century 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 (along with readings from the Old Testament) into the various Christian liturgies. The New Testament has influenced not only religious, philosophical, and political movements in Christendom, but also left an indelible mark on its literature, art, and music.
