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. The New Testament is sometimes called the Greek New Testament or Greek Scriptures, or the New Covenant. According to Greek primacy, the original texts were written in Koine Greek by various authors after c. AD 45. Though Jesus speaks Aramaic in it, the New Testament (including the Gospels) was written in Greek because that was the lingua franca of the eastern half of the Roman Empire.
