The New Testament (NT) is the second division of the Christian biblical canon. It discusses the teachings and person of Jesus, as well as events relating to first-century Christianity. The New Testament's background, the first division of the Christian Bible, has the name of Old Testament, which is based primarily upon the Hebrew Bible; together they are regarded as Sacred Scripture by Christians.
The New Testament is a collection of 27 Christian texts written in Koine Greek by various authors, forming the second major division of the Christian Bible. It includes four gospels, the Acts of the Apostles, epistles attributed to Paul and other authors, and the Book of Revelation. The New Testament canon developed gradually over the first few centuries of Christianity through a complex process of debate, rejection of heretical texts, and recognition of writings deemed apostolic, culminating in the formalization of the 27-book canon by the late 4th century. It has been widely accepted across Christian traditions since Late Antiquity.
