The New Testament is the name given to the second and final portion of the Christian Bible. Jesus is its central figure.
The term “New Testament” came into use in the second century during a controversy among Christians over whether or not the Hebrew Bible should be included with the Christian writings as sacred scripture. The New Testament presupposes the inspiration of the Old Testament. Some other works which were widely read by early churches were excluded from the New Testament and relegated to the collections known as the Apostolic Fathers (generally considered orthodox) and the New Testament Apocrypha (including both orthodox and heretical works).
The New Testament is a collection of 27 books of 4 different genres of Christian literature (Gospels, one account of the Acts of the Apostles, Epistles and an Apocalypse).
