Criteria for the sacred Christian books

The first collection of these Christian books (biblia) was the Pauline letters and the Acts of the Apostles around the year 100 CE.  The collection of the four canonical gospels of Matthew, Mark, Luke, and John was present by the year 200 CE.  By 367 CE, Christians had arrived at a consensus about the twenty-seven books of the New Testament that we have today.  The criteria for the sacred books of the biblical New Testament were a connection with the apostles and one of the major Christian communities, while being orthodox in its views.
