The New Testament
How Do We Know for Sure?
Richard B. Gaffin, Jr.
Why does the church accept the 27 books of the New Testament as canon? How do we know there is not some document that may some day be discovered and deserve to be included? Alternatively, how do we know that something has not slipped in that does not really belong?

It was a slow process covering roughly 300 years before the Canon accepted in the church was the same as our 27-book canon. Athanasius’s so-called Easter Letter of 367 is apparently the first official, ecclesiastical decision to that effect. And there were significant differences at earlier stages even among orthodox figures. Why, for instance, did the Shepherd of Hermas, despite initial support, eventually go by the board, while 2 Peter, at first subject to much uncertainty, ultimately found a secure place in the Canon?. . .
