When discussing the question of inspiration of Scripture, it is important to consider also the way in which the church determined which books were from God and which were not. Most of us take for granted that the New Testament always had twenty-seven books. We may be vaguely aware that Paul mentions a letter he wrote to the church in Laodicea (Col. 4:16) and that there might have been a third letter to the church in Corinth, but beyond that we assume there were no other writings.
In fact, the writing of the books included in the New Testament was spread over a period of more than half a century. However, not all of these books were accepted by the churches as coming from God until about three hundred years after they were written. During that period there were other books, written roughly at the same time as the twenty-seven New Testament books, which were accepted by some churches as inspired.
