Israel came to recognize the Bible’s special authority even through nowhere in the OT is a book said to be inspired by God. What the OT contains is Israel’s belief that God revealed Himself in history and that history was guided by God’s Spirit. The writers of the OT teach that the breath of God came upon Moses, the Judges, Saul, David, the Prophets, etc. These specially chosen persons, with the help of God’s Spirit interpreted Israel’s history.
The authors of the OT and NT books did not think of themselves writing inspired writings. In the first years after the resurrection, there was little thought given to writing down a Christian library. Some of this was undoubtedly due to the example of the Lord Himself who, like the rabbis of the time, taught by the spoken word, which in turn was remembered and discussed by disciples. There was no need for writing while the Apostles were still alive to clarify or verify anything uncertain.
Many of the traditions found in the bible circulated for years, even centuries, in oral form before they were written down. Many authors were responsible for the material which was created for, and received by, a believing community. it was in this dynamic social setting that the sacred traditions were developed, interpreted, and synthesized before they became a book of Scripture. The meaning of a biblical text was arrived at in different ways throughout the history of interpretation. Jewish scholars had long recognized that the revealed Word of God had many possible meanings.
There came a time when the Church recognized certain writings as not just inspired by the authors that wrote them, or were used in the various Churches, yet, the writers themselves for example the Apostles who wrote or St. Paul who wrote his letters to the various Churches ever thought of themselves as inspired or that what they wrote was inspired and canonical. That was left up to the Church to decide which books were indeed inspired and therefore supplemented the oral teaching of the Apostles who were taught by Christ Himself. This led at some point to some type of a canon so that those books or writings not teaching what the Apostles taught or of that of Christ Himself, for example gnostic writings would not be considered sacred Scripture.
