A typical statement concerning the inerrancy of the Bible reads “The Scriptures are without error in the original autographs.” The problem with this statement arises in Scripture itself. We read about what happened to one original autograph in Jeremiah 36:23 (ESV) “As Jehudi read three or four columns, the king would cut them off with a knife and throw them into the fire in the fire pot, until the entire scroll was consumed in the fire that was in the fire pot.” (The complete story of this event is contained in Jeremiah 36:15-30). Fortunately for us and others, that manuscript was rewritten and we have many other prophecies and stories from the life of Jeremiah.
We do not know what happened to the other original autographs but we do know that none of them are now available to scholars. We do know that Jesus and the apostles had confidence in the reliability of the copies of Scriptures they knew, whether in Hebrew or in the Greek translation known as the Septuagint.
What would we do if we had an inerrant Bible? I think we might concentrate too much on the content of the Bible and too little on developing the proper relationships we should have with each Person of the Trinity. My own tendency would be to (figuratively) beat up my fellow Christians with the certainty of my own interpretations. An inerrant Bible would be no easier to understand in all its passages than the one we have.
We need to be helped in our spiritual growth and I am not sure an inerrant Bible would not just make our love of physical religion, all the things we do, even stronger and make meditation and contemplation even less a part of our lives. I believe God knew what he was doing when he made even the tablets of the Ten Commandments unavailable for our worship.
I believe that it is not the content and form of the original manuscripts that should be of major concern to us but that we have the living word of God in the documents we do have. Thus, we can celebrate the revelation that has been preserved for us.
