Here's what I said in a seminar I gave about Luther a few months ago:
Do we trust the bible because we believe in Jesus, or do we believe in Jesus because we trust the Bible?
Some people might say it’s just two sides of a coin and you can’t have one without the other. Luther would probably have said quite simply: JESUS. Jesus always comes first. You could take away the bible forever and Jesus would still be LORD. But more likely that wouldn’t be Luther’s emphasis - what he would want to stress was: the Bible’s only lasting value is that it points to and glorifies the God who has saved us through Jesus Christ.
Further to that I remember a story* about T.F. Torrance teasing a theology student at Edinburgh. After the student had just given a very impassioned presentation on the crucial importance of the authority of scripture, and how it serves as the foundational building blocks of our faith and understanding, He then invited questions from the floor. To which Torrance simply put up his hand and asked... "Yes, but will there be bibles in heaven?"
The student was speechless.
It's Christ that has the ultimate authority, not scripture.
Scripture serves Him.
*'Story' meaning I know I heard it but can't find any reference to it anywhere. Any ideas? Answers on a postcard please...
