Swing and a miss, Ratzo.
It took a millennium and a half for the reformation to try to straighten out Scripture.
The point I made was that Luther incorrectly removed this.
So which would you use to inform your life and society? If you said, "The Bible", then even God thinks you're a moron. Because, way before there was scripture, there was man's ability to reason.
Read the Gospel; specifically read how Jesus reacted to Thomas' skepticism, and his message about those who haven't seen and still believe.
Man's ability to reason is deeply flawed. Man's "reason" once told the Egyptians it was OK to use the Hebrews as slaves. Man's "reason" today says it's OK for women to butcher their children in the womb.
