Infallibility does not equal literal translation and literal intent. For instance, back to the subject, the earth is not 6000 yeard old. It just isnt. It can be said beyond a reasonable doubt. You are the one facing a xrisis of authority because your interpretation blows up your entire faith because the earth is 6 billion years old. It is sad for you because the fact that the earth is 6 billion years old is really inconsequential unless you are an evangelical. Perhaps you should consider Catholicism or Episcopalianism and these mundane nuances wouldnt cause you such crises.
What is not negotiable is for Christians to confess God as Creator. My question for you, then, is whether you can wholeheartedly affirm the Apostles Creed (confessed by Catholics and Episcopalians during worship), which states: "I believe in God the Father, maker of heaven and earth..."
