Franklin Mason argues that Perfect Guide Inerrancy, as opposed to perfect truth inerrancy, is what is needed. Please do follow the link back to his original discussion of Perfect Guide Inerrancy,
This is an attempt to avoid the conclusion of what I call the inerrancy or chaos argument. The idea of the inerrancy or chaos argument is that without some firm doctrine of biblical inerrancy, theology will sooner or later give away the store. Everything that our sinful hearts don't want to believe, or whatever doesn't fit with the Zeitgeist, will be swept aside, and Christianity reduced to platitudes.
On the other hand, we want to avoid the kind of literalism that led Martin Luther to condemn heliocentrism because it conflicted with a literal reading of the sun standing still for Joshua, which of course also led the Church to make Galileo be silent about heliocentrism.
C. S. Lewis wrote two letters two American writers relevant to the inerrancy issue, which might be helpful in developing Mason's project. As would his chapter on Scripture in Reflections on the Psalsm.
