Since Dr. Roger Olson recently posted his views on the doctrine of inerrancy, myself and a few other bloggers have been discussing it at Arminian Today.
One thing that really hasn't come up in that discussion is can you even consider something infallible if it contains errors? Now, when speaking of inerrancy, one isn't speaking of things like rounding numbers or possible spelling errors, one is speaking of what the text is teaching, asserting, and affirming. I could accept that the original documents of scripture could contain spelling errors and still be inerrant. What cannot be in error is what the scripture affirms as the truth. But when many give up the doctrine of the inerrancy of the Bible, they want to continue affirming that it is infallible; that it won't lead you astray.
Assuming that inerrancy is how I've defined it here, and not some strict wooden literalism, if you do give up that doctrine, how do you maintain the doctrine of infallibility? If the Bible contains errors in what it asserts to be the truth, does that not de facto lead one astray? Even if it's on something minor, like what King Saul said to David at some point, does that not lead you astray on what happened at that point? How could you maintain infallibility without inerrancy?
