Important to our prior discussions?

Nunblog had an interesting thought about Biblical inerrancy, something that I think is at least slightly important to conversations we've had in our comments before (Matt, Greg, etc.) As part of arguments for sola scriptura (see the article in a previous post from Apologetics Press), sometimes Protestants argue that they can know what books are "inspired" because of historical or scientific accuracy. If this is true, we might have to throw out the book of Matthew, because the mustard seed, indeed, is not the smallest of all seeds. Whether or not someone can make an excuse for this discrepancy is irrelevant. Anyone can twist anything to make it sound good with enough thought. More importantly is that we shouldn't be reading the Bible like a science text book. Remember that we should be looking for the theological arguments and the issues of faith and morals, on which it will be infallible (much like the Church and Sacred Tradition).
