AskThePriest.org: The Heresy of Literalism:

"It all started with Martin Luther, and his doctrine of Sola Scriptura, although Luther was certainly not a literalist. From that point, a higher emphasis is laid on Scripture. Moody and Darby in the 1800s contribute to this heightening, but it is not until the early 1900s that a true doctrine of scriptural infallibility emerges.

The term fundamentalist is a self-applied term that is derived from the collection of essays, The Fundamentals: A Testimony To The Truth written between 1910 and 1915. The first of the fundamentals is the literal inerrancy of scripture. The formulation of a doctrine of textual inerrancy can be found here - it is a 20th-Century American innovation."

This is fascinating. All the arguments against homosexuality are based on the assumption that Scripture is inerrant and that we've always viewed it that way since it was first handed down to us by God. At least, that's what I thought. This seems to suggest otherwise.
