Yes, of course, in the empirical sense and I've been debating them for years and I've read and or heard the claim repeatedly. They believe it is perfect and infallible in every way: spiritually, as a work of literature and historically. I find it odd that it's the first you've ever heard of this, for it's quite common.
Biblical literalism - Wikipedia
The vast majority of evangelical and fundamentalist Christians regard the Biblical text as clear, and believe that the average person may understand the basic meaning and teachings of the Bible. Such Christians often refer to the teachings of the Bible rather than to the process of interpretation itself. The doctrine of clarity of the text does not mean that no interpretative principles are necessary, or that there is no gap between the culture in which the Bible was written and the culture of a modern reader. On the contrary, exegetical and interpretative principles come into play as part of the process of closing that cultural gap.
