A map is not enough

Been a while since I discussed Scripturalism. According to standard Scripturalist epistemology, the Bible is the only source of knowledge. All other sources of information are consigned to opinion.

Scripturalism is like giving someone a map. The Bible is the roadmap. That's all you need–or is it? 

Problem is, a map in itself, however accurate and detailed, is useless unless you know where you are in relation to the map. To be able locate your destination, and the route to take, you must be able to locate yourself on the map. But that information is not on the map. The map doesn't show you. So you must be able to compare the map to recognizable street signs or landmarkks to get your bearings. To use the map, you need information outside the map. 

Ryan Hedrich may be able to make the necessary modifications to Scripturalism. We'll see how that goes.
