“Luther and Calvin were explicit that the intent of Scripture was not to teach natural science, and their employment of accommodation served to relieve Scripture of that task. But beginning in the seventeenth century, scholars expected Scripture to serve as a framework for comprehensive knowledge of the world, including the interests of natural science. Demonstrating scientific concord became a necessary task to prove the validity of the Bible. By the time of Old Princeton, an old earth was commonly accepted among educated conservatives, who continued the tradition of scientific concordism.”
