Keith Mathison clearly investigates the development of this doctrine from the days of the early church to the fourth-century assault on it, from its recovery during the Reformation to the relativism and individualism that permeates it in today's teaching. In addition, Mathison demonstrates that the widespread misunderstanding of the doctrine of sola Scriptura is eroding the church from within, fueling conversions from Protestantism to other religions, and undermining the relationship among Scripture, church tradition, and individual believers as set forth by the early church and restated by the Reformers.
