Is the Reformation over? Is it, as some have suggested, a failed project? In order to answer that question, we must return to the Reformation and its core doctrinal convictions. We must remember that the Reformation, at its heart, was not a political or a social movement but a theological one. The Reformation was birthed out of Martin Luther’s commitment to sola Scriptura—the “material principle” of the Reformation. Sola Scriptura affirmed that the Bible alone is the final, infallible authority for life and doctrine. This commitment to Scripture shaped the contours of Reformation conviction. It was this commitment to the ultimate authority of Scripture that gave the Reformers the courage to separate from Rome in their proclamation of the gospel.
