Stephen Nichols on what was accomplished in the Reformation:
Luther spawned more than a singular alternative to the Roman Catholic Church. Yet, while there are alternatives, to be sure, at the heart of these various Protestant groups who remain faithful to the gospel there is a common core: a theological center that consists of the authority of Scripture alone and insists that salvation comes by faith alone through God’s grace alone—and that this salvation comes through the work of Christ alone. This is the lasting legacy of the Reformation—not the discovery of truths, but their recovery and their return to the heart and center of the church. (Pages from Church History, 35)
