The life of a Church may be largely read in its controversies. As the glory or shame of a nation is read upon its battle-fields which tells for what it perilled the lives of its sons, so may the glory or shame of a Church be determined when we know what it fought for and what it fought against; how much it valued; how much it did, and how much it suffered to maintain that truth, and what was the issue of its struggles and sacrifices. Tested in all these ways, the record of the Lutheran Church is incomparably glorious. It has contended for great truths at great sacrifices, and in every conflict in which it has borne a part, truth has ultimately been victorious. A Church which contends for nothing, either has lost the truth, or has ceased to love it. Warfare is painful, but they whose errors create the necessity for it are responsible for all its miseries.
