One of the principles most firmly maintained by Luther was that there should be no resort to secular power in support of the Reformation, and no appeal to arms for its defense. He rejoiced that the gospel was confessed by princes of the empire; but when they proposed to unite in a defensive league, he declared that “the doctrine of the gospel should be defended by God alone.... The less man meddled in the work, the more striking would be God’s intervention in its behalf. All the politic precautions suggested were, in his view, attributable to unworthy fear and sinful mistrust.”—The Great Controversy, 209. SPCCSR 91.2
