“The Limit of this obligation to obedience [to the civil government] will be found only when we are commanded to do something contrary to the to the superior authority of God (Acts iv. 19; v. 29); or when the civil government has become so radically and incurably corrupt that it has ceased to accomplish the ends for which it was established. When that point has unquestionably been reached, when all means of redress have been exhausted without avail, when there appears no prospect of securing reform in the government itself, and some good prospect of securing it by revolution, then it is the privilege and duty of a Christian people to change their government - peacefully if they may, forcibly if they must.”
