“For when any institution of human character or composition trespasses or exceeds the limits of God-given authority, then we are not under obligation to obey. (The violation of a law humanly imposed, and not the legitimate exercise of God-given authority, does not involve sin.) Nothing is sin except that which involves the violation of a divine obligation. There is only one Lawgiver. If the ordinances of men require us to violate the law of God, then we must obey God rather than men and must violate the human ordinance. If human ordinances do not require us to sin but are in excess of divinely authorized prerogative, then compliance is to be determined by expediency in relation to all the circumstances of the situation.”
