The civil magistrate cannot function without some ethical guidance, without some standard of good and evil. If that standard is not to be the revealed law of God… then what will it be? In some form or expression it will have to be the law of man (or men) - the standard of self-law or autonomy. And when autonomous laws come to govern a commonwealth, the sword is certainly wielded in vain, for it represents simply the brute force of some men’s will against the will of other men.
The negative penalties of the Old Testament case laws were not harsh but just, not a threat to society but rather the necessary judicial foundation of civic freedom… the Old Testament was harsh on criminals because it was soft on victims.
Those who hold to the Christian faith see law as an ultimate order of the universe. It is the invariable factor in a variable world, the unchanging order in a changing universe. Law for the Christian is thus absolute, final, and an aspect of God's creation and a manifestation of His nature. In terms of this, the Christian can hold that right is right, and wrong is wrong, that good and evil are unchanging moral categories rather than relative terms.From an evolutionary perspective, however, we have a very different concept of law. The universe is evolving, and the one constant factor is change. It is impossible therefore to speak of any absolute law. The universe has evolved by means of chance variations, and no law has any ultimacy or absolute truth. As a result when we talk about law, we are talking about social customs or mores and about statistical averages. Social customs change, and what was law to the ancient Gauls is not law to the modern Frenchmen. We can expect men's ideas of law to change as their societies change and evolve. Moreover, statistics give us an average and a mean which determine normality, and our ideas of law are governed by what is customary and socially accepted.
Of all the wicked heresies and threatening movements facing the church in our day, when Westminster Seminary finally organized their faculty to write something in unison, they gave their determined political efforts not to fight socialism, not to fight homosexuality, not abortion, not crime and mayhem in our society, not subjectivism in theology, not dispensationalism, not cultural relativism, not licentiousness, not defection from the New Testament, not defection from the Westminster Confession of Faith, all of which are out there and they can give their legitimate efforts to… boy the thing they had to write about was theonomy! How many times can a man turn his head and pretend that he doesn’t see the problem?
Our modern world defined God as a ‘religious complex’ and laughed at the Ten Commandments as OLD FASHIONED. Then, through the laughter came the shattering thunder of the World War. And now a blood-drenched, bitter world — no longer laughing — cries for a way out. There is but one way out. It existed before it was engraven upon Tablets of Stone. It will exist when stone has crumbled. The Ten Commandments are not rules to obey as a personal favor to God. They are the fundamental principles without which mankind cannot live together. They are not laws — they are The Law.
