When Supreme Court Justice Clarence Thomas appealed to Natural Law theory in some of his legal opinions and writings, there were those on the Senate Judiciary Committee during his confirmation hearings in September 1991 that took exception. The most vocal critic was former Senator and now Vice President Joseph Biden. It was that debate more than 20 years ago that helps us to understand how politics is being done today. Unfortunately, too many in the church are falling into the Natural Law trap.

As long as Thomas defined Natural Law as a transcendental “Higher Law,” the belief that God is its author, as eighteenth-century jurist William Blackstone (1723–1780) did, then his view of Natural Law would not be tolerated.

Biden wrote an article that appeared in the September 8, 2001 issue of the Washington Post ((Joseph R. Biden, Jr., “Law and Natural Law: Questions for Judge Thomas,” The Washington Post (September 8, 1991), C-1.)) in which he defined Natural Law on his terms:

  • It does not “function as being a specific moral code regulating individual behavior.”
  • It is not “a static set of unchanging principles.”
  • It is “an evolving body of ideals.”

Note Biden’s appeal to evolution. Natural law as it was constructed throughout the centuries died in 1859 with the publication of Darwin’s On the Origin of Species. “Charles Darwin destroyed natural law theory in biological science. . . . His successors destroyed natural law theory in social science. In the 1920’s, quantum physics destroyed natural law theory in the subatomic world. This immediately began to undermine modern legal theory.” ((Gary North, Political Polytheism (Tyler, TX: Institute for Christian Economics, 1989), xxii.)) An evolving law means a flexible law that can be manipulated by whoever’s in power.

Today, natural law or otherwise, is whatever the courts say it is. “In our system,” Biden wrote, “the sole obligation of a Supreme Court justice is to the Constitution. Natural justice can supply one of the important means of understanding the Constitution, but natural law can never be used to reach a decision contrary to a fair reading of the Constitution itself.”

This is why the Left wants to be the gatekeepers to the Supreme Court by mandating a liberal litmus test to all prospective judges. Biden’s article does not tell us anything about how we determine what’s right or wrong. Morality is a matter of “individual choice,” and if you can get enough justices to agree with you, then it’s the law, and they are the ones who determine what “individual choice” means. But no matter the form of government, authority and law are foundational.

Every system of government exists to produce or enforce certain laws, and every law necessarily entails a set of moral assumptions. All morality — even that which is usually supposed to be, or touted as being, based upon an “irreligious” or anti-religious” philosophical foundation — is ultimately religious in its nature, since it is founded upon . . . fundamental assumptions about the nature of reality, about God, man, and things, which are taken on (a usually unacknowledged) faith. In this deepest sense, then, the question for every legal system is not whether it will be based upon “religion” but rather which religion or religious philosophy will be its foundation? ((Archie P. Jones, “Christianity and the First Amendment: The Truth about the Religion Clauses of the Constitution,” (unpublished manuscript), 3.))

The modern conception of law is a far cry from the moral principles on which America was founded. Critics point out that America had its forms of injustice, for example, slavery. True enough, but it was because there was a “Higher Law” ethic based on biblical moral values that slavery was overturned. President Harry S. Truman voiced the common and prevailing sentiment of his day:

The fundamental basis of this nation’s laws was given to Moses on the Mount. The fundamental basis of our Bill of Rights comes from the teachings which we get from Exodus and St. Matthew, from Isaiah and St. Paul. I don’t think we comprehend that enough these days.

If we don’t have the proper fundamental moral background, we will finally wind up with a totalitarian government which does not believe in rights for anybody. ((Harry S. Truman, Harry S. Truman: Public Papers of the Presidents of the United States Containing the Public Messages, Speeches, and Statements of the President — January 1 to December 31, 1950 (Washington, D.C.: United States Government Printing Office, 1965), 197.))

We cannot live within the fluid boundaries of legal relativism. There must be a definitive and final legal standard of appeal to justify moral decisions at the personal and governmental levels. If not, then one judge’s opinion is as good (or as bad) as another.

There is a long history in the United States where

John Quincy Adams (1767–1848) stated, “The law given from Sinai was a civil and municipal as well as a moral and religious code; it contained many statutes adapted to that time only, and to the particular circumstances of the nation to whom it was given; they could of course be binding upon them, and only upon them, until abrogated by the same authority which enacted them, as they afterward were by the Christian dispensation: but many others were of universal application — laws essential to the existence of men in society, and most of which have been enacted by every nation, which professed any code of laws.” He added that: “Vain indeed would be the search among the writings of [secular history] . . . to find so broad, so complete and so solid a basis of morality as this Decalogue lays down.” ((John Quincy Adams, Letters of John Quincy Adams, to His Son, on the Bible and Its Teachings (Auburn, NY: Derby Miller & Co., 1848), 61, 70.))

John Witherspoon (1723–1794), the president of what later came to be known as Princeton and a signer of the Declaration of Independence, wrote that “moral law published upon Mount Sinai [is] the publication or summary of that immutable law of righteousness , which is the duty of creatures, and must accompany the administration of every covenant which God makes with man.” ((John Witherspoon, The Works of Rev. John Witherspoon, 4 vols., 2nd rev. ed. (Philadelphia: William W. Woodward, 1802), 4:117–118.))

John Jay (1745–1829), one of the authors of The Federalist Papers and served as the first Chief Justice of the United States Supreme Court, wrote the following in a letter dated April 15, 1818 to his friend John Murray: “[T]he law was given by Moses, not however in his individual or private capacity, but as the agent or instrument, and by the authority of the Almighty. The law demanded exact obedience, and proclaimed: ‘Cursed is every one that continueth not in all things which are written in the book of the law to do them.’” ((John Jay, The Life of John Jay with Selections from His Correspondence and Miscellaneous Papers_, 2 vols._ _(_New York: J & J. Harper, 1833), 2:385.)) In that same letter, he wrote:

The inspired prophets, on the contrary, express the most exalted ideas of the law. They declare that the law of the Lord is perfect, that the statutes of the Lord are right; and that the commandment of the Lord is pure; that God would magnify the law and make it honorable, etc.

Our Savior himself assures us that he came not to destroy the law and the prophets, but to fulfill; that whoever shall do and teach the commandments, shall be called great in the kingdom of heaven; that it is easier for heaven and earth to pass, than one tittle of the law to fail [Matt. 5:17–18]. This certainly amounts to a full approbation of it. Even after the resurrection of our Lord, and after the descent of the Holy Spirit, and after the miraculous conversion of Paul, and after the direct revelation of the Christian dispensation to him, he pronounced this memorable encomium on the law, viz.: “The law is holy, and the commandments holy, just, and good” [Rom. 7:12; also see 1 Tim. 1:8].

There are a number of theologians who are trying to resurrect natural law as a secular alternative to specially revealed law, that is, laws that are found in the Bible. General revelation, natural theology, and natural law can never stand on their own when it comes to moral particulars.

I suspect that advocates of natural law are cheating when they claim that they can build an ethical system independent of special revelation and then further claim that this can be done by moral rebels. Natural law advocates “are like the Irishman who preferred the moon to the sun, because the sun shines in the day-time when there is no need of it, while the moon shines in the night time; so these moralists, shining by the borrowed, reflected light of Christianity, think they have no need of the sun, from whose radiance they get their pale moonlight.” ((A. T. Pierson, The Second Coming of Christ (Philadelphia, PA: Henry Altemus, 1896), 35.))

Dutch theologian Herman Bavinck (1854–1921) had this to say about Natural Theology that is applicable to Natural Law:

There is no such thing as a separate natural theology that could be obtained apart from any revelation solely on the basis of reflective considerations of the universe. The knowledge of God that is gathered up in so-called natural theology is not the product of human reason. Rather, natural theology presupposes, first of all, that God reveals himself in his handiwork. It is not humans who seek God but God who seeks humans, also by means of his works in nature. That being the case, it further presupposes that it is not humans who, by the natural light of reason, understand and know this revelation of God. Although all pagan religions are positive [concrete], what is needed on the human side is a mind that has been sanctified and eyes that have been opened in order to be able to see God, the true and living God, in his creatures. And even this is not enough. Even Christian believers would not be able to understand God’s revelation in nature and reproduce it accurately had not God himself described in his Word how he revealed himself and what he revealed of himself in the universe as a whole. The natural knowledge of God is incorporated and set forth at length in Scripture itself. Accordingly, Christians follow a completely mistaken method when, in treating natural theology, they, as it were, divest themselves of God’s special revelation in Scripture and the illumination of the Holy Spirit, discuss it apart from any Christian presuppositions, and then move on to special revelation. Even when Christians do theology, from the very beginning they stand with both feet on the foundation of special revelation. They are Christ-believers not only in the doctrine of Christ but equally in the doctrine of God. Standing on this foundation, they look around themselves, and armed with the spectacles of Holy Scripture, they see in all the world a revelation of the same God they know and confess in Christ as their Father in heaven. ((Herman Bavinck, Reformed Dogmatics, trans. John Vriend, 4 vols. (Grand Rapids, MI: Baker Academic, 2003–2008), 2:74–75.))

A whole‑Bible ethic is the light by which all social theories gain their reflected light. The further we move away from the light of Scripture, the darker our world becomes. With man’s “cauterized and traumatized” sinful nature, there is no possible way that we can move in the direction of natural law for the development of a comprehensive ethical social theory. “Such has been the deteriorating influence of sin that ‘the [work of the] law written on the heart’ and ‘the light of nature,’ although these remain, no longer suffice as the organ of signifying God’s will to man. A supernatural revelation has been necessary to reveal the law of duty, as well as to reveal the method of salvation through redemption.” ((A.A. Hodge, Evangelical Theology: Lectures on Doctrine (Carlisle, PA: The Banner of Truth Trust, [1890] 1990), 279.))
