Theonomy, from the Greek theos (God) and nomos (law), is the belief that biblical law—particularly the civil laws of the Old Testament—should be applied in contemporary society, including modern governments. It’s a theological position that continues to spark debate, particularly within Reformed and evangelical circles.
What Is Theonomy?
At its core, Theonomy argues that God’s law, as revealed in Scripture, is morally binding on all people and all nations, not just ancient Israel. While many Christians affirm the moral authority of the Ten Commandments, Theonomists take this further, advocating that even the judicial laws given to ancient Israel have ongoing validity—unless explicitly abrogated by the New Testament.
Theonomy is distinct from theocracy, in that it doesn’t necessarily advocate for rule by clergy. Rather, it seeks for civil governments to be informed by God’s revealed standards of justice.
Key Thinkers and Origins
The Theonomic movement emerged in the mid-20th century, rooted in Reformed theology and drawing heavily on Presbyterian confessionalism. The central figure behind modern Theonomy is:
- Rousas John Rushdoony – Often considered the father of Christian Reconstructionism, Rushdoony argued that society should be rebuilt on biblical law. His massive work, The Institutes of Biblical Law (1973), became foundational to the movement.
Other influential Theonomists include:
- Greg Bahnsen – A gifted apologist and theologian, Bahnsen defended Theonomy with scholarly rigor. His book Theonomy in Christian Ethics (1977) laid out a formal case for applying biblical law today.
- Gary North – Rushdoony’s son-in-law, an economist who extended Theonomic thought into areas like economics and politics. He was particularly known for arguing that biblical law provides a blueprint for a just and free society.
These thinkers are often associated with Christian Reconstructionism, a broader movement that seeks the transformation of all life—including civil society—under the lordship of Christ.
Core Beliefs of Theonomy
- Continuity of Old Testament Law – The judicial/civil laws given to Israel continue to be morally binding unless specifically changed in the New Testament.
- Limited Role of Government – Civil governments should uphold justice as defined by Scripture, not based on humanistic or secular values.
- Opposition to Secularism – Theonomy rejects the separation of law and religion, seeing God’s law as the only valid basis for justice.
- Moral Absolutes – Theonomy holds that laws cannot be based on cultural consensus but on God’s unchanging moral standards.
Critics and Controversy
Theonomy has faced strong criticism from both within and outside Reformed circles. Critics argue that:
- It misapplies Old Testament laws, which were meant for Israel under the Old Covenant.
- It risks legalism and could foster religious oppression.
- It confuses the distinct roles of church and state in the New Covenant.
- It neglects the historical and redemptive context of the Mosaic law.
Even among conservative Christians, many reject Theonomy as inconsistent with New Testament teachings on grace, liberty, and the Kingdom of God.
Theonomy Today
The height of Theonomy’s influence was in the 1980s and 1990s, but its ideas continue to resurface today, particularly among those concerned with the erosion of Christian influence in the public square. In recent years, we’ve seen renewed interest in the movement among:
- Some in the Reformed homeschooling and Christian education communities
- Individuals in Christian nationalism circles
- Certain online ministries and podcasts that revisit the teachings of Bahnsen and Rushdoony
Names like Joel McDurmon and Theonomy Resources have sought to update and reinterpret Theonomy for a modern audience, sometimes modifying earlier views (e.g., McDurmon has since distanced himself from some Reconstructionist positions).
Where Is Theonomy Heading?
Theonomy remains a minority position within Christian theology, but it’s gaining fresh attention in an age where questions of law, morality, and culture are increasingly polarized. Whether one agrees or not, the Theonomic vision offers a challenge to modern Christians: How should God’s Word shape society, not just the church?
