How Should Christians Read Biblical Criminal Law?

Before we examine homicide, witnesses, juries, pretrial detention, punishment, restitution, prison, or Paul standing before Roman officials, we need to establish the rules of the investigation.

Because the Bible contains a great deal of law.

Some of it feels immediately familiar.

Do not murder. Do not steal. Do not bear false witness. Judge impartially.

Other parts feel much less familiar.

Build a parapet around your roof. Establish cities of refuge. Return a poor man’s cloak before sunset. Require multiple witnesses. Punish certain offenses in ways modern states usually do not.

So what are Christians supposed to do with all of that?

That question matters because this series is about “the Bible and the ideas behind American criminal justice.” If we do not answer the interpretive question first, we will almost certainly mishandle the legal question later.

Two bad shortcuts

There are two common mistakes.

The first says:

“That was Old Testament Israel. We are not Israel. None of it matters now.”

That approach solves the problem by ignoring large portions of biblical law.

The second says:

“God commanded Israel to do this, therefore modern governments should adopt the same statute and the same penalty.”

That approach solves the problem by flattening the differences between ancient Israel and a modern constitutional republic.

Both are too simple.

The Reformed tradition gives us a better framework.

The Westminster approach

The Westminster Confession distinguishes between the moral law, the ceremonial laws, and the judicial laws given to Israel.

The moral law reflects God’s enduring righteousness and is summarily comprehended in the Ten Commandments.

The ceremonial laws pointed forward to Christ and were fulfilled in Him.

The judicial laws governed Israel as a particular body politic—a real covenant nation with courts, penalties, officials, property rules, and public institutions.

And here is the key point:

Those judicial laws expired with Israel as a political commonwealth, except insofar as their “general equity” still applies.

That phrase—general equity—is the controlling idea for this entire series.

What is general equity?

In plain English, general equity means this:

The specific legal form may belong to ancient Israel, while the enduring principle of justice underneath it may still teach us something now.

In other words, we must distinguish between:

1. the form of the law, and
2. the moral principle the law was expressing.

That distinction matters a great deal.

Take Deuteronomy 22:8. It says that when a man builds a new house, he should make a parapet around the roof so that he does not bring bloodguilt on his house if someone falls from it.

Now, if we read that woodenly, we might say:

“Every faithful Christian home must have a low wall around the roof.”

But that is not the point.

The point is that if you create or control a foreseeable danger, you bear responsibility to take reasonable steps to protect human life.

In ancient Israel, that took the form of a parapet around a flat roof used as living space.

In modern America, that principle may show up in stair railings, guardrails, fencing, building codes, workplace safety rules, and similar protections.

Different form.

Same underlying concern.

That is general equity.

Why this matters for criminal justice

This method becomes even more important when we start discussing criminal law.

Suppose Scripture requires multiple witnesses in a serious matter. Our first question is not merely:

“Must every modern criminal case look exactly like that text?”

We should ask:

What danger was this rule addressing? False accusation? Uncorroborated testimony? Abuse of state power? The possibility of condemning the innocent?

Then we ask:

What enduring principle of justice does the rule reflect? How does the rest of Scripture treat that principle? How has the Reformed tradition understood it? And how might a modern legal system express that same concern differently?

The same method applies to questions like:

• murder versus accidental killing,
• cities of refuge,
• judicial impartiality,
• false testimony,
• proportionate punishment,
• restitution,
• and the rights of the accused.

This series will therefore distinguish between biblical principle and modern mechanism.

They are not always the same thing.

Ancient Israel is not America

That should be obvious, but it still needs to be said.

Ancient Israel was a covenant nation directly governed under God’s revealed law within a unique redemptive-historical framework.

America is not that.

The United States is a constitutional republic shaped by many influences, including English common law, classical thought, Enlightenment ideas, Protestant theology, and biblical morality.

So I am not going to argue that Moses wrote the American criminal code.

He didn’t.

Nor am I going to pretend that a city of refuge is the same thing as the modern bail system, or that the congregation in Numbers is identical to an American jury, or that Roman procedure in Acts is the same thing as the Sixth Amendment.

Those would be careless arguments.

Instead, I want to ask a better question:

What principles of justice does Scripture reveal, and where do we see similar concerns arise in later legal systems?

That is a far more responsible investigation.

The Calvinistic lens matters here

Because this is being done self-consciously from a Reformed and PCA perspective, there are at least four theological convictions that must stay in view.

First, human beings are fallen.

That includes criminals. It also includes police officers, prosecutors, defense attorneys, witnesses, judges, jurors, and lawmakers.

No office removes sin.

That is one reason due process, evidence, corroboration, judicial review, and restraints on state power matter so much.

We do not build justice on the assumption that some class of people becomes morally safe once they hold authority.

Second, human beings bear the image of God.

That means the victim matters. The accused matters. The guilty matter. The wrongly accused matter.

A biblical vision of justice never asks us to choose between accountability and human dignity. It requires both.

Third, the magistrate has a legitimate God-given role.

Romans 13 does not present civil authority as inherently evil. The state bears the sword for a reason. Public justice is real. Crime is real. Protection of the innocent is real.

A Christian view of criminal justice is not anti-government.

Fourth, the state is not the church.

The civil magistrate bears the sword. The church holds the keys. The courthouse cannot redeem sinners. It can restrain evil, punish wrongdoing, and preserve order. But it cannot regenerate the human heart.

That distinction will matter more and more as the series unfolds.

What this series is—and is not

This series is not:

• an argument that every Old Testament penalty should become modern law,
• an argument that America is simply ancient Israel in modern dress,
• or an argument that the Bible contains a fully developed American criminal-justice system.

This series is:

• an exploration of biblical justice,
• a comparison of enduring principles with modern legal practices,
• a Reformed reflection on crime, punishment, evidence, authority, and human dignity,
• and an invitation to ask whether our current system reflects genuine justice as well as we often assume.

The method we will use

Every lesson in *Before the Courthouse* will move through the same basic structure:

THE CASE We begin with a biblical legal issue or narrative.

THE LAW What does the text actually say?

THE REFORMED LENS How should we understand it through Scripture, general equity, and the Reformed confessional tradition?

THE COURTHOUSE What modern criminal-justice question or institution addresses the same problem?

THE QUESTION What should the reader now ask about our own system?

That framework will help us stay organized and honest.

Why begin here?

Because the next lessons are going to make much bigger claims.

We are going to ask whether the Bible distinguishes murder from accidental killing based on intent.

We are going to ask whether cities of refuge moved justice away from private vengeance and toward public process.

We are going to ask whether community adjudication in Numbers bears any resemblance to the idea behind the jury.

We are going to ask whether false-witness laws have something to say to police reports, affidavits, testimony, and wrongful convictions.

We are going to ask whether Paul’s treatment by Roman officials raises questions about due process, religious persecution, pretrial punishment, and appeal.

We are going to ask whether restitution has been crowded out by incarceration.

And eventually we are going to ask why prison became America’s default answer to crime.

Those are serious questions.

But before we ask what biblical criminal law can teach us, we need to know how Christians are supposed to read biblical criminal law in the first place.

That is why Lesson 0 comes first.

The judicial laws of Israel no longer bind modern nations as a civil code. But their general equity still teaches us. The ancient form may pass away. The principle of justice may remain.

That is where *Before the Courthouse* begins.

Next lesson: Lesson 1 — The Sword Can Be Just

Does government have a God-given right to use force in the cause of justice?

Romans 13 says yes.

But if fallen human beings need the sword, what restrains the fallen human beings who hold it?

That is where we go next.
