What about capital punishment?

Question 12005

Capital punishment is one of those questions where sincere believers land in different places, and I want to say that plainly before I say anything else. Nobody should be treated as a heretic for wrestling with it. But this is not a question Scripture leaves untouched, and my concern is that we listen to what God has said rather than absorbing whatever the culture around us happens to feel this decade.

I have sat with people on both sides of this. Some cannot stomach the thought of the state taking a life. Others cannot stomach the thought of a murderer walking free. Both instincts have something honest in them. So let us go to the text and see what actually holds up.

Where capital punishment begins in Scripture

The foundation is Genesis 9:6: “Whoever sheds the blood of man, by man shall his blood be shed, for God made man in his own image.” Notice what that verse does not say. It does not appeal to deterrence. It does not appeal to public safety or the cost of imprisonment. It grounds the penalty in the identity of the victim. A human being is an image-bearer of the living God, and to destroy one deliberately is to strike at something that carries God’s own likeness.

The timing of that verse matters as much as its content. It is given to Noah, centuries before Sinai. It belongs to the arrangement God established with all humanity after the Flood, not to the covenant He later made with one nation. That distinction is the hinge on which most of the argument turns, and I think it is often missed.

Why the Mosaic law does not settle it either way

The law given at Sinai widened the death penalty considerably. Blasphemy, adultery, persistent rebellion and sabbath-breaking all carried it within the theocratic nation of Israel. Anyone who wants to argue from those texts to modern statute books has to explain how a nation that was governed directly by God, with the tabernacle at its centre, maps onto a secular parliament in the twenty-first century. It does not.

The believer is not under the Mosaic law as a covenant (Romans 6:14; Galatians 3:24-25). Those specific applications belonged to Israel under an arrangement that has passed. But this cuts both ways. Abolitionists sometimes point to the Mosaic excesses in order to discredit the death penalty altogether, and that argument proves too much, because Genesis 9 sits outside that covenant entirely and has never been withdrawn.

The state and the sword

Paul writes that the governing authority “does not bear the sword in vain” and is “the servant of God, an avenger who carries out God’s wrath on the wrongdoer” (Romans 13:4). The sword in that sentence is not a ceremonial prop. In the Roman world it was the instrument of execution, and Paul’s readers in Rome would not have needed that explained to them. The Greek word is machaira, an ordinary blade used for ordinary killing.

Paul was writing under Nero. He knew perfectly well that governments abuse the power they hold, and he still described the authority to punish as delegated by God. That is a striking thing to write from inside an empire that would eventually execute him. It tells me the principle does not depend on the moral quality of the particular government exercising it.

There is a further detail worth noticing. Paul himself, standing before Festus, said that “if I am a wrongdoer and have committed anything for which I deserve to die, I do not seek to escape death” (Acts 25:11). He did not deny that some crimes carry that weight. He denied that he had committed one.

What about the woman caught in adultery?

This is the passage people reach for most quickly, and it deserves an honest answer. In John 8:1-11, Jesus refuses to join the stoning and tells the woman to go and sin no more. But look at who is present and who is absent. There is no husband, no second offender, no witnesses willing to testify under oath. The men holding the stones are not a court. They are a mob using a woman as bait in a trap set for Jesus.

Jesus does not abolish the penalty. He exposes the hypocrisy of men who wanted a conviction without justice. If anything, the episode is a warning about how easily the machinery of punishment is bent to serve other purposes, which is exactly the concern any thoughtful supporter of the death penalty ought to carry.

Justice is not the same thing as vengeance

Here is where I want to press on my own side of the argument. The moment a Christian starts to enjoy an execution, something has gone badly wrong in the heart. Scripture is clear that God takes no pleasure in the death of the wicked (Ezekiel 33:11), and if He does not, we have no business doing so.

Capital punishment, biblically understood, is a sober act of justice performed by an authority acting on God’s behalf. It is not catharsis for the public. It is not a way of processing grief. The moment it becomes entertainment, or a proxy for political tribalism, it has stopped being the thing Scripture describes.

The problem of getting it wrong

The strongest practical objection is not theological but procedural. Innocent people have been convicted. Poor defendants receive worse representation than wealthy ones. Racial disparities in sentencing are documented and real. None of that touches the principle, but all of it touches the practice, and a Christian who supports the principle has an obligation to care fiercely about the practice.

The Mosaic law itself built in safeguards that modern systems would do well to imitate. No one could be put to death on the testimony of a single witness (Deuteronomy 17:6), and a witness who lied in a capital case bore the penalty he had sought for the accused (Deuteronomy 19:16-21). God’s own legislation treated the possibility of judicial murder as a horror to be guarded against with everything available.

So I hold the principle and I hold the caution together. Where the standard of evidence cannot be met, where the process is corrupted, where the system demonstrably fails the poor, the Christian voice should be raised loudly. That is not a retreat from the biblical position. It is what taking the biblical position seriously actually looks like.

Mercy, repentance and the cross

One more thing needs saying, because it is the thing most likely to be forgotten in a debate about statute. The thief on the cross was justly condemned by his own admission, and he entered paradise that same day (Luke 23:41-43). A death sentence is not a verdict on eternity. Some of the most remarkable conversions I have read about happened in condemned cells.

That is why the church’s interest in the condemned should never be limited to arguing about their sentence. If we believe what we say we believe about the gospel, then a man with a date fixed for his execution is precisely the man who most urgently needs to hear it. I have never been able to reconcile a hunger for punishment with a hunger for souls, and I do not think Scripture asks me to.

Deterrence, statistics and the wrong argument

A great deal of public debate about capital punishment turns on whether it deters. Studies are produced, contested, revised and produced again. I follow the argument with interest, but I do not think a Christian case can be built on it, and I would be uneasy if it could.

Genesis 9 does not say a word about deterrence. The reason given for the penalty is the image of God in the victim, which means the argument is about justice rather than social outcomes. If deterrence were the ground, then a study showing no deterrent effect would abolish the penalty overnight, and a study showing a strong effect would justify executing people for far lesser crimes. Neither conclusion is one Scripture would tolerate.

This is why I want Christians arguing about capital punishment on biblical ground rather than borrowed ground. Once we start defending a scriptural position with pragmatic reasoning, we have quietly conceded that pragmatism is the real authority, and we will lose the next argument as soon as the numbers change.

So, now what?

So where does that leave us? The case for capital punishment rests on the image of God in the victim and the God-given authority of the state to administer justice. It is not a hangover from a harsher age, and it is not a Mosaic relic. It comes from a pre-Mosaic word to Noah that has never been rescinded, and it is echoed by Paul writing under an emperor who would one day kill him.

Hold it soberly, then. Argue for scrupulous evidence and honest process. Refuse the spirit of vengeance that so easily attaches itself to this subject. And do not let a debate about the state’s sword distract you from the mercy of God, which reaches into the cell and the courtroom alike. If you want to think further about how we reason through questions like this, you might find how we make moral decisions helpful, along with the related question of self-defence and what Scripture says about war. What would change in your own thinking if you started, as Genesis does, with the worth of the person who was killed?

“Whoever sheds the blood of man, by man shall his blood be shed, for God made man in his own image.”
