Divine Command Theory

The basic claim

Divine command theory is a thesis about moral grounding. Many religious people are not divine command theorists — they hold moral truths are independent of God but that God reliably commands them. The DCT-er says something stronger: what makes an action right is that God commands it. Strip out God's commands and you strip out the rightness; replace them with different commands and rightness changes accordingly.

Three commitments unpack the view:

1. Constitutive dependence. Moral status (rightness, wrongness) is constituted by God's commands. The "because" runs from command to status.
2. Sufficiency. If God commands X, X is right. There is no further requirement for legitimacy.
3. Necessity. If X is right, God commands X. No moral facts float free of divine sanction.

The package is attractive to theists who want a non-arbitrary foundation that ties morality to a personal source of authority. It is also the easiest meta-ethical view for the average believer to articulate, even if its sophisticated defense requires considerable footwork.

Worked example: the Euthyphro dilemma

In Plato's dialogue, Socrates meets Euthyphro on the courthouse steps. Euthyphro is prosecuting his own father for murder. Socrates, perplexed, asks how Euthyphro is so confident he knows what is holy. Euthyphro answers: holy is what the gods love. Socrates presses with one question:

"Is the holy holy because the gods love it, or do the gods love it because it is holy?"

Translated for monotheism: is an act right because God commands it, or does God command it because it is right? Each horn is uncomfortable for DCT.

	Horn 1: right because commanded	Horn 2: commanded because right
What it says	God's commands constitute moral truth	Moral truth exists prior to God's commands
Who endorses it?	The DCT-er	Aquinas; secular realists; most theistic non-DCT-ers
Main worry	Arbitrariness — God could command torture, and it would be right	God isn't the source of morality; he just relays an independent standard
Theological cost	Threatens divine goodness — "God is good" becomes "God commands what God commands" (vacuous)	Threatens divine sovereignty — there's a standard above God
Standard reply	God's nature is essentially loving, so "God commands torture" is impossible	The standard isn't above God; it just is God's nature, which God doesn't choose
Net verdict	The arbitrariness can be softened, but at the cost of letting God's nature do the moral work	The sovereignty worry can be softened, but at the cost of not being a strict DCT

The dilemma is alive in part because each escape route compromises something a believer wants to keep. Choose the first horn straight, and you must concede that if God had commanded torture, torture would be right — a conclusion most theists won't accept. Choose the second, and you give up the distinctive claim that morality is grounded in God's commands.

Adams's modified divine command theory

Robert Adams's 1979 paper "A Modified Divine Command Theory of Ethical Wrongness" and his 1999 book Finite and Infinite Goods are the most influential 20th-century defense of DCT. Adams's strategy is precise.

• Restrict the thesis. Only deontic concepts (right, wrong, obligatory) are constituted by God's commands. Goodness — the property a loving God has — is not. Adams thereby allows that we can identify God's character as loving without that judgment depending on a prior command.
• Ground commands in nature. God is essentially loving. His commands flow from his loving nature, not from sheer will. So God's commanding cruelty for its own sake is not just unlikely — it is metaphysically impossible.
• Bite the rest of the bullet. Within the space of commands a loving God could issue, particular contents are constituted by the act of commanding. Whether to assign a specific Sabbath day, or specific dietary rules, can be a matter of God's choice within the bounds of his loving nature.

The arbitrariness horn is now defanged. "If God commanded torture, torture would be right" is treated as a counterpossible — a conditional with a metaphysically impossible antecedent. The vacuity charge against "God is good" is also defused, because goodness is grounded in God's loving nature, not in his commanding himself.

Critics like Wes Morriston push back: if God's nature is what does the work, why call this DCT at all? Adams's view starts to look like a sophisticated natural-law theory in which God's nature plays the role secular realists assign to mind-independent moral facts. The dispute between the views can come down to whether the work of grounding morality is done by command-acts or by underlying divine character.

Medieval voluntarism: Ockham vs Aquinas

The classical clash is between Aquinas (d. 1274) and William of Ockham (d. 1347).

Aquinas's natural law tradition (Summa Theologica I-II, qq. 90-97; see our Natural Law Theory article) holds that moral truths are necessary truths grounded in God's eternal nature. Even God could not make adultery good by commanding it; the wrongness of adultery flows from the human nature God created, not from arbitrary fiat. God's will and God's reason are coordinate; God doesn't decide what is good — he is goodness.

Ockham, writing seventy years later, pushed back with a strong voluntarism. The good is whatever God commands; God could in principle command anything. Ockham was clear that de potentia absoluta (by absolute power) God could command us to hate him, and the command would be obligatory. De potentia ordinata (by ordained power, i.e. given the order God has actually established) God reliably commands what tracks human flourishing, but this is contingent on God's choice.

Modern DCT inherits Ockham more than Aquinas. Adams's modified version is a partial retreat toward Aquinas — it gives God's nature a constitutive role — but it remains DCT in shape because the rightness/wrongness of specific acts depends on commands.

Counterarguments

The Euthyphro dilemma. Already covered. The arbitrariness horn is the most persistent worry; Adams's modification is the standard reply, but critics argue it shifts the grounding work to God's nature.

Epistemic access. If morality depends on God's commands, how do we learn what they are? Scripture, natural law, conscience, ecclesial tradition — each is contested. Disagreement among believers about specific commands looks epistemically similar to disagreement among secular ethicists, suggesting either source is fallible.

Atheist moral knowledge. Atheists routinely make sound moral judgments. If DCT is true, they are tracking divine commands without believing in them. That is consistent with sophisticated DCT (Adams allows it via general moral cognition), but it weakens the claim that DCT is the best explanation of moral knowledge.

The abrogation problem. Scripture contains commands that look prima facie horrendous (the herem-warfare passages in Joshua; the binding of Isaac). DCT has to either reinterpret them, treat them as historically contingent commands, or accept that loving-natured commands can include actions that look monstrous from outside. Each option costs something.

Wielenberg's challenge. Erik Wielenberg argues that even granting Adams's setup, it does no metaphysical work that secular non-naturalism (Enoch, Parfit) cannot do — both posit a non-natural foundation; the secular version doesn't carry the theological baggage.

Defender's reply. Adams and others argue DCT explains why moral demands carry the felt force of obligation: they are commands by an authority who knows you and loves you. A free-floating moral fact has nothing to grip the will; a personal command does. This advantage may or may not be enough to outweigh the costs.

Common confusions

• DCT is not "morality requires God to be obeyed." The thesis is constitutive: God's commands make actions right. Compatible variants might argue God doesn't issue commands at all but secures morality through providence; those aren't DCT.
• DCT is not the same as religious ethics. Most religious traditions have currents that treat moral truths as independent of divine command (Aquinas in Catholicism; many strands of Jewish ethics). DCT is one option among the religious-ethical menu, not its consensus.
• Adams's modification is not capitulation. Adams's view remains a real DCT — he holds rightness is constituted by God's commands. He just specifies that the commanding agent has a fixed loving nature, removing the worry that anything goes.
• The Euthyphro dilemma applies to monotheism cleanly. The original is about gods plural, but the structure transfers without change to monotheism. The substitution "God" for "the gods" loses no force.
• DCT is compatible with a wide range of normative ethics. A DCT-er can hold that God commands utilitarian or deontological or virtue-theoretic content. The view is meta-ethical (about what makes moral claims true), not first-order (about which moral claims are true).

Why it matters

• Most popular folk meta-ethics. A large fraction of laypeople, surveyed informally, articulate something like DCT when asked what makes morality binding.
• Theological stakes. The view shapes how religious traditions read their scriptures, train their clergy, and engage with secular ethics.
• Test bed for the Euthyphro. The dilemma is one of the oldest live arguments in philosophy; DCT is its natural home.
• Connection to political philosophy. Voluntarism shaped early modern accounts of sovereignty (Hobbes's "obligation comes from a commander") and of natural rights (Locke).
• Foil for secular meta-ethics. Realists, error theorists, and expressivists all sharpen their views by contrast with DCT's clean grounding story.
