Divine command ethics

— The rules of the LORD are true, and righteous altogether. Psalm 19:9

Definition

Divine command ethics (or divine command theory) is the view that an act’s moral rightness or wrongness consists in God commanding or forbidding it. Taken as the whole of the theory, moral obligation reduces to a bare decree: God could have commanded the opposite of what he did, and it would have been equally right. Reformed theology rejects that reduction. God’s commands are not arbitrary; they express his own unchanging character, so that an act is required not merely because God happens to will it, but because his willing it flows from who he already and unchangeably is.

Confessional Definition

The 1689 Second London Baptist Confession of Faith has no chapter devoted to moral philosophy, but its opening description of God supplies the ground the question depends on. God is “infinite in being and perfection… immutable… most just and terrible in his judgments, hating all sin.”1 His justice and his hatred of sin are given as features of what he is, not as decisions that could just as easily have gone the other way.

The confession’s chapter “Of the Law of God” applies the same principle to the moral law itself. Rather than presenting the Ten Commandments as a rule Israel happened to receive at Sinai, it locates them in creation: God gave Adam “a law of universal obedience written in his heart,”2 which “continued to be a perfect rule of righteousness after the fall.”3 A law built into human nature from the start, on this reading, is not the kind of rule a strict divine command theory requires — one that could have been reversed by a different decree without any change in God himself.

Biblical Basis

Scripture treats God’s own commands as already true and right, not merely as impositions to be obeyed regardless of their content: “the law of the LORD is perfect… the rules of the LORD are true, and righteous altogether” (Ps. 19:7, 9). Israel is told that keeping God’s statutes “will be our righteousness” (Deut. 6:24-25) — language that treats obedience as conformity to something rightly called righteous, not merely as compliance with a sovereign’s preference. When Christ sums up “the Law and the Prophets” in the two commands to love God and neighbor (Matt. 22:37-40), he is not trading many arbitrary rules for one arbitrary rule; he is naming the single character trait the whole law had been expressing all along. John draws the same connection from the other direction: “God is love” (1 John 4:8) states what God is, not merely what he happens to prefer, which is why the next clause follows as a matter of course — “whoever does not love does not know God.”

Historical Development

The tendency to reduce morality to a bare decree has a specific history. Late medieval nominalism pressed God’s freedom so far that his will came unmoored from his own reason and character. Craig Carter’s account of this shift, quoting historian Michael Allen Gillespie, describes its result as a “capricious God, fearsome in his power, unknowable, unpredictable, unconstrained by nature and reason, and indifferent to good and evil.”4 On that view, an act’s rightness would depend on nothing but the fact that God happened to command it, and could have gone the other way just as easily.

Reformed theology has consistently rejected this account, on grounds that reach beyond ethics alone: God’s will “is not capricious,” not because anything outside God constrains it, but because his willing already flows from who he is.5 Applied specifically to morality, the same rejection appears in Charles Hodge’s statement that “moral good is good in its own nature, and not because of its tendencies, or because of its conformity to the laws of reason,” paired with the claim that “all law has its foundation in the nature and will of God.”6 Taken together, these two principles rule out both a Kantian account that grounds moral norms in reason alone, apart from God, and a strict divine command account that grounds them in will alone, apart from God’s own nature.

Opposing Views

Not every account of ethics that treats morality as objective and universally binding grounds it in God’s commands. Kant’s deontology holds that duty is discovered by reason rather than revelation: an act is right when it accords with a maxim the agent could rationally will to become a universal law, with no appeal to what God has commanded.7 This is a genuine rival to divine command ethics, not merely a variation on it, since it locates the standard of right and wrong in reason alone, even while agreeing with divine command ethics that moral obligation is objective rather than a matter of preference.

Consequentialism rejects command-based ethics from a different direction. Rather than asking what has been commanded or what accords with a universal principle, it asks “what will most likely produce the greatest good for the greatest number of people.”7 On this view, even an act Scripture forbids could in principle be justified by a sufficiently good outcome — the reverse of an ethic in which God’s command itself settles the question.

Objections and Responses

If a divine command makes an act right, could God just as easily have commanded its opposite — cruelty rather than love, say — making cruelty right instead? Not on the confessional answer, because it denies the premise. Commands do not float free of God’s own character: the seventh commandment “is not merely an arbitrary statement of the divine will… so that God could just as easily have given a command to commit adultery. Rather, it is grounded in God’s nature.”7 The same reasoning generalizes to the whole moral law: because it is written into human nature at creation rather than issued as a free-floating decree, only a change in God’s own unchanging character — which cannot happen — could have made him command differently.

But if morality is grounded in God’s nature rather than his commands, doesn’t that put a standard above God, one he has to conform to? Only if God’s nature were something other than God. Moral good “is good in its own nature,” and “all law has its foundation in the nature and will of God”6 — God’s character is not a rule he consults or a rule he invented, but simply who he is. Because God and God’s nature are not two things, there is no external standard for goodness to be grounded in; the ground is God himself. This is also why some of God’s commands could be temporary in a way the moral law given at creation is not: laws “founded… upon the relations of men in the present state of existence,” such as the Mosaic permission of polygamy or the Levirate marriage law, could be set aside once their occasion passed, while laws “founded… on the immutable nature of God” could not be.8 What changes is which precepts express God’s unchanging character for a given people at a given time, not the character itself.
