This is an article of a scholastic nature, and it is quite complicated. I believe it adds value to much of the argument that has been taking place in the wider Lutheran circles for several decades now, and I present it as such: a scholastic offering, within its limitations. It is not a journal article exactly, but it is close to one.
Thesis: The law has at least three principles in classical Christian moral thought: revealing wrongdoing, restraining wrongdoing, and ordering social life.
The thesis grew out of three observations. First, laws do not make men righteous: law cannot turn appetite into virtue. Second, the English-language shorthand of curb, mirror, and guide, especially in the LCMS debates over the third use, has narrowed what the Formula of Concord actually says, until the law is heard almost only as accusation. Third, where churches neglect the instructional work of the law, they leave the ordering of common life to other powers: markets, entertainment, politics, and ideologies such as contemporary gender theory. The law that restrains and reveals also teaches, and what it teaches orders life among neighbors.
Stated this way, the thesis bears directly on the Lutheran controversy: the law is not merely an instrument for dealing with sin after it occurs. It also makes the good intelligible, establishes boundaries within which human beings may live, and teaches conduct appropriate to those who have been freed by Jesus Christ. The customary vocabulary—curb, mirror, and guide—is not false. But when those metaphors become substitutes for explaining what the law actually accomplishes, they can obscure the very doctrine they were intended to communicate.
The German of the Formula of Concord sharpens this point rather than overturning it. The third use orders the regenerate Christian’s ganzes Leben, his whole life, and a whole life is never lived alone. It is lived in marriage, household, congregation, work, and neighborhood. That is society. Civil government and its coercive discipline belong principally to the first use; but society is not government, and the ordering of Christian lives among neighbors is precisely the ordering of social life outside the state. That distinction makes the argument stronger, not weaker.
The first use restrains outward wrongdoing. The second reveals sin. The third directs the believer’s life toward the good. Together, they provide a richer account of how Christians understand moral order.
The three principles of the thesis are not offered as a replacement for the three uses. They resonate with them, overlapping at some points and distinct at others, and that overlap opens a way of speaking about the uses in which not every one of them must be heard as accusation.
I. The Epitome: What the German actually says
The opening of Article VI identifies three reasons for giving the law. The German phrases are remarkably concrete.
First use
äußerliche Zucht wider die Wilden, Ungehorsamen
External discipline against the unruly and disobedient.
Second use
zur Erkenntnis ihrer Sünden
Toward the recognition of their sins.
Third use
eine gewisse Regel hätten, nach welcher sie ihr ganzes Leben anstellen und regieren sollen
That they should have a definite rule according to which they ought to arrange and govern their entire lives.
These come directly from the German Epitome, Article VI, paragraph 1. Notice the verbs in the third formulation: anstellen and regieren. Regieren means to govern, direct, or rule. Anstellen, in this historical construction, concerns arranging, conducting, or ordering one’s life.
This is much more substantial than simply remembering a list of prohibitions. The law supplies a pattern according to which one’s entire manner of living can be conducted.
The English translation actually preserves much of this meaning. The difficulty is less a demonstrable mistranslation than the reduction of a comprehensive moral doctrine to the slogan the law is a guide. A guide to what? The German answers: to the ordering and governance of one’s entire life. And the text expressly places that responsibility upon regenerate people who still contend with the flesh.
II. The Solid Declaration: The third use is not theoretical
The Solid Declaration opens with essentially the same triad, but describes the third use more dynamically:
in dem Gesetz leben und wandeln
To live and walk in the law.
Article VI then explains that the Holy Spirit employs the written law to instruct believers concerning the good works in which they are to walk. The controversy was whether Christians, being renewed by the Spirit, still needed this instruction or whether their regenerated nature would spontaneously accomplish everything required. The confessors rejected the idea that Christians therefore had no further need to be taught by the law.
And here lies the remarkable connection to the observations with which this study began. The Formula distinguishes willing obedience from coerced obedience without separating either from the objective goodness commanded by God. It does not teach that the law creates the regenerated will. Indeed, the Solid Declaration, Article VI, paragraph 11, explicitly states that the law does not give the power to accomplish the new life it commands. That power comes through the Holy Spirit and the Gospel.
Consequently:
Restraint can govern conduct without transforming the heart.
Revelation can expose sin without healing the sinner.
Instruction can disclose the shape of righteous living without itself supplying the power to love righteousness.
And that brings us directly back to the original observation. Laws do not make men righteous. The Formula agrees. But it does not conclude that the law is therefore useless in forming the outward conditions and moral understanding within which righteous conduct can occur.
III. The overlooked distinction: The law’s content and the law’s effect
This is where the thesis cuts most effectively. A recurring difficulty in these debates is that theologians can confuse three different questions.
What does the law command? The eternal will of God concerning human conduct.
What does the law accomplish? It restrains outward wickedness, reveals sin, and teaches the pattern of good conduct.
What does the hearer do with it? The unregenerate may obey unwillingly; the regenerate, insofar as renewed by the Spirit, obey willingly.
The Epitome, Article VI, paragraph 7, makes the third distinction explicit. There remains one immutable divine law; the difference lies in the person obeying it. That is crucial. We do not have three different laws. Nor must we suppose that the same passage of Scripture can perform only one use at a time.
The command against theft can restrain a thief through threatened punishment, reveal the covetousness of the believer, and teach that believer to protect his neighbor’s property. The difference is not necessarily the wording of the commandment. It is the relationship between the command, the hearer, and the work being accomplished.
And there is something even more revealing in the German of Solid Declaration VI, paragraph 17:
aus freiem lustigem Geist
From a free, glad, willing spirit.
This describes the regenerate person’s obedience—not obedience extorted through fear, but conduct flowing from the Spirit’s renewal. That expression deserves far more attention than the mechanical vocabulary of curb, mirror, and guide. It reconnects the third use to Christian liberty. A law that reveals the goodness of a deed is not necessarily enslaving the person who freely delights in doing it.
IV. The English-language LCMS controversy
The criticism of the LCMS debate has an identifiable historical basis. In 2005, Lawrence R. Rast Jr. described continuing divisions within American Lutheranism, including the LCMS, about the third use. The controversy involved interpretations of Luther, confessional subscription, justification, and sanctification. The argument remained active twenty years later.
In a 2025 article in Concordia Theological Quarterly, Gifford A. Grobien, of Concordia Theological Seminary, Fort Wayne, examined precisely the question of whether the third use is anything more than the second use applied to Christians. His article is titled Overlooked Aspects of the Third Use of the Law. Grobien identifies a central question: does the law only accuse the Christian of sin, or does it also teach what holiness and good works actually are? He argues that Article VI presents a broader, multifaceted account of the law’s operation in Christian life. This is strikingly close to the concern raised here.
However, the documentary evidence does not establish that English mistranslation caused the controversy. German-speaking Lutheranism also experienced antinomian disputes; indeed, Article VI was written to settle one. The more defensible criticism is that some English-language theological shorthand permits a functional narrowing of the confessional text.
In particular, if every encounter between the Christian and the law is reduced to accusation, the instructional dimension becomes difficult to articulate without appearing to compromise the Gospel. The believer is then told what is wrong but may receive insufficient instruction in what is good. That problem cannot be solved simply by repeating that the law is a guide. One must explain what is being guided, toward what end, and by what power.
V. The political consequence: Who orders social life?
This is where the thesis becomes a larger work of Christian moral philosophy. Every society has norms governing permissible conduct, obligations, duties, relationships, property, and the protection of the vulnerable. If Christian communities neglect moral formation, those practices do not remain unformed. Other institutions, economic incentives, entertainment systems, political movements, and customary expectations continue shaping them.
The question is not whether human life will be ordered. The question is which understanding of the good will inform that order.
Yet the distinction between the three uses must remain precise. Civil legislation principally concerns external conduct. It can prohibit assault, punish fraud, and regulate commercial relationships. It cannot produce inward faith or Christian regeneration. The third use principally concerns those who have received the Gospel. They learn from God’s law how to conduct their lives and fulfill their vocations. Those vocations include marriage, fatherhood, motherhood, work, citizenship, hospitality, commerce, and care for neighbors. Consequently, the third use has social consequences even though it is not identical with civil legislation.
This is the bridge this formulation begins to construct.
The law’s principle of restraint provides boundaries for a society containing unrighteous people.
Its principle of revelation exposes the wrongdoing that both institutions and individuals may normalize.
Its principle of order teaches Christians how to act positively within their vocations.
Neither public order nor Christian ethics can be reduced to prohibitions alone. The law’s instructional role helps Christians assess the goods of human life. Practical institutional design then requires judgment about consequences, incentives, justice, and human freedom.
This also offers a more exact way to examine the criticism of contemporary gender ideology: rather than assuming that every social development belongs to one ideological source, we can ask which moral anthropology its institutions presuppose, which behaviors they reward, and whether their standards are applied consistently to men and women. That is a testable critique rather than a merely rhetorical one.
VI. The deepest passage: The law does not create the good it commands
Return to Solid Declaration VI, paragraphs 11–12. The law identifies the new life, but does not provide the power to accomplish it. The Holy Spirit, received through the Gospel, renews the heart and employs the law to teach the believer.
This distinction resolves an apparent contradiction. If the law cannot produce righteousness, why teach it to the righteous? Because revealing what is good and generating the capacity to love that good are different operations.
The law makes the form of righteous conduct intelligible. The Gospel announces Jesus Christ, in whom righteousness, forgiveness, and new life are given. The Holy Spirit renews the believer, who learns to walk according to the will of God.
This also makes sense of the Solid Declaration’s remarkable statement that Christians are not under the law but live in the law. The German of paragraph 18 preserves the contrast:
nicht unter, sondern im Gesetz
Not under, but in the law.
Here the thesis reaches beyond the usual three metaphors. For the Christian, the moral law is not simply an external barrier, a source of accusation, or a manual of instructions. It is the expression of the divine will within which renewed human life is meant to flourish.
One might say:
The law reveals the order of the good. The Gospel gives what the law cannot give. The Spirit teaches the redeemed to walk freely within that order.
That is not a fourth use of the law. It is a synthesis of the confessional distinctions.
VII. A refined thesis
The thesis is sharpened by a rigorous reading of the German.
Original thesis
The law has at least three principles in classical Christian moral thought: revealing wrongdoing, restraining wrongdoing, and ordering social life.
The thesis read alongside the Confession
The divine law restrains wrongdoing, reveals sin, and instructs the ordering of human life according to God’s immutable will. Its restraining use establishes outward discipline; its revealing use exposes the sinner’s condition; and its instructional use teaches the regenerate how to live and walk in righteousness. The law neither creates faith nor supplies the power of obedience. That belongs to Jesus Christ through the Gospel and the renewing work of the Holy Spirit. Yet the regenerate, living freely according to God’s will, give concrete expression to that instruction through their personal, familial, ecclesiastical, and civic vocations.
The immediate advantage is that the three principles and the three uses can now be read side by side, as actions with distinct objects.
The law restrains conduct.
The law reveals sin.
The law instructs life.
And Christian life, necessarily lived among neighbors, participates in the ordering of society.
VIII. The deeper discovery: Ordering without manufacturing righteousness
This study began with the observation that law cannot transform appetite into virtue. This is not an embarrassment for the third use. It explains why the distinction exists.
A Christian society cannot presume that civil restrictions will regenerate its citizens. Neither can a church presume that preaching forgiveness makes instruction about righteous conduct unnecessary. And neither may confuse Christian freedom with the absence of moral form.
Consider Christian freedom: the capacity to offer love without anticipating rejection and to obey Jesus Christ without treating obedience as a mechanism for purchasing divine acceptance. The law can illuminate what loving conduct requires. It cannot create the inward freedom through which love becomes spontaneous. But because that freedom is the fruit of the Spirit, the law remains useful as instruction without becoming the source of salvation.
Here the Formula of Concord possesses more wisdom than the customary shorthand communicates. The Christian does not become free by escaping the good. The Christian becomes free to love the good without being driven by terror.
The thesis can be put more economically still:
Law restrains evil, reveals evil, and teaches good.
That is the Occam’s razor: not a new set of uses, but an economical way of hearing the old ones. It keeps the objective character of God’s commandments, identifies the distinct operations of the law, and preserves the priority of Jesus Christ in creating the new life.
It also points toward a substantial further question for Lutheran political theology: how does a church that understands the distinction between civil restraint and spiritual renewal positively instruct Christians to exercise wisdom in organizing their shared lives? That question can be answered without confusing the Church with the state, the Gospel with legislation, or outward discipline with salvation. And it is precisely where the critique of institutional passivity becomes most consequential.
