[There has been some online discussion of Luther and nominalism in the aftermath of Jay Dyer’s interview on Tucker Carlson, here: https://www.youtube.com/watch?v=8-VqMQHz54k. This is a response.]
Luther and Nominalism: A Complicated Relationship
The claim that Martin Luther was a philosophical nominalist carries a surface plausibility, rooted primarily in his doctrine of justification by faith alone. According to this view, God “names” or declares sinners righteous by a sheer act of divine will, even though they remain sinners in themselves. This “simultaneously justified and sinful” doctrine stands in sharp contrast to the medieval Roman Catholic teaching that justification requires an actual infusion of righteousness before God can declare a person just. The emphasis on divine declaration, detached from immediate ontological transformation, seems to echo nominalist metaphysics, in which God’s will can impose names or categories without corresponding realities in the created order.
Yet this interpretation is ultimately misleading. It is true that Luther was trained in the scholastic nominalism that was popular in his time. But he did not uncritically adopt nominalism, and in fact reacted against it in various ways. A closer examination of Luther’s thought reveals significant counter-evidence that either refutes the charge outright or, at minimum, greatly complicates any straightforward link between the Reformer and nominalism.
Luther’s Suspicion of Philosophy
First, Luther was notoriously unphilosophical—and at times overtly anti-philosophical. His central concern was that philosophy tends to exalt autonomous human reason above the authority of Scripture. The gospel, after all, is “foolishness to those who are perishing” (1 Corinthians 1:18). Luther did not reject reason wholesale; he insisted that it must be subordinated to faith and the Word of God. Human wisdom had subjected the “foolishness” of the cross to its own distorting categories, producing a theology more Aristotelian than apostolic.
This conviction appears forcefully in Luther’s early work. His 1517 Disputation Against Scholastic Theology—a kind of prelude to the Ninety-Five Theses—directly assaulted the integration of Aristotelian philosophy into Christian doctrine. Among its theses we find:
Thesis 41: “Virtually the entire Ethics of Aristotle is the worst enemy of grace.”
Thesis 43: “It is an error to say that no man can become a theologian without Aristotle.”
Thesis 50: “Briefly, the whole Aristotle is to theology as darkness is to light.”
In his Table Talk, Luther’s critique grew even sharper: “Reason is a whore, the greatest enemy that faith has; it never comes to the aid of spiritual things, but more frequently than not struggles against the divine Word.” He famously called philosophy “the Devil’s whore.” These statements reflect not a nominalist philosopher at work, but a theologian determined to let Scripture judge every human system. Reason, rightly used as a servant of faith, has its place; as an autonomous authority, it is a dangerous idol.
Realist Elements in Luther’s Theology
Second, important strands of Luther’s theology are positively anti-nominalist. He affirmed natural law, which presupposes a created order with fixed essences and a shared human nature. “All men have a certain natural knowledge implanted in their minds,” he wrote, “whereby they naturally perceive that they ought to do unto others as they would have others do unto them. These and other such opinions, which we call the natural law, are the foundation of human right and of all good works.” Such statements assume real universals and objective moral structures grounded in creation, not arbitrary divine naming. In particular, Luther’s view of the sexes was very much rooted in nature, that is, God’s creational design. Even though Luther believed that all the baptized share in a common priesthood, he held that wives are to be in subjection to their husbands and women cannot hold pastoral office, as matters of propriety and good order in the family and in the church.
Even more telling is Luther’s doctrine of the Lord’s Supper. He insisted on the real presence of Christ “in, with, and under” the bread and wine. The elements are not merely named Christ’s body and blood as empty symbols; they truly convey Christ’s body and blood to the believer. While Luther rejected the Aristotelian metaphysics underlying transubstantiation, his position remained realist rather than nominalist. The sacrament effects a genuine participation in Christ, not a linguistic fiction.
Justification: Not a Legal Fiction
Third, and most decisively, Luther’s mature doctrine of justification is not actually nominalist, nor is it a “legal fiction” in the dismissive sense often alleged. It is true that Luther taught believers are declared righteous by faith even while they remain sinners in themselves—simul iustus et peccator. Yet this doctrine is no arbitrary divine whim; it is a direct echo of Scripture: “God justifies the ungodly” (Romans 4:5) and “calls things that are not as though they were” (Romans 4:17).
Luther had indeed been shaped by the nominalist tradition of his education, particularly the teaching of Gabriel Biel, but he reacted vigorously against its semi-Pelagian tendencies. His positive doctrine of justification transcends nominalism through the believer’s union with Christ. Faith does more than receive a bare declaration; it unites the soul to Christ as a bride is united to her bridegroom. In this “happy exchange,” Christ takes the believer’s sin and bestows His own righteousness. As Luther beautifully expressed it:
“Faith not only justifies, it unites the soul with Christ as a bride is united with her bridegroom. At this point, a contest of happy exchanges takes place… Christ, the rich, noble, and good bridegroom takes the poor, despised, wicked little harlot in marriage, sets her free from the devil and all evil, and decks her out with all sorts of good things.”
The righteousness by which the believer is justified is alien in the sense that it is not native to us, but it is nevertheless truly ours because we possess Christ by faith and therefore possess all that is His. God’s declaration is no mere name; it is a reality grounded in our mystical union with the risen Christ. We really are righteous in Him, legally and covenantally.
Of course, this declared righteousness is inseparable from the practical righteousness of a transformed life. The same faith that unites us to Christ for a new legal standing and a right relationship with God also produces the fruit of repentance and obedience. But while our practical righteousness remains incomplete in this life, our righteous status is complete the moment we are joined to Christ by faith. Hence, for Luther, the Christian life is a matter of the believer growing into what he already is; having been declared righteous in Christ, he now grows in practical and lived righteousness, so that when our salvation is finally finished in the resurrection, we have become in the end what God declared us to be in the beginning.
This understanding has substantial patristic precedent, even if sometimes obscured. For example, Augustine, though his doctrine of justification was not as sharply forensic as Luther’s, clearly distinguished forgiveness from inward renewal while holding the two inseparably together in the Christian life.
The challenge of Luther to the medieval church was both simple and profound: Can we, with Paul, say that justifies the ungodly? Can the believer know with certainly that his sins have been forgiven? Can the Christian be confident that he is a right relationship with God even as he continues to struggle and wage war against his remaining sins?
Conclusion
Luther’s doctrine of justification certainly broke with the dominant theology of the late medieval church. Yet it cannot fairly be reduced to philosophical nominalism. The Reformer’s deep suspicion of autonomous reason, his realist commitments to natural law, his view of the sexes, his theology of the sacraments, and—above all—his richly Christological account of justification rooted in union with the Savior, all point in a different direction. Luther was first and foremost a biblical theologian who let Scripture critique and reshape the categories he inherited. In the end, his teaching on justification magnifies the glory of Christ and the wonder of the gospel: the ungodly are not merely called righteous—they are righteous in the One who is their righteousness.
