Perhaps no philosophical position is more widely held yet more obviously flawed than relativism. In its various forms—moral relativism, cultural relativism, epistemological relativism—it pervades contemporary Western culture, shaping assumptions about ethics, religion, and truth itself. Yet relativism suffers from a fatal defect: it cannot sustain itself. The position is self-defeating, undermining its own claims the moment it makes them. Understanding this self-defeating character is essential for Christian apologetics in our relativistic age.
The Appeal of Relativism
Before critiquing relativism, we should understand why it appeals to so many people. The view is not arbitrary; it responds to genuine concerns and reflects certain cultural values.
Tolerance and Humility
In a diverse society, relativism seems to promote tolerance. If no moral or religious view is objectively correct, then we have no basis for imposing our views on others. Each culture, each individual, is free to construct their own values. This appears humble and respectful—who are we to say our views are better than anyone else's?
Awareness of Cultural Diversity
Exposure to different cultures has revealed that moral beliefs vary considerably across societies. What one culture considers virtuous, another condemns. This diversity suggests to many that morality is culturally constructed rather than objectively given. "When in Rome, do as the Romans do" becomes a philosophical principle.
Reaction Against Dogmatism
History is littered with examples of people claiming absolute truth and using that claim to justify oppression. Religious wars, colonialism, and ideological tyrannies have all been perpetrated in the name of "the truth." Relativism offers an escape from this dangerous certainty. If no one has the truth, no one can use truth to oppress.
Personal Autonomy
Relativism flatters our desire to be our own authorities. If truth is whatever I decide, then I am answerable to no one. I construct my own values, define my own identity, and live by my own rules. This radical autonomy appeals powerfully to modern Western individuals.
Insight
Understanding why people embrace relativism helps us engage them more effectively. Simply pointing out the logical flaws may not persuade someone whose relativism is motivated by genuine concerns about tolerance, humility, and human dignity. We must show that objective truth—particularly Christian truth—addresses these concerns better than relativism does.
Forms of Relativism
Relativism takes several forms, each with its own claims and vulnerabilities.
Moral Relativism
Moral relativism holds that moral judgments are not objectively true or false but are relative to individuals or cultures. "Stealing is wrong" is not a universal truth but is true only relative to particular moral frameworks. What is wrong for one culture may be right for another.
This can be further divided into cultural relativism (morality is determined by one's culture) and individual relativism (morality is determined by each individual). Both forms deny that moral truths hold across all cultures and individuals.
Epistemological Relativism
Epistemological relativism holds that knowledge itself is relative. There is no objective truth to discover, only different "truths" for different individuals, cultures, or communities. What counts as knowledge depends on one's conceptual scheme, language, or social location.
This is the more radical form of relativism because it relativizes not just values but all truth claims. Even scientific claims are seen as constructions of particular communities rather than discoveries about objective reality.
Religious Relativism
Religious relativism (sometimes called religious pluralism) holds that all religions are equally valid paths to the divine, or that religious truth claims are only true relative to particular religious communities. Christianity is "true for Christians," Islam is "true for Muslims," but neither is objectively more correct than the other.
This view is extremely common in contemporary culture. "All religions are basically the same" or "Many paths lead to God" express religious relativism in popular form.
The Self-Defeating Argument
The most powerful critique of relativism is that it cannot sustain its own claims. Each form of relativism, when examined carefully, undermines itself.
The General Problem
A position is self-defeating (or self-refuting) when its truth would establish its falsehood, or when the act of asserting it contradicts its content. For example, "I cannot speak a word of English" is self-defeating when spoken in English. "There are no truths" is self-defeating because it claims to be true.
Relativism faces precisely this problem. The relativist asserts that all truth (or all moral truth) is relative—but this very assertion claims to be objectively true. If it is only relatively true that truth is relative, then there might be objective truth after all. The relativist cannot state their position without exempting that very statement from relativism.
Moral Relativism's Self-Defeat
Consider the claim: "No moral judgment is objectively true; morality is relative to cultures or individuals."
Is this claim itself a moral judgment? If so, is it objectively true? If it is objectively true that morality is relative, then at least one moral claim (this one) is not relative, which contradicts the claim. If it is only relatively true, then there may be perspectives from which objective morality exists—and who is the relativist to say those perspectives are wrong?
Furthermore, moral relativists typically want to retain certain moral commitments—tolerance, for instance, or the wrongness of imposing values on others. But on relativist premises, these are not objectively obligatory either. Why should anyone be tolerant if morality is merely subjective? The relativist wants tolerance to be a real, binding obligation—but relativism cannot ground real, binding obligations.
Self-Defeating Statements
These statements illustrate the self-defeating pattern:
"There is no truth" — Is that true?
"You can't know anything for certain" — Are you certain of that?
"All statements are socially constructed" — Is that statement socially constructed?
"It's wrong to impose your morality on others" — Are you imposing that moral view on me?
"You shouldn't judge" — Isn't that a judgment?
Epistemological Relativism's Self-Defeat
The claim that all truth is relative (or that there is no objective truth) faces the same problem more starkly. "There is no objective truth" is presented as an objective truth. If it is merely a relative truth—true for some but not for others—then those who believe in objective truth are not wrong to do so. The relativist cannot both assert their view and allow that it might not apply to those who reject it.
Some try to escape by saying they are merely describing what they believe rather than making a truth claim. But this dodge fails. If relativism is merely a personal belief, why should anyone else accept it? And can the relativist really avoid making truth claims entirely? The very act of arguing for relativism involves claims the relativist considers true and wants others to accept.
Religious Relativism's Self-Defeat
Religious relativism—"all religions are equally valid"—also defeats itself. This claim about religions is itself a religious or metaphysical claim. It assumes a view of ultimate reality: that the divine is such that multiple, contradictory paths can all reach it. But this is not a neutral observation; it is a specific theological position—and one that most of the religions it supposedly affirms would reject.
Christianity claims Jesus is the only way to God (John 14:6). Islam claims submission to Allah through Muhammad's revelation is required. These are not compatible with "all paths are valid." The religious relativist, in claiming all religions are equally valid, actually contradicts the central claims of the religions they mean to affirm. They end up imposing their own metareligious view on all religions while claiming not to impose anything.
"Jesus said to him, 'I am the way, and the truth, and the life. No one comes to the Father except through me.'"
— John 14:6 (ESV)
Common Responses and Rebuttals
Relativists have offered various responses to the self-defeating objection. Each fails upon examination.
"That's Just Logic—I Reject Your Logic"
Some relativists, when confronted with logical contradictions in their view, respond by questioning logic itself. Perhaps the law of non-contradiction (nothing can be both true and false at the same time and in the same sense) is just a Western convention.
But this response is desperate. The person making it still uses logic—they form coherent sentences, draw inferences, and expect to be understood. They assume you will not interpret their words as meaning the opposite of what they intend. To reject logic is to reject meaningful communication itself. No one can consistently reject logic.
"I'm Just Describing How Things Seem to Me"
Some retreat to pure subjectivism: "I'm not making a truth claim; I'm just expressing my perspective." But this retreat empties relativism of significance. If the relativist is merely reporting their psychological state, they have nothing to say to anyone else. They cannot object when others disagree, cannot advocate for tolerance, cannot claim that objective truth is dangerous. The position becomes unfalsifiable by becoming vacuous.
"Relativism Is True Within Our Cultural Framework"
Some embrace the self-reference explicitly: relativism is itself a relative truth, valid within certain cultural frameworks. But this concedes the point. If relativism is only relatively true, then objective truth might exist in frameworks that reject relativism. The position has no critical edge; it cannot claim that non-relativists are wrong without abandoning its own relativism.
"You're Just Playing Word Games"
Some dismiss the self-defeating objection as mere word play or logical trickery, not engaging with the real substance of relativism. But the objection is not a trick; it identifies a genuine logical problem. If a position contradicts itself, it cannot be true. This is not pedantry but basic rationality.
Insight
When relativists dismiss the self-defeating objection, they often reveal that their commitment to relativism is more emotional or social than rational. They like what relativism allows them (autonomy, non-judgmentalism) and dislike what objective truth might require (accountability, submission to external standards). Recognizing these underlying motivations helps us engage not just arguments but hearts.
Practical Contradictions
Beyond the logical self-defeat, relativism fails the test of livability. No one can consistently practice what relativism preaches.
Moral Relativists Make Moral Judgments
Watch a moral relativist long enough, and you will see them make moral judgments. They condemn injustice, express outrage at cruelty, insist on their rights. They may say "it's all relative," but they live as if some things are really wrong—not just different from their preferences.
This is especially evident when the relativist is wronged. Steal their laptop, and they don't say, "Well, theft is only wrong in my cultural framework." They demand justice. Their moral sense overrides their philosophical theory.
Relativists Expect to Be Understood
When relativists argue for their position, they expect their words to convey meaning to others. They expect their audience to understand their claims, consider their arguments, and perhaps be persuaded. But this assumes a shared reality, shared concepts, shared logic—all of which epistemological relativism undermines. The relativist practices what their theory denies.
Religious Relativists Prefer Some Religions
People who claim "all religions are equally valid" rarely treat them equally. They typically prefer religions (or interpretations of religions) that emphasize tolerance, love, and inclusion, while criticizing those that make exclusive truth claims or have strict moral codes. But this preference is itself a religious judgment—a claim that tolerant religion is better than exclusive religion. The relativist is not really neutral among religions but advocates for a particular religious vision.
The Christian Alternative
Christianity offers a coherent alternative to relativism—one that addresses the legitimate concerns behind relativism without its fatal flaws.
Objective Truth Exists
Christianity affirms that truth exists objectively, grounded in the nature and character of God. God is truth (John 14:6); His word is truth (John 17:17); reality is what God has made it. This truth does not depend on human agreement or cultural construction. It simply is.
This grounds the moral intuitions that relativism cannot explain. Murder is wrong not because we decide it is but because God has created humans in His image. Justice matters not because it's useful but because God is just. These are objective facts about reality, as real as the law of gravity.
Human Access to Truth Is Limited but Real
Christianity acknowledges human limitations without sliding into skepticism. We are finite creatures who cannot know everything, and we are fallen creatures whose minds are affected by sin. Our knowledge is partial, perspectival, and fallible.
But God has revealed Himself in creation, in Scripture, and supremely in Christ. This revelation gives us genuine knowledge—not exhaustive or infallible apart from Scripture, but real. We can know truth because God has made it known. This is neither the arrogant certainty of some modernism nor the despairing skepticism of postmodernism but humble confidence grounded in revelation.
Truth Requires Humility, Not Arrogance
Relativists fear that belief in objective truth leads to arrogance and oppression. But the Christian understanding should produce the opposite. If truth is objective, we do not create it but receive it. We are not the measure of all things; God is. This should humble us—we are under truth, not above it.
Moreover, the central truths of Christianity are profoundly humbling: we are sinners who cannot save ourselves, dependent entirely on God's grace. This is not a foundation for arrogance but for gratitude and compassion toward fellow sinners.
"For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast."
— Ephesians 2:8-9 (ESV)
Truth and Love Go Together
Scripture calls us to "speak the truth in love" (Ephesians 4:15). Truth without love is harsh; love without truth is sentimental. The Christian vision holds them together. We tell the truth because we love people too much to leave them in comfortable falsehood. We speak lovingly because truth is meant to heal, not to harm.
This addresses the concern that truth claims lead to oppression. When truth is united with Christlike love, it liberates rather than oppresses. "You will know the truth, and the truth will set you free" (John 8:32).
Engaging Relativists
How do we engage people who hold relativist views? Several approaches can be effective.
Ask Clarifying Questions
Often, simply asking questions will reveal inconsistencies. "Do you think relativism is objectively true?" "Is it really wrong to impose values, or is that just your opinion?" "If morality is relative, is there anything that's genuinely evil?" Such questions, asked gently, can help people see the problems in their own position.
Point to Moral Intuitions
Bring up moral cases where relativist answers seem clearly inadequate. "Was the Holocaust really wrong, or just culturally unusual?" "If you discovered a culture that practiced child sacrifice, would you say they were doing something wrong?" Most people's moral intuitions resist the implications of their relativism. Help them see the conflict.
Affirm Legitimate Concerns
Acknowledge the concerns that motivate relativism—desire for tolerance, awareness of diversity, fear of dogmatism. Then show how Christianity addresses these concerns better. Christians should be the most humble people around, the most loving, the most genuinely tolerant (distinguishing tolerance from approval). If our commitment to truth makes us arrogant or harsh, we are not representing truth well.
Share the True Story
Ultimately, relativism offers no compelling story to live by—no meaning, no purpose, no hope. Christianity offers the true story of the world: creation by a good God, fall into sin, redemption through Christ, hope of restoration. This story satisfies our deepest longings in ways relativism's empty universe cannot. Invite people into the story, not just into an argument.
Conversation Starters
For moral relativism: "You say morality is relative. But I've noticed you have strong opinions about justice. What makes those opinions more than personal preferences?"
For religious relativism: "You say all religions are equally valid. But they make contradictory claims. Can contradictions both be true? And is your view itself a religious claim—a belief about the nature of ultimate reality?"
For epistemological relativism: "You say there's no objective truth. But you seem confident about that. How do you know it's true?"
Conclusion
Relativism, for all its cultural dominance, cannot sustain itself. It makes claims it cannot consistently make, advocates positions it cannot consistently hold, and lives by standards it cannot consistently justify. The emperor has no clothes—but many people are too polite (or too confused) to say so.
Christians need not be intimidated by relativism. We can expose its self-defeating character gently but clearly. We can show that objective truth—far from being arrogant or oppressive—is the foundation for genuine humility, justice, and love. And we can point people to the One who is Himself the truth, the way, and the life.
In a world drowning in relativism's confusion, the gospel shines as a beacon of clarity. There is truth. It can be known. And knowing it sets us free. This is good news for people exhausted by the burden of constructing their own meaning in a universe that offers none. We have something better to offer—not our truth, but the truth: Jesus Christ, in whom all the treasures of wisdom and knowledge are hidden (Colossians 2:3).
"But when he, the Spirit of truth, comes, he will guide you into all the truth."
— John 16:13
Discussion Questions
- Think of a recent conversation where someone expressed relativist views ("that's just your opinion," "who are you to judge?"). How might you have used the self-defeating argument to gently challenge their position? What questions could you have asked?
- The lesson notes that relativism appeals to people partly because of legitimate concerns: tolerance, humility, awareness of diversity, fear of dogmatism. How can Christians demonstrate that commitment to objective truth can coexist with—and even ground—genuine tolerance and humility?
- Relativists often cannot live consistently with their stated beliefs—they make moral judgments, expect to be understood, and prefer some views to others. Why do you think there is such a gap between professed relativism and lived reality? What does this suggest about what people actually believe?
