Cultural Relativism: Romans 1 Exposes the Suppressed Truth
Short answer: Cultural relativism claims that right and wrong are defined by a culture rather than by God, so no moral judgment can cross a cultural boundary. Romans 1:18-32 answers that claim directly: the problem in the human race is not missing information but suppressed information. Paul writes that the wrath of God is revealed against people who suppress the truth in unrighteousness, and he says what can be known about God is plain because God revealed it. Cultural relativism is not what happens when the evidence is inconclusive; it is one of the ways human beings manage the knowledge they already have and do not want. This does not make culture irrelevant. It makes culture a borrower: every society is a steward of moral knowledge it did not create.
What cultural relativism actually claims
Cultural relativism is not one thing. In anthropology it began as a methodological rule: do not judge a culture by the standards of your own before you understand it from inside. Applied cautiously, that rule is simply honesty. But the term has also become an ethical theory: right and wrong exist only within a culture, so no one may evaluate another culture's practices and no universal moral standard exists. That ethical version is the one in view here. It sounds humble, and it is often presented as the only humble option. But it is a positive moral claim defended with confidence, and it has to answer hard questions about those inside a culture who dissent.
The theory rests on a factual observation. Cultures really do differ over marriage, vengeance, hospitality, and the treatment of the dead. Romans 1 does not deny cultural variety. Paul writes to a congregation in the capital of a vast empire, a city saturated with foreign cults and the peculiar customs that came with them. He does not tell them every difference is meaningless. He tells them every human being, inside every culture, is dealing with the same God and the same suppressed knowledge of him. The variety is real. The relativist's inference from variety is not.
The disagreement is not between people who have information and people who do not. It is between two moral authorities. Either God defines good, and cultures approximate or distort it, or cultures define good, and God is a projection. Paul's argument in Romans is that the second option is a manufactured verdict, not a neutral conclusion. That is the central clash, and everything else in this article follows from it.
Romans 1 and the suppression of truth in unrighteousness
Paul begins with the wrath of God being revealed from heaven against ungodliness and unrighteousness. This wrath is a present reality, not merely a future event. The reason given is that people suppress the truth in unrighteousness. Three words matter here. Truth is something real that people possess, not something they are still looking for. Suppression is active resistance, like a hand pressing down on a lid. And the suppression is in unrighteousness, meaning the motive is moral, not intellectual.
Paul then explains why the suppression is so strange. He writes that which is known of God is revealed in them. He does not say a little is suspected. He says the knowledge is already there and already plain, because God himself made it plain. Creation itself is the testimony: invisible things, eternal power and divine nature, perceived in the things that are made. So the human problem is not a lack of evidence. It is the presence of evidence that a person has decided to hold down.
This is the point where cultural relativism collapses as an explanation. If knowledge is suppressed rather than merely absent, then relativism is either a symptom or a cover story. Paul says the cover story produces consequences. People become futile in their reasoning and their senseless hearts are darkened. That progression moves from suppressing truth to distorted thinking, not from distorted thinking to suppressing truth. The order matters: the culture follows the suppression; it does not generate the moral world from nothing.
Why every culture is a borrower, not an author
Scripture never treats any culture as the author of morality. Romans 1 implies the opposite: the moral order is a gift that cultures receive, often badly. Paul makes the point elsewhere in an extraordinary way, saying that Gentiles who do not have the law do by nature the things of the law, and that they are a law to themselves, showing the work of the law written on their hearts. The law is not a cultural invention any more than a language inventer invents the laws of logic by speaking.
This has serious implications for both sides of the debate. For the secular relativist, it means his own community's moral fervor is borrowed capital. Most western societies still demand human rights, protection for children, and care for the vulnerable. Those demands make sense only if a real moral order exists. For the religious person, it means no one has a right to equate his cultural customs with God's law. Paul rebukes law-keepers as sharply as law-breakers. He warns a Jew who rests in the law and boasts in God while dishonoring God that the name of God is blasphemed among the Gentiles because of him.
The Bible also speaks in counter-cultural terms, which only a realist about truth can do without contradiction. Acts records Paul in Athens telling a pagan city that God made from one blood every nation of men, having determined appointed seasons and the boundaries of their dwellings, so that they should seek him. The nations are not consigned to unknowable private moral worlds. They are given time and place so that they should seek him.
Distinguishing real cultural differences from moral ones
A wise Christian makes a careful distinction that relativists and reactionaries both blur. Many cultural differences are morally neutral. What you eat, what you wear, how you greet a stranger, whether you shake hands or bow: these are customs. Paul can say all things are lawful for me, but not all things are profitable. He says all things are lawful for me, but not all things build up. That is the language of a real freedom, and it assumes there are things indifferent enough to be free in.
But some differences are not morally neutral. Do they protect the weak or sacrifice them? Do they honor marriage as a covenant or treat spouses as property? Do they practice honest justice or bribe the judges? Romans 1 moves from idolatry to the specific kinds of disorder that follow. Paul does not say a particular culture invented these; he says that when people exchange the truth about God for a lie, God gives them over, and the results are visible in the body, in the family, in the neighborhood. The consequences are not arbitrary. They are moral consequences of a moral exchange.
So the Christian does not say, all differences are wrong. He says, some differences are just weather; some differences are wounds. Learning which is which requires both Scripture and patient, humble knowledge of real people. A blanket relativism can be as lazy as a blanket condemnation. The Bible calls for discernment, not reflexes.
Where the relativist's ethic stops working
There is a well-known argument against ethical relativism. If morality is whatever a culture approves, then a majority that approves enslaving a minority is morally correct, and a reformer who opposes it is morally wrong. Yet almost no one, including the relativist, believes this when the slavery is in his own country's past. We do not say the practice was right for its time. We say it was wrong. That judgment smuggles in a standard above culture, which is exactly the standard relativism denies. The theory cannot survive its own best moral moments.
The same happens with women, children, and minorities. Much of the modern moral passion for the vulnerable is inherited from the biblical tradition. Genesis says every person bears God's image. That is a universal claim, and it is why Christians have often led in abolition, orphan care, and the protection of the unborn. You cannot ground universal human dignity on cultural agreement, because cultural agreement has not been universal. You can only ground it on a God who is not the property of any culture.
Paul says something similar in a pointed way when he says the Gentiles who do not have the law are a law to themselves. If that is true, then the relativist's own sense of justice is a witness against his own theory. He cannot stop believing in right and wrong long enough to live consistently as a relativist. That is not an insult. It is Paul's diagnosis, and it applies to all of us.
Truth, freedom, and the escape from suspended judgement
Cultural relativism is often sold as freedom, the freedom not to be judged. It delivers something else: permanent suspension. If no standard exists, no one can be wrong, and no one can be vindicated either. An abused wife has no standing to call her treatment evil; she can only report what her culture prefers. To its credit, our culture does not actually live that way. It still speaks as though some things are evil everywhere. To its cost, it has forfeited the framework that makes those judgments more than tribal preference.
Jesus makes a claim that relativism cannot accommodate. He says, I am the way, the truth, and the life. No one comes to the Father, except through me. That is not one option among many; it is the way itself. To people who had believed in him, he also said, You will know the truth, and the truth will make you free. Truth in Scripture is not a cage. It is the ground of freedom, because it names what is real and what is broken, and it points to the one who can mend it.
The Christian therefore approaches other cultures differently than either relativism or contempt. He refuses to call evil good, in his own culture or another. He refuses to call his own customs divine. He looks for the image of God, the conscience, the longing that every culture shows. And he tells the story from Paul's speech in Athens: God has overlooked the times of ignorance, but now commands all people everywhere to repent, because he has appointed a day on which he will judge the world in righteousness. That message is not relativist. It is also not proud. It is the message of people who have been saved from their own suppression of the truth.
Biblical fidelity check
What Romans 1:18-32 establishes is this: a knowledge of God is universally available and universally suppressed, the suppression is moral rather than intellectual, the consequences are a darkened mind and disordered life, and God gives people over to the things they have chosen. The passage also establishes that God's judgment is just, because what is known plainly is not hidden from those who reject it. What the passage does not establish is any particular list of cultural practices you should condemn first, nor does it authorize one nation to pronounce on every custom of another. Paul's argument is theological before it is cultural.
A common misreading says the passage is only about ancient paganism, so it no longer speaks to modern life. That is wrong on two counts. First, the mechanism described is not limited to one era; it is how a person, any person, handles unwanted knowledge of God. Second, Paul is writing to a church, not to outsiders only. He warns people who know the truth not to suppress it. The passage also does not teach that every cultural influence is demonic. Careful readers distinguish between the created good that cultures preserve and the distortions that cultures tolerate. That distinction is not in the text as a rule, but it flows from creation and conscience together.
Other passages that speak to Romans 1:18-32
Paul's argument continues into the next chapters, and the themes here connect with the rest of his letters. If you want to trace how a church applies the call to be of one mind in the face of competing loyalties, see What Does 1 Corinthians 1:10 Mean? Context, Theology, and Application. The calling that grounds that unity, God's faithfulness that makes it possible, is treated in What Does 1 Corinthians 1:9 Mean? Context, Theology, and Application. For the opening movement of that letter as a whole, including the themes of calling and boasting, see 1 Corinthians 1: Called, United, and Boasting in the Lord. And for the practical outworking of freedom, conscience, and the good of others, the warnings and freedoms of a later chapter are gathered in 1 Corinthians 10: Warnings and Freedom.
Frequently asked questions
Does Romans 1 mean all cultures are equally wrong?
It means all people within all cultures share the same fundamental problem. Paul does not single out one civilization for special condemnation; he describes the race. But cultures are not equally wrong in every respect. Some traditions protect the unborn, honor the elderly, or demand honesty in court, and those are real goods, borrowed from the moral order God built into creation. Others tolerate practices that dehumanize the weak. The text gives us the framework, not a scorecard. Applying it honestly requires care and humility in every setting, including our own.
If everyone suppresses the truth, how can anyone be saved?
Romans 1 is diagnosis, not final verdict. Paul goes on in the letter to say that the righteousness of God has been revealed apart from the law, through faith in Jesus Christ for all who believe. The gospel is precisely the remedy for suppression. It does not say people earn their way back by better guessing; it says God acts. This is why missions and preaching matter. Paul says faith comes by hearing, and hearing by the word of God. The church is the community that speaks the suppressed truth back out loud, with grace and clarity, to people who are already missing it.
Can a Christian respect other cultures without being a relativist?
Yes, and Scripture requires it. Paul in Athens studied the city's objects of worship and quoted its poets in order to speak to its people. He did not sneer. He told the truth about creation, providence, and judgment, and he did it in their own idiom. Respecting a culture means learning it well enough to love the people inside it, not flattering its errors. It also means refusing to confuse our own customs with God's commands. The Christian is free to eat, dress, and speak as an outsider, and free to honor God's law above every culture, including his own.
