It’s one of the most searched, most personal questions facing the church today. Across the United Kingdom, North America, Australia and far beyond, the law of the land now recognises same-sex marriage. And a growing list of denominations have decided to bless and perform these unions. The pressure on ordinary congregations is therefore real, and it’s rising.
The historic Christian answer is no—not because the church is being stubborn or unkind, but because the church doesn’t believe marriage is hers to redefine. This article explains why. Let’s walk through what the Bible says, what the church’s confessions have taught for centuries, where the law stands country by country, and what a faithful church leader can do when the pressure arrives.
First, What Are We Actually Asking?
It helps to separate two things that often get tangled together. There’s civil marriage, the legal status granted by the state, and there’s what we might call covenantal marriage—marriage understood as a sacred, lifelong bond established by God. When a minister conducts a wedding, two things usually happen at once: the couple enters a legal contract recognised by the government, and the church declares God’s blessing on a union it believes God Himself has joined.
The second part is the heart of the matter. A church conducting a wedding isn’t merely witnessing paperwork; it’s standing before God and the congregation and saying, in effect, “This is marriage, and God blesses it.”
So the real question isn’t whether two people can love one another or build a life together—of course they can—but whether the church can place God’s name on a same-sex union and call it a marriage. That’s a theological question before it’s ever a legal or emotional one.
What the Bible Says About Marriage
Christianity’s understanding of marriage doesn’t begin with a list of prohibitions. It begins on the opening pages of the Bible, with what theologians call a creation ordinance—a pattern God wove into the world from the very start, before sin entered, for the good of all people everywhere. In Genesis, God makes humanity male and female and then declares, Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh (Genesis 2:24). Marriage, on this account, is the union of a man and a woman, and the complementarity of the two sexes is written into its very definition.
This is no obscure proof-text. When Jesus Himself was questioned about marriage and divorce, He reached straight back to these verses: Have you not read that he who created them from the beginning made them male and female (Matthew 19:4), before quoting Genesis on the one-flesh union. Jesus grounded marriage in creation, in the deliberate pairing of male and female. He treated the Genesis pattern as the permanent design, not a passing cultural custom open to later revision.
The deepest reason, though, surfaces in the New Testament. The apostle Paul tells us marriage is a living picture—a type, the theological word for an earthly thing that points to a greater spiritual reality. Writing of husband and wife becoming one flesh, he says, This mystery is profound, and I am saying that it refers to Christ and the church (Ephesians 5:32). Marriage was designed to enact the gospel itself: the self-giving love of Christ the bridegroom for his bride, the church. The two parties who’re different yet united—husband and wife, Christ and church—are essential to the picture. This is why the male-female structure of marriage isn’t an arbitrary rule the church may quietly drop. To redefine marriage is to paint over a picture God painted to display the gospel.
Alongside this positive vision, the Bible also speaks plainly about same-sex sexual activity in several places (Romans 1:26-27; 1 Corinthians 6:9-11; 1 Timothy 1:10). These passages are sometimes disputed, and we shall return to the disputes below. But notice the central Christian case doesn’t stand on them alone. It rests on the positive, creation-rooted, gospel-displaying definition of marriage that runs from the first chapters of Scripture to the last, where the whole story closes at the marriage supper of the Lamb (Revelation 19:9). You cannot lift a same-sex union into that picture without changing the picture.
What the Historic Confessions Say
Christians have never had to work all this out from scratch in every generation. Down the centuries the churches produced confessions. On marriage, these confessions speak with one voice.
The Westminster Confession of Faith, drawn up in the 1640s and still the doctrinal standard of many churches around the world, opens its chapter on marriage with a sentence that settles the question on its own: “Marriage is to be between one man and one woman” (Westminster Confession of Faith 24.1). It could hardly be plainer. The same chapter presents marriage as God’s institution for the good of husband and wife, the raising of children, and the guarding of purity.
The Heidelberg Catechism, written in 1563 and treasured across the European churches, approaches the subject through the seventh commandment, “You shall not commit adultery.” It teaches that God forbids “all unchastity” and that, because our bodies are temples of the Holy Spirit, He wills us to keep them pure and self-controlled (Heidelberg Catechism, Lord’s Day 41). The older catechisms saw no need to name every possible variation; they understood the commandment to fence sexual intimacy within the marriage of a man and a woman, and to call everything outside that fence sin.
There’s a further point the confessions press, and it bears directly on our question. The Belgic Confession, listing the marks of a true church, says a church “governs itself according to the pure Word of God” and exercises discipline to correct sin rather than excuse it (Belgic Confession, Article 29). A church doesn’t get to keep the title “faithful” while quietly setting aside what God has said.
On marriage the confessional inheritance is united and unambiguous: marriage is the covenant union of one man and one woman, and the church’s task is to uphold that definition, not to revise it.
What Mainline Denominations Do, and Why They’re Wrong
If the Bible and the confessions are this clear, why do some churches now perform same-sex weddings? The churches that have changed are mostly what are called the mainline denominations—the older, historically large Protestant bodies, as distinct from evangelical or confessional churches. The list has grown long. In the United States, the Episcopal Church (2015), the Presbyterian Church (USA) (2015), the United Church of Christ and the Evangelical Lutheran Church in America all permit clergy to marry same-sex couples. In 2024 the United Methodist Church, one of the largest Protestant denominations on earth, removed its bans on same-sex weddings and on ordaining partnered gay clergy, leaving the decision to each minister and congregation. In Britain, the Scottish Episcopal Church (2017), the Church of Scotland (which approved clergy conducting same-sex marriages in 2022) and the United Reformed Church (2016) now allow them. In Canada, the United Church of Canada leaves the choice to each congregation.
How do they justify it from the Bible? The arguments vary, but they tend to share a method—a way of reading the text that scholars call a hermeneutic. Some claim the biblical writers only condemned exploitative or idolatrous same-sex acts, not the loving, committed partnerships supposedly unknown in the ancient world. Others argue the prohibitions reflect the limited cultural horizon of their day, and that the Bible’s deeper “trajectory” towards love and inclusion should now carry us past the specific texts. Still others simply give the surrounding culture’s understanding of love and identity the final word, and read Scripture in its light.
These readings don’t hold, for two reasons.
- First, they cannot survive close contact with the texts themselves. The New Testament scholar Robert Gagnon has shown at length that the biblical prohibitions are sweeping and unqualified rather than narrowly aimed at abuse; Paul’s argument in Romans appeals to creation and to nature, not to one particular Roman vice. Kevin DeYoung makes the same case more briefly: the Bible’s “no” to same-sex practice is consistent across both Testaments and is tied directly to its “yes” to male-female marriage.
- Second, and more decisively, the revisionist case must do something the church has no authority to do—it must redefine marriage at its root. Even if every disputed verse were set aside, Genesis, Jesus and Ephesians would still define marriage as the one-flesh union of man and woman that pictures Christ and the church. The mainline churches haven’t discovered a new reading of a few hard verses; they’ve quietly accepted a different definition of marriage altogether. That’s why faithful churches regard the change not as a development of Christian teaching but as a departure from it.
It’s worth adding these decisions have rarely brought peace. Several denominations have fractured over the issue, with traditional congregations departing to form new bodies. None of this settles the question on its own, but it does suggest that abandoning the historic definition tends to divide churches rather than unite them.
The Legal Situation Around the World
A great deal of confusion comes from blurring the law of the land with the duty of the church. In most of the Western world, same-sex marriage is now legal as a civil matter: in Canada since 2005, across the United States since the Supreme Court’s Obergefell decision in 2015, in England, Wales and Scotland since 2014 (and in Northern Ireland since 2020), and in Australia since December 2017. Wherever you’re reading this, the state very likely recognises same-sex marriage.
But here’s the crucial point for any worried church leader: civil legality has never meant churches are required to perform these weddings. The law has generally gone out of its way to protect them. When England and Wales legalised same-sex marriage, Parliament built in what was nicknamed the “quadruple lock”, which expressly prevents religious bodies from being compelled to conduct same-sex marriages and makes it unlawful for the established Church of England to do so without further legislation of its own. Australia’s 2017 Act protects ministers of religion who decline. In the United States, the First Amendment’s guarantee of religious freedom shields churches and clergy. Even denominations that now allow these weddings state explicitly no minister can be forced to perform one. In short, the state may have redefined civil marriage, but it has handed the church no mandate. The pressure a leader feels is almost always social, relational or denominational—rarely legal.
A Word to Pastors Who’re Being Pressured
For ministers or elders feeling the weight of this, a few things are worth holding on to.
- We’re not being asked to be cruel; we’re being asked to be faithful. Declining to conduct a same-sex wedding isn’t a failure of love. It’s a refusal to tell a couple that God blesses what He hasn’t blessed, which would be the deeper unkindness. The most loving thing a shepherd can do is tell the truth, gently. And without flinching.
- Distinguish the person from the request. We can hold the line on marriage while treating every individual who walks in through our door with warmth, dignity and real pastoral care. People are made in the image of God; they’re never the enemy. Sam Allberry, who writes as a Christian committed to celibacy on account of his own same-sex attraction, puts it memorably: the church’s calling is to offer people not less than the world offers but more—real belonging, real family, real hope—within God’s design rather than around it.
- Help the church decide before the moment comes. Pressure is hardest to resist in the heat of a particular pastoral situation. Far better for a congregation to settle its position in calm times, ideally written into a clear marriage policy and statement of faith, so that no individual minister is left exposed and no decision is forced under emotional duress. If your denomination is drifting, seek out the fellow churches, networks and accountable structures that will stand with you.
- Expect a cost, and count it worth paying. Holding the historic view may bring disapproval, strained relationships, even legal complexity over the use of buildings. Jesus never promised otherwise. But a clear conscience before God, and faithfulness to a couple in the deepest sense, are worth far more than the approval of the age.
The Heart Behind the Answer
Behind every search for answers to this question are real people, and the Christian message to them is not “stay away” but “come and find life”. The very passage in 1 Corinthians that names sexual sin goes on to say something staggering to the church at Corinth: And such were some of you. But you were washed, you were sanctified, you were justified (1 Corinthians 6:11). The gospel has always assumed churches are full of people being remade.
Rosaria Butterfield, once a lesbian professor of literature and a vocal critic of Christianity, came to faith in Christ through the patient hospitality of a pastor and his wife who never diluted what they believed, yet loved her relentlessly while she worked it through. Her story is a standing reminder that holding to the truth and loving people aren’t rivals; they belong together.
So no, the church cannot conduct same-sex weddings. That’s because marriage isn’t hers to redefine. And the gospel it pictures isn’t hers to revise. Yet the same church can—and must—be the warmest, most welcoming place on earth for anyone wrestling with these questions. The answer to the question is no. The posture behind the answer is open arms.
Tough Questions, Honest Answers
Isn’t refusing to conduct a same-sex wedding simply discrimination?
It depends what you mean. The church applies one standard to everyone: it conducts only those weddings that fit what it believes marriage is—the lifelong union of a man and a woman. It would equally decline to marry an opposite-sex couple where the union broke the same definition—for example, marrying someone to a second spouse while they were still married to a first. The refusal isn’t aimed at a category of people; it follows from a definition that applies across the board. Declining to redefine marriage is different from rejecting persons.
What’s the difference between blessing a couple and marrying them?
This distinction has become important, especially in the Church of England, which now permits prayers of blessing for same-sex couples in regular services but doesn’t marry them, and hasn’t changed its definition of marriage. Supporters present blessing as a pastoral middle way. Many who hold the historic view, however, see little real difference: to ask God to bless a union is already to imply that He approves of it, which is the very thing in question. On the older confessional understanding, the church shouldn’t pronounce God’s blessing on what His Word does not bless.
Can a church be forced by law to perform a same-sex wedding?
In the major English-speaking countries, no. Same-sex marriage is legal as a civil matter, but the law has consistently shielded religious bodies and ministers from being compelled, through the “quadruple lock” in England and Wales, religious exemptions in Australia, and First Amendment protections in the United States. The pressure on churches is real, but it is overwhelmingly social and denominational rather than legal. If you ever face a specific legal threat, take proper local legal advice, because the details differ from country to country.
Aren’t the Bible’s passages about same-sex relationships really about something else, such as exploitation or idolatry?
This is the most common revisionist argument, and it doesn’t survive a careful reading. As Robert Gagnon and others have demonstrated, Paul’s language in Romans 1 is broad and rooted in the male-female design of creation, not narrowly targeted at abusive or pagan practices. More decisively, the Christian case does not rest on these texts alone. Set every disputed verse aside, and the positive definition of marriage in Genesis, on the lips of Jesus, and in Ephesians still remains—and that is what a same-sex wedding cannot fit.
What should I do if my own denomination starts allowing same-sex weddings?
First, remember a denominational vote doesn’t bind your conscience to act against Scripture; most such decisions explicitly protect ministers who decline. Settle your own church’s position clearly and in writing before you are pressed. Seek out faithful networks, fellow ministers and accountable oversight who share your convictions. And weigh prayerfully, with wise counsel, what degree of association you can maintain in good conscience. Many have found they could remain and bear witness; others have concluded they had to leave. Both paths call for humility. And loads of courage.
Can someone with same-sex attraction be a member of, or serve in, the church?
Yes. The historic view distinguishes between temptation and sin, and between a person and a practice. A believer who experiences same-sex attraction yet seeks to follow Christ in obedience is a brother or sister like any other, and many such Christians serve faithfully and fruitfully. Writers such as Sam Allberry and Rosaria Butterfield have shown how rich a life of discipleship this can be. The call to chastity outside the marriage of a man and a woman falls on everyone alike, married and single.
If we say no to conducting same-sex weddings, aren’t we singling out gay people while ignoring other sins?
That’s a fair challenge, and churches should take it to heart. A congregation that thunders about same-sex marriage while shrugging at heterosexual cohabitation, casual divorce, pornography or greed is being inconsistent, and the inconsistency is itself something to repent of. The biblical sexual ethic is a single standard that falls on all of us. Holding it with integrity means applying it evenly, beginning with ourselves, and always pointing to the same grace that every sinner needs.
