What God Has Joined Together

It helps me to remember that Jesus did not raise the subject of marriage out of nowhere. As Mark 10 opens, some Pharisees come to him and ask whether it is lawful for a man to divorce his wife, and Mark tells us plainly they were testing him (Mark 10:2). This was not an honest pastoral conversation. It was a trap, and a clever one, because divorce was a live argument among the teachers of the day and any answer would offend someone.

There is something in the setting too. Mark 10:1 places Jesus in Judea and beyond the Jordan, the area known as Perea, where John the Baptist had condemned Herod’s marriage and lost his head for it (Mark 6:18). So when Jesus answers, he is not theorising in a quiet study. He is a travelling teacher, on the road to Jerusalem and the cross, taking a public stand on the very subject that had recently cost a prophet his life. That gives his words a weight I think we miss if we only read the single verse on its own.

What strikes me most is where Jesus goes for his reply. The Pharisees ask about Moses, about what is lawful, about the certificate of divorce that Deuteronomy allowed. Jesus will not stay on that ground. He reaches back behind Moses, all the way to the beginning, and points to Genesis, to the man and woman becoming one flesh (Genesis 2:24). Then he adds his own line on top of it: “What therefore God has joined together, let no man separate.”

That small word “therefore” is doing real work. It is a hinge. Because God made them one at the start, because oneness was the design rather than a later add-on, the separating becomes something no person has the standing to do. Jesus treats divorce not first as a sin against a spouse but as a human hand reaching into something God himself put together. I find that sobering and oddly comforting at once. Sobering, because it lifts marriage above my preferences. Comforting, because my marriage was never held up by my own cleverness or stamina to begin with.

The Greek behind “joined together” here (syzeugnymi) carries the picture of being yoked, the same root that lies behind a pair of animals harnessed for one task. It is a strong, physical image, and it is worth sitting with rather than rushing past. A yoke is not a decoration. It is what lets two creatures pull the same load in the same direction without tearing each other apart.

There is a quiet detail in who does the joining, as well. The sentence is built so that God is the active one. He joins. The couple are the ones acted upon. That is easy to miss when a wedding feels so much like our own achievement and our own day. Years on, when the early glow has worn off and you are simply two tired people sharing a kitchen, this is the part I find holds. The bond was never my construction in the first place, so its survival is not mine alone to shoulder. The same God who tied it is still in the room.

That “one flesh” line from Genesis was always pointing somewhere larger than any single household. Paul takes the same verse and says it speaks of Christ and the church (Ephesians 5:31 to 32). So the love a husband is asked for is measured against the love that gave itself up entirely (Ephesians 5:25), and the staying power a marriage needs is the same patient love that Colossians 3:14 calls the bond holding everything together.

This is why I cannot read Mark 10:9 as merely a rule about exits. It sits inside a much bigger story, of a God who binds himself to a people who keep wandering off and who will not call the relationship over. Hosea was asked to live that out as a sign, marrying and staying faithful when faithfulness was costly. When Jesus protects the permanence of human marriage, he is also defending something about God’s own character. He keeps his covenants. Our small vows are a faint copy of his enormous, unbreakable one.

I want to be careful here, because this verse has been used as a club, and I have seen the bruises. It has been quoted at people trapped in real danger, or abandoned by a partner who left long ago, as though staying physically present were the whole of faithfulness. That is not what Jesus is doing. He is exposing a hard-heartedness that goes looking for the door. He is not condemning the person whose door was kicked in from the other side.

For most of us the application is quieter and far more daily. It is the resolve not to keep a private file of grievances, the willingness to say sorry first when every fibre of me wants to wait for the other one to crack, the small choice on a grey morning with nothing romantic about it to treat my wife as someone God himself joined to me rather than someone I am putting up with. When I forget that the joining is God’s work, I start grading her and finding her wanting. When I remember it, I have somewhere to take the strain that is not just my own thinning patience.

It is worth feeling how lightly some of his hearers held the whole thing. The question they bring assumes a man could end his marriage more or less when he chose, handing his wife a written certificate and sending her off, with little say on her side (Mark 10:4). Marriage there could be dissolved about as easily as it was entered, and a hard heart could always find grounds.

Jesus will not let it stay that small. He treats the bond as weightier than a contract you tear up when it stops suiting you. A contract is struck between two parties, and either of them can move to end it. He is describing something a third party made, and that changes who has any right to undo it. I notice how readily my own heart drifts to the contract view, keeping a private account of whether the arrangement still works for me.

If you are carrying a marriage that broke, or one that feels close to it now, I want to hand you the comfort inside this verse and not only its demand. Most of us picture marriage as two people trying, and trying, and slowly running out of road. Jesus puts a third person in the room from the very start. The God who joined you did not then step back to watch from the doorway.

That does not wave away the hard work, and it does not mean every marriage can be held together where there is real danger or desertion. But the weight was never resting on the two of you alone. When my patience is thin and I have nothing warm left to give, there is Someone else holding the bond who has not run out of love. You can ask him to carry the part you cannot.

For years I heard “let no man separate” as a general prohibition hanging in the air over marriage, aimed at nobody in particular and therefore at everybody. Put it back in the room and it lands much closer to home. The men in front of him had come asking about permission to leave (Mark 10:2). The hand reaching in to pull the two apart is the hand of the man holding the certificate. He is the “no man”. Jesus is not warning a husband about outsiders circling his marriage. He is telling him to look down at his own hands.

Which is why the commonest misuse of this verse runs in exactly the wrong direction. A divorced man’s name comes up for eldership, or for leading the youth work, and someone quotes Mark 10:9 across the table like a charge sheet. That inverts the thing. A word spoken to the one holding the pen gets turned into a licence for everyone else to hold the file, years after the marriage ended and long after any of them could have helped.

If you are building a talk from this passage, follow the room. Outside, on the road, with the Pharisees watching, Jesus gives the Genesis answer and the one line everybody quotes. Then the door shuts. Back in the house the disciples ask him about it again (Mark 10:10), and only there does he go further: whoever divorces and remarries commits adultery, and, remarkably, the same goes for a wife who divorces her husband (Mark 10:11 to 12).

That second half is the hinge for teaching this well. As I understand it, a wife under Jewish law could not issue the certificate herself, while a husband could, and Mark keeps her case in because his readers lived under Rome, where she could. I have not checked that against the legal sources with my own eyes, so hold it loosely rather than preach it hard. The shape stands either way. Indoors, with no crowd left to score points in front of, Jesus makes sure verse 9 cannot be heard as a rule aimed at somebody else’s sex. The public answer ends an argument. The private one shuts a loophole.

Long before it was a verse to argue over, this line was liturgy. The old prayer book puts it at the pronouncement, after the vows and the ring: those whom God hath joined together, let no man put asunder. And the minister says it to the room, not to the couple. I love that. It hands the congregation a job, and it says out loud that this marriage is now something all of us are on the hook to protect, not a private arrangement between the two people at the front.

Two places I would not take it. Not into the ceremony as a lecture delivered at the bride and groom, which turns the happiest morning of their lives into a small courtroom. And never to a widow at a graveside, however neatly the words seem to fit a marriage that has just ended. Jesus is answering a question about human choice, about a hand reaching in while both people are still living. Death is not that hand. Grief does not need this verse.

The part of this argument I resisted longest is not verse 9. It is verse 5. Jesus tells them Moses wrote that commandment for the hardness of their hearts (Mark 10:5), and it took me years to feel how startling that is. He is saying that a piece of the law of Moses stands there not because it maps God’s will but because it makes room for people who will not do God’s will. Scripture bending round our stubbornness. God permitting a rule he does not love, because the alternative was worse for somebody.

That should unsettle anyone who likes their Bible tidy, and I wanted mine tidier for a long time. It means you can quote a genuine commandment, accurately, chapter and verse, and still stand a long way from the heart of the God who gave it. That is exactly what the men in front of him had managed. Their proof text was real. Their reading of it was hard as flint.

And it cuts both ways, which is the bit that keeps me honest. If Moses could make room without approving, then permission and blessing are two different things, and a concession is not a licence to go looking for the door. But turn it over. The God in this scene already knew, long before that morning out beyond the Jordan, that hearts would go hard and homes would come apart, and he had put something in the law for that day anyway. He is not standing over the wreckage of a marriage looking startled. He never was.

Read on. Mark gives no scene break at all. The argument about certificates ends, and the very next thing in his account is people bringing children for Jesus to touch, with the disciples rebuking them for it (Mark 10:13). He is not mildly put out by that. Mark says he was indignant, and then he gathers the children up in his arms (Mark 10:16). I cannot prove Mark meant anything by the order of two paragraphs, and I will not build a doctrine on it. But I stopped being able to unsee them side by side.

Because nobody asks a child’s opinion before a door slams. Nobody hands a child a certificate. Everyone with the standing to argue the law that morning was an adult, and the people who would live longest with the answer were the ones being shooed away at the edge of the crowd.

Which is why, when a child asks me the plain question, and it is nearly always the child whose own parents split, this is the page I go to. I will not tell her that her family broke because somebody did not pray hard enough. I do not know that, and her parents’ hearts are not mine to guess at. I will not tell her marriage is unbreakable either, because she is standing in front of me as proof that in this life it sometimes breaks. So I tell her what happened after the argument finished. He never asked whose household they came from, or who was at fault, or whether their mum and dad were still together. He picked them up, and he said the kingdom belongs to people exactly like that.

Mark mentions the certificate almost in passing (Mark 10:4), and for years I read straight past it as a piece of legal furniture. Then I started asking the question Mark never answers. She walks out of the house holding a piece of paper. Where does she sleep that night?

I have to be careful, because I have not read the family law of that century with my own eyes and I will not pretend the fine print is settled in my head. But the broad shape is not seriously in doubt. A woman there had far less power to keep herself fed than a man did. No wage of her own, no flat of her own, no third option waiting. Her future ran through her father’s household taking her back, or another man agreeing to marry her, and if neither came off she fell, and she fell fast and a long way.

That is what I think goes missing when this turns into a tidy debate about grounds. The clever question put to Jesus is not two independent adults weighing a mutual decision. It is one person asking how much freedom he has to end another person’s entire means of living, on his own initiative, with a signature. So when Jesus digs his heels in, I do not hear an institution being protected. I hear a particular woman being protected, by the only person in that crowd who looked likely to bother.

Here is the part I have never got settled. Matthew’s version of this same teaching carries an exception Mark’s does not, for sexual immorality (Matthew 19:9). Mark hands you the flat statement with no exit named in it anywhere, and Luke is much the same (Luke 16:18). I have read the two accounts side by side for years and I still do not know what to do with the gap between them.

Think about who is reading. Picture someone whose husband was unfaithful for years, who finally left, who has been told by everyone who loves her that she did the only sane thing. She opens Mark and finds no exception clause at all. That is a door slamming a second time. She has already lived through the worst of it, and now the Gospel she came to for relief looks like it is withholding the one word she came for.

I am not going to manufacture a way round that. Honest Christians read Matthew’s clause as spelling out what Mark leaves implicit. Others hear two slightly different tellings of one saying, each shaped a little by the people it first reached. I hold both loosely rather than picking one and preaching it hard. The one thing I will not do is stand in front of her and say that Mark’s silence is God’s verdict on her life. I do not know that. I do not think anybody does.

Some twenty years on and several hundred miles west, Paul is writing to a church in Corinth full of awkward marriages, a few of them between a believer and someone who wanted nothing to do with any of it. He passes Jesus’s teaching on almost word for word, the wife not to leave, the husband not to send his wife away, and he takes care to say the instruction is the Lord’s and not his own (1 Corinthians 7:10 to 11). Then, a few lines later, he says something Jesus is never recorded saying. If the unbelieving partner insists on going, let them go. The brother or sister is not under bondage in such cases, because God has called us to peace (1 Corinthians 7:15).

I find that freeing rather than alarming. Paul plainly did not think he had been handed a legal code with all the thinking already done in it. He took the same conviction about the weight of the bond and carried it into a case nobody had ever put to Jesus: the one who did not do the leaving, left holding a marriage that only one of them is still inside. Mark guards a marriage against a hard heart hunting for the exit. Paul guards the person who was walked out on. I have never once managed without either of them.

• Where am I quietly keeping the exit in view, in my marriage or in some other commitment, instead of trusting the One who did the joining?
• If God is the active one who binds, what would change in how I treat my husband or wife this week, knowing the bond is not mine alone to hold up?
• Have I ever used a verse like this to judge someone who was actually being sinned against, and is there a hardness in me Jesus would want to expose?
• What is one grievance I could lay down today, and one apology I could offer first?

If you want to keep walking with this, you might read it alongside the rest of the book of Mark, or look through the verses gathered by how you feel for the days when your marriage is the thing that feels frayed.
