“Let Not Man Separate” Implies a Breakable Bond (JDR-7)

This post continues my series on Jesus, divorce, and remarriage, where I examine Jesus’ words with a focus on this question: Did Jesus believe that marriage is indissoluble? Here are my posts so far:

Summary of this post: I ask whether Jesus meant “let not man separate” or “let not man try to separate,” as some propose. Based on clues from literary and historical contexts, I argue that Jesus’ first listeners understood him to be prohibiting the full dissolution of marriage—and that Jesus expected to be understood this way. I note that some proponents of marriage indissolubility acknowledge such a conclusion is reasonable, yet point ahead to Jesus’ statement about remarriage being “adultery” as proof that marriage is indissoluble. I promise to address this statement and acknowledge some complexities of this divorce discussion. 


Before I jump into today’s post, I feel I should clarify some potential misunderstandings about my goals in this series:

  • If you are confused about my purposes or beliefs, please read my post promoting radical faithfulness in marriage.
  • I’m trying to choose my post titles carefully. When I say a certain expression “does not imply an unbreakable bond,” I do not necessarily mean “implies a breakable bond.” Similarly, when I say “implies a breakable bond” in today’s post, I definitely do not mean “proves a breakable bond.” That said, after a while, enough non-implications plus implications do add up to a beyond-all-reasonable-doubt sort of proof. I’m definitely not there yet, though, in this series, so thank you for not saying I’ve claimed something I’ve not yet claimed!
  • I’m somewhat conflicted about naming and quoting people that I’m disagreeing with, especially when I know them personally. I’ve been on the receiving end of enough critique to know that public critique—even when it is respectful and perhaps especially from friends—can be uncomfortable and even potentially debilitating. I’m also aware it is easy to be misunderstood and that none of us still agrees with everything we’ve ever said or taught in public. That said, (a) it is standard, respectful academic procedure to sharpen thinking by quoting and evaluating the public teachings of others, (b) such public discussion of the public teachings of others seems consistent with the NT’s picture of the greater accountability expected of church leaders, and (c) for the purposes of my series it seems that direct quotations will help some readers better understand the significance, within the conservative Anabaptist context, of the questions I am discussing.
    Please know I have a lot of respect for many of the people I’m quoting and disagreeing with in this series! Many of them, to paraphrase Jesus’ parable (Matt. 13:23), are bearing gospel fruit thirtyfold and sixtyfold, compared to my own tenfold (on a good day).
    If I quote you in this series and you think I’m misunderstanding you or quoting something you no longer affirm, please let me know. I will be happy to do my best to correct any misrepresentations. I hope we can learn from each other, and I sincerely wish you God-speed in your kingdom work and worship.

Thank you for reading these clarifications. And now… on to today’s post!


Introduction: Should Not or Cannot Separate?

“Let not man separate” is the command that Jesus gives after summarizing the union that God designed for husbands and wives (Matt. 19:6). Since it is God who has joined a husband and a wife, separating marriages is a sin against God, not merely against humans.

This clause “let not man separate” offers a classic illustration of how Bible readers can get confused between the “should” and “could” of Scripture. The most obvious way to Jesus’ command is that he is saying humans should not do something that they could do. As commentator R. T. France noted, “the argument here is expressed not in terms of what cannot happen, but of what must not happen: the verb is an imperative: “let not man separate.”[1]

Bible teachers who believe marriage is indissoluble are often discontent with that simple reading, however.

John Piper, for example, waffled in his comments on this verse. First, he gave this summary: “Jesus… says that none of us should try to undo the ‘one-flesh’ relationship which God has united.” But later, citing this same statement of Jesus, Piper said “only God, not man, can end this one-flesh relationship.”[2] So which is true? Man should not separate, or man cannot separate?

To be fair, Piper’s two statements are indeed consistent with each other—but only because Piper added “try to” to Jesus’ prohibition on separating husbands and wives. Is this fair? Did Jesus mean “let not man separate,” as his words are recorded? Or did he actually mean “let not man vainly try to separate” or perhaps “imagine they have separated”?

How Did Jesus Expect to be Understood?

How would Jesus’ hearers have understood him? I see at least four reasons why Jesus’ hearers would have understood him to be implying that a marriage can, indeed, be dissolved.

First, nothing Jesus has said so far suggests that marriage is indissoluble. Remember, when Jesus says we are not to separate “what God has joined,” he is pointing back to what he just said—that God made humans “male and female” and therefore a man shall “hold fast” to his wife and they shall become “one flesh.” As noted in previous posts, none of this language implies that marriage involves an unbreakable bond. To the contrary, all this language was used elsewhere to refer to bonds that can be broken. This suggests that there is a real possibility that “what God has joined” could be “separated.”

Second, the words joined and separated are virtual opposites, and the way Jesus paired them reinforces the idea that they should be understood that way. For example, I could say, “I’m sleeping, so stop talking,” and we could debate whether talking has the potential to undo my sleeping or whether talking has some other possible effect that concerns me. But if I say, “I’m sleeping, so don’t wake me up,” then it is clear: waking me up will end my sleeping! (Let’s not get distracted about why I’m talking in my sleep.) Similarly, Jesus’ direct pairing of the opposite terms joined and separated puts the burden of proof on anyone who argues that the latter does not undo the former.

Third, in no other case, to my knowledge, does Jesus forbid humans from doing something that is actually impossible to do. I’ve actually looked, and I can’t find such an example. The closest, perhaps, might be this: “When you give to the needy, do not let your left hand know what your right hand is doing” (Matt. 6:3). On a literal level, true, it is impossible for your left hand to know what your right hand is doing! But that statement uses obvious hyperbole and is thus very different from Jesus’ straightforward command against separating what God has joined. On a practical level, there is nothing hyperbolic whatsoever about the possibility of separating a husband and a wife. It is a possible, common event.

Fourth, Jesus was engaging Jews on a question about divorce, and virtually everyone at the time—Jews and Greco-Romans alike—understood that divorce completely dissolved a marriage, freeing one for remarriage. “Is it lawful to divorce one’s wife for any cause?” was the question. “What God has joined together, let not man separate” was Jesus’ answer. Significantly, Jesus’ term “separate” (χωρίζω) was frequently used in both informal and legal contexts at the time to refer to divorce. True, it can have a more general meaning, and it probably does carry broader implications here. But Jesus’ hearers would certainly have heard it as referring most directly to divorce—thus, in their understanding, obviously referring to the full dissolution of a marriage.

Judging by these four reasons, Jesus’ command to not separate strongly implies that marriage is not an unbreakable bond. His listeners heard him clearly imply that marriage can indeed be dissolved by humans. What is more, Jesus, as a fellow Jew and a master teacher, knew that his listeners would understand him this way. In short, Jesus was using ordinary words in ordinary ways to forbid an ordinary occurrence: the full breakup, destruction, and dissolution of a marriage.

Cornes’ Concession

That much is relatively clear. And it is important to pause here and emphasize that, up until this point in Matthew 19 (verse 6), all Jesus’ words are consistent with one conclusion: Marriage can, indeed, be dissolved by humans.

On this point Andrew Cornes is admirably clear and honest. Even though he ultimately argues for “the impossibility of true divorce or remarriage,” at this stage in his analysis of Jesus’ conversation with the Pharisees, Cornes pauses to make the following statement:

Jesus has not (yet) said that husband and wife cannot be separated, that this is an impossibility. He has only said that they must not be separated. He has spoken only of the moral obligation not to divorce and stated that it would be a sin against God to divorce one’s partner or to cause the break-up of a marriage. In the next verses, however, he goes considerably further.[3]

(In fact, Cornes wrote this comment right after his discussion of Mark 10:9. Since Mark’s account varies slightly from Matthew’s, Corne’s comment covers not only all Jesus’ statements we’ve discussed so far but also his comments about Moses, which Matthew includes in verses 7 to 8.)

Was Jesus Prohibiting Only the External Separation of Marriage?

Those who don’t think Jesus meant humans can truly separate what God has joined, then, come to that conclusion either based on alternate readings of terms like one flesh or because of what Jesus says later in the passage. For example, here is the assessment offered in Divorce and Remarriage: A Permanence View, a multi-author book that some conservative Anabaptists recommend:

Jesus’ prohibition of divorce in Matthew 19:6 and Mark 10:9 is sometimes thought to refute the above point [that a marriage “union is permanent until death”]. Since He commands us not to separate what God has joined together, it is reasoned that it is possible to separate what God has joined together. After all, why would He prohibit us from doing something that is impossible? But by looking at the matter in its fuller biblical context (as is the intent of this book), we will see that Jesus must have been prohibiting the external separation of marriage. The vows spoken at a wedding can certainly be disregarded, and a marriage certainly can be separated in civil and legal ways, but these external disruptions of marriage do not and cannot destroy the morally binding one-flesh union created by God. Otherwise, no reason would exist for Jesus to call remarriage after divorce “adultery.”[4]

This paragraph is so full that I can’t offer a comprehensive response here. The authors wrote a book to try to prove their argument and it could take a book to respond. That said, I want to make several quick observations.

First, yes, it is theoretically possible that Jesus could have meant don’t legally or physically separate a union that it is impossible to truly separate. It is possible, and it can appear almost certain, if you bring particular assumptions to the text. The four reasons I presented above, however, strongly indicate that Jesus knew his first listeners would not understand him this way. I see no reason to abandon the most natural reading unless forced to do so.

Second, notice how these authors, right at the climax of their argument, described marriage as “the morally binding one-flesh union created by God.” This pile-on of emotion-laden terms is a non-argument obviously intended to help convince the reader. I say “non-argument” because “morally binding” merely shows one should not separate a marriage, not that one cannot. And the only term in that clause that could perhaps indicate that marriage is indissoluble—“one-flesh”—actually does not, as we have seen.

Third, and most important, the one actual argument the authors offered is based on what Jesus will say later in this account, when he calls remarriage after divorce “adultery.” If it is possible to separate a one-flesh union created by God, then how could Jesus call a post-divorce marriage “adultery”? This is a good question. In response, I’ll plant two small seeds now, with plans to develop them in future posts:

(1) Yes, Jesus calls remarriage after (some) divorce “adultery,” but what is the biblical picture of what adultery does to a marriage?

(2) What about the exception Jesus gave to the statement that remarriage is adultery? Would not even one exception show that marriage is not truly indissoluble?[5]

For reasons such as these, I find the arguments that Jesus was merely prohibiting the external separation of marriage unconvincing. Certainly he did forbid that, but I believe he was prohibiting complete separation, too.[6]

As Mrs. Reagan learned in her campaign against drug use, something remains possible to do even after you’ve been told to “just say no” to it. (Yes, I know the comparison with Jesus’ divorce command is imprecise.) Ronald Reagan Presidential Library, Public domain, via Wikimedia Commons

Complexities and a Conclusion: “Let Not Man Separate” Implies Marriage is Dissoluble

Before I finish this post, I want to observe that there is inevitable complexity about talking about marriages that have been ended. For example, when Jesus says one who “marries” another “commits adultery,” he affirms that a remarriage is indeed a marriage even as he condemns it (Matt. 19:9, etc.). Similarly, Paul says a divorced Christian wife “should remain unmarried or else be reconciled” to her Christian husband (1 Cor. 7:11). His words show that it is possible in one breath to talk about marriage having ended (“unmarried”) but about obligations still remaining.[7]

Both examples underscore again the necessity of distinguishing between the “could” and “should” of Scripture. It must also be noted that neither Jesus nor Paul apply the above statements to all divorce and remarriage situations; Jesus did not say all divorces and remarriages are adultery, nor did Paul say obligations remain after every kind of divorce.

Given these complexities, I acknowledge I puzzled long and hard over how to express myself in this post. I encourage both “sides” (those arguing for marriage indissolubility and those arguing against) to be kind to each other as we try to discuss a question of some philosophical complexity. Almost certainly, no matter which position we take, we will say some things that appear superficially contradictory (like Jesus and Paul did!). We must be gracious with each other while pushing for greater accuracy and clarity.

This post has uncovered points that will require further consideration. That said, I want to end by underscoring my main point in this post: Everything Jesus has said thus far in his conversation with the Pharisees (Matthew 19:3-6) suggests we should take Jesus’ command in its most natural, comprehensive sense: Humans can indeed dissolve the union that God creates in marriage, but they must not do so.


Will further evidence override this conclusion? In my next posts I plan to continue walking through Matthew 19, looking for more clues to what Jesus believed about marriage permanence.

I invite your prayers for my continued study and writing. Thank you for reading my words here, and feel free to add your insights in the comments below.

This eliminates the possibility, at least according to Mark’s version of events, that the Pharisees would have deduced from Jesus’ adultery statement that marriage was—contrary to all their understandings as Jews—indissoluble.

Hyper-Literalism, Could vs. Should, and a Guiding Question (JDR-2)

Before I begin discussing Jesus’ words on divorce and remarriage, I want to clarify a few things about my approach. In this post I’ll make two points about interpreting the Bible on the topic of divorce and remarriage:

  • First, I’ll discuss the futility of taking a hyper-literal approach.
  • Second, I’ll propose one point of confusion in Bible interpretation that divides “liberal” and “conservative” camps.[1]

Finally, I’ll use this second point to introduce the question that will guide me as I examine Jesus’ words in forthcoming posts.

Hyper-Literal Bible Interpretation

I want to begin by emphasizing, as strongly as possible, something that I think is utterly essential to acknowledge: Understanding the NT teaching on divorce and remarriage is not as simple as just taking the words of Jesus and Paul at face value. In fact, if one takes a hyper-literal approach to all the NT teachings on divorce—taking them all as universally-true statements, without any exception—then one ends up with multiple contradictions.

Here are just three examples:

  • Jesus said, “What therefore God has joined together, let not man separate” (Matt. 19:6). On face value, in the minds of most readers, this leaves no room for divorce, period. But Jesus also said, “Whoever divorces his wife, except for sexual immorality, and marries another, commits adultery” (Matt. 19:9). Debates of theologians aside, most people reading that for the first time would conclude that divorce is permitted for a husband whose wife has been sexually unfaithful. Which is true?
  • Matthew 19:9 includes the exception noted above. But Mark 10:11, which records the same historical event as Matthew, has Jesus condemning divorce without exception: “Whoever divorces his wife and marries another commits adultery against her.” Full stop. So, did Jesus give an exception or didn’t he?
  • Paul wrote, “If any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her” (1 Cor. 7:12). Wait a minute: What does Paul mean by “if…she consents to live with him”? Doesn’t that condition contradict Jesus’ unqualified prohibitions of divorce?

The debate over whether the NT ever permits remarriage, then, cannot be reduced to a debate between those who, in simple faith, take the Bible’s teachings at face value and those who, with hardened hearts, try to weasel around its clear teaching. (Simple faith and hard hearts, of course, do play important roles.) Rather, I suggest, it is more foundationally a debate over which of the Bible’s statements about divorce have the best claim to be taken at face value, without qualification—the prohibitions (almost always general statements[2]) or the exceptions (always directed to specific circumstances).

Again, no one takes all the NT divorce teachings at face value, as being universally true without qualification. It is impossible to do so. And because it is impossible, God clearly did not intend for us to do so. We are misunderstanding him, somewhere, if we try to do so.

With those facts clearly before us, we should free each other for an honest, humble discussion about how best to synthesize the Bible’s varied teachings on divorce.

Should Versus Could

How do Christians end up with such different perspectives on divorce and remarriage? One reason, of course, is that they disagree about which texts should control our reading of other texts. (See above.)

Another underlying cause for disagreement between “liberal” and “conservative” camps, it seems to me, is that one emphasizes the “could” of Scripture while the other emphasizes the “should.” The only way to read Scripture well, however, is to appropriately acknowledge both. Let me explain.

A “liberal” approach to divorce and remarriage emphasizes the passages of Scripture that say a marriage could be ended, whether rightly or wrongly. Since it is clear that marriage is not necessarily permanent, it must not be necessary to try to make it permanent, right? (Wrong.) This approach sometimes cites the divorce exceptions of Jesus and Paul (Matt. 19:9; 1 Cor. 7:15), but, in truth, finding specific biblical grounds for divorce is no longer very important. What really matters is just the basic fact that a marriage could come to an end. Such endings may be unfortunate, but they are to be expected and we should just try to navigate them with as much grace as possible, moving on to better relationships when old ones fade.

A ”conservative” approach, in contrast, emphasizes those Scriptures that say a marriage should never be ended by anything besides death. Since it is clearly necessary for marriage to be permanent, marriage must necessarily be permanent, right? (Wrong.) This approach acknowledges that some Scriptures seem to talk about marriages ending, but it quickly overrides all such texts with other passages that seem to indicate that even when a marriage is formally ended by divorce, obligations remain. These passages mentioning obligations are then universalized to apply to all divorce situations, no matter what exceptions may appear in a face-value reading of other Scriptures. Thus, any remarriage is always an “adulterous marriage,” or perhaps should not be called a marriage at all.

Neither approach, it seems to me, reads Scripture fairly.

To be honest, I’ve never been seriously tempted by the “liberal” approach. It shows utter disregard for God’s word and for basic human fidelity, despite the apparently loving motives of some who promote it.

The “conservative” approach, however, is more or less what I grew up with. (Please be patient with my simplistic summaries.) Because I this is the approach I have been taught for most of  my life, it is the position I will test in my forthcoming posts.

Did Jesus Teach That Marriage Is Indissoluble?

The basic question I’ll consider in my posts is this: Did Jesus believe that nothing besides death can truly end a marriage? Did he believe that marriage is indissoluble?

I’ll begin with the NT’s fullest account of Jesus’ teaching on the subject, found in Matthew 19. I’ll start by examining several of his “should statements” about the permanence of marriage, statements that are sometimes misinterpreted, it seems to me, as proof that a marriage could never be fully broken. After discussing key excerpts from Matthew 19, I’ll aim to synthesize Jesus’ other teachings, too. Throughout, I will focus on my basic question: Did Jesus believe marriage is indissoluble?

This series, then, will not try to address the rights and wrongs of every imaginable potential divorce situation. Rather, I’m testing a more foundational point. If Jesus really did believe a validly-contracted marriage cannot be dissolved by anything but death, then the “conservative” approach is fundamentally correct and all apparent exceptions must be read as not truly being exceptions after all.

But if we discover that Jesus never actually said anything that indicates he thought marriage is indissoluble, then this shapes how we must read what he did say. It means we have no reason to preclude, with the “conservative” approach, that Jesus’ exceptions cannot be taken at face value.

This series, then, is more about testing a key assumption many readers bring to Jesus’ words than it is about expounding the full meaning and significance of Jesus’ divorce teachings as might be done in a sermon. It is about testing the starting point of our thinking rather than trying to give a lot of practical guidance or application of Scripture to human life. That said, what I plan to share is anything but just theoretical. Answering the question Did Jesus believe marriage is indissoluble? is just about the most relevant thing I can imagine for anyone who is dealing with a marriage that is currently on the rocks.

Before we begin digging into this question, however, I want to emphasize as strongly as I can that Jesus’ main message about marriage was persistent and clear: God intends marriage to be for life, and any time a marriage union is separated, that marriage has fallen short of God’s creation design. Period. This was the heartbeat of Jesus’ teaching on divorce, and it must be the heartbeat of the church’s teaching, too, when taken as a whole.

My inquiry does not question this divine purpose at all. Rather, it focuses on what happens when humans fail to live up to it. Is it possible for humans to separate what God has joined? And is it possible for one marriage to end, other than by death, in such a way that remarriage may be an option that God blesses?

In short, my posts will address the question of what could happen to a marriage if it falls short of what God’s word clearly shows should happen.


I have one more post to share before I dig into Jesus’ words. In my next post I’ll summarize the general perspective on marriage permanence that I have reached after my study on this topic over the past couple of years. I call this perspective “radical faithfulness,” and I’ll contrast it with the positions I’ve called “liberal” and “conservative” in this post.

Meanwhile, I’d like to hear from you.

What are your thoughts on a hyper-literal approach to the NT teachings on divorce and remarriage? Have you observed confusion between the “should” and “could” of Scripture on this topic? What parts of Jesus’ teaching on the topic do you hope I dig into as I investigate Jesus’ view on marriage permanence?

Thanks for reading!

[1] I’m using scare quotes because I’m not attempting to precisely define, identify, or affirm either group. In my usage here, “liberal” simply means more permissive of divorce and “conservative” less permissive. Readers will have differing opinions on which position, if either, best conserves biblical doctrine and God’s liberal grace.

[2] I say “almost” because the prohibition in 1 Corinthians 7:11 is tied to a specific circumstance.
