Matt 19:1–12 — What God Has Joined Together

Matthew 19 begins a new section of the Gospel. The transition appears in the opening words: “When Jesus had finished these sayings.” Matthew uses a similar formula after each of five major blocks of Jesus’ teaching: the Sermon on the Mount, the mission discourse, the kingdom parables, the teaching on community in Matthew 18, and the eschatological discourse near the end of the Gospel.

Jesus has now completed his Galilean ministry and begins his final journey toward Jerusalem. There he will be betrayed, arrested, tried, handed over to the Gentiles, crucified, and raised, just as he has repeatedly told his disciples.

Matthew 19–20 records Jesus teaching the countercultural values of the kingdom under the shadow of the cross. He will explain that wealth may obstruct faith rather than prove God’s favor: “Only with difficulty will a rich person enter the kingdom of heaven.” He will declare that many who are first will be last and the last first. When the mother of James and John seeks places of honor for her sons, Jesus will teach that greatness consists in humble service, just as the Son of Man came not to be served but to serve and give his life as a ransom for many.

The present passage belongs within this pattern. Although the Pharisees initiate the discussion, the disciples’ reaction becomes its focus. Jesus teaches them the kingdom’s countercultural values concerning marriage, divorce, and singleness.

The Pharisees’ Test

The Pharisees approach Jesus and ask, “Is it lawful to divorce one’s wife for any cause?” They are inviting him to enter a prominent debate between two Jewish schools of thought.

The school of Hillel permitted divorce for trivial reasons. A man might divorce his wife because she burned a meal, used too much salt, or no longer pleased him. The school of Shammai allowed divorce only for some form of sexual sin.

Their disagreement centered upon Deuteronomy 24:1:

When a man takes a wife and marries her, if then she finds no favor in his eyes because he has found some indecency in her …

The Hebrew expression “some indecency” is unclear. The Shammaites emphasized that phrase and interpreted it narrowly, although some included behavior such as immodest dress. The Hillelites emphasized the preceding words, “she finds no favor in his eyes,” and permitted divorce for virtually anything the husband found objectionable.

Jesus refuses the terms of their debate. Both schools begin with divorce and argue about how permissive its grounds should be. Jesus begins with creation.

The Creation Standard

Jesus answers:

Have you not read that he who created them from the beginning made them male and female, and said, “Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh”? So they are no longer two but one flesh. What therefore God has joined together, let not man separate.

He first quotes Genesis 1:27: the Creator made humanity male and female. He then quotes Genesis 2:24 concerning the man who leaves father and mother, holds fast to his wife, and becomes one flesh with her.

An important point appears in the words “and said.” Grammatically, the subject is “he who created them”—God. Yet Genesis 2:24 is spoken by the narrator of Genesis rather than introduced as a direct quotation from God. Jesus treats the narrator’s words as the Creator’s own speech. This reflects his high view of Scripture’s inspiration, authority, and truthfulness.

The conclusion is decisive: “What therefore God has joined together, let not man separate.” The verb translated “joined together” is connected with the man’s holding fast to his wife. It suggests that God has fastened or welded the two together. Marriage is not merely a human contract that its parties may dissolve whenever it becomes inconvenient. God creates the one-flesh bond.

Moses and Hardness of Heart

The Pharisees respond, “Why then did Moses command one to give a certificate of divorce and to send her away?” Their wording misrepresents Deuteronomy 24. Moses did not command divorce; he regulated and permitted it.

Jesus replies, “Because of your hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so.” Deuteronomy’s provision is a concession to human sinfulness. It curbs and limits sin within a fallen society. The passage itself concludes by warning Israel not to bring sin upon the land God gives as an inheritance.

When discussing divorce, we are tempted to begin too low. We immediately ask which grounds are permissible and then debate degrees of wrongdoing. Jesus begins with God’s purpose and only afterward addresses the concessions required by human hardness of heart. He calls us back to the creation ordinance and forward to its fulfillment in the new creation.

Marriage is not chiefly about personal convenience or happiness. It is God’s institution for God’s purposes and must not be set aside lightly. Jesus therefore says:

Whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.

Celibacy for the Kingdom

The disciples respond, “If such is the case of a man with his wife, it is better not to marry.” Their reaction reveals how deeply they share the prevailing assumption that marriage exists for a man’s convenience. If a husband cannot easily escape an unsatisfying marriage, they reason, perhaps he should avoid marriage altogether.

Jesus answers, “Not everyone can receive this saying, but only those to whom it is given.” What is “this saying”? It cannot refer to his teaching about the permanence of marriage, as though that moral standard applied only to people capable of accepting it. Jesus would then retreat from his own authoritative command.

Rather, “this saying” refers to the disciples’ immediately preceding statement that it may be better not to marry. Celibacy is not given to everyone. Paul makes the same point in 1 Corinthians 7: “Each has his own gift from God.”

Jesus explains:

There are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven.

Some people are physically incapable of procreation from birth. Others were made eunuchs, a common ancient practice among servants entrusted with royal harems. A third group voluntarily embraces celibacy for the sake of God’s kingdom. Jesus is not describing literal self-mutilation but the deliberate choice not to marry in order to fulfill a particular calling in Christ’s service.

The disciples are therefore right in one limited sense: for a particular person, singleness may be better—but not because marriage is an inconvenient bond. It may be better because God has granted that person freedom from worldly cares and a special opportunity for kingdom service.

Paul states clearly in 1 Corinthians 7 that marriage is not sinful. Yet singleness can provide fewer domestic and financial anxieties and greater freedom to serve Christ with “undivided devotion.” Both marriage and celibacy honor the kingdom when received as callings from God.

The Essence of Marriage

This passage first teaches us the essence of marriage—what marriage fundamentally is. Drawing upon Genesis 1–2, Jesus presents marriage as a one-flesh sexual union between a man and a woman, established by God and oriented toward children.

The orientation toward children is implied by the male-female union and by the creation mandate that immediately follows Genesis 1:27: “Be fruitful and multiply.” Biological complementarity belongs to the created form of marriage even when a particular marriage does not produce children.

Most importantly, God establishes the union. Marriage is more than a revocable agreement between consenting adults. God joins one man and one woman at physical, emotional, and spiritual levels. Because he forms that bond, its participants are not free to dissolve it at will.

Married Christians honor this ordinance through fidelity and perseverance. Unmarried Christians honor it through chastity. Both recognize marriage as holy and submit their sexuality to the Creator’s design.

How Christians Should View Divorce

The prevailing assumption among many Jewish men was that marriage served their satisfaction. If a wife no longer pleased her husband, divorce was treated as his right. Jesus overturns that assumption. Marriage is God’s ordinance, not an arrangement governed by individual happiness.

Husbands and wives should therefore make every reasonable effort to preserve their marriage, including during seasons of real unhappiness. No one may simply declare, “I have had enough; I will no longer work toward reconciliation because my happiness requires me to leave.”

Jesus reframes the question. Instead of beginning by asking which grounds establish a right to divorce, Christians should begin with the permanent bond God has created. In that basic sense, no one possesses an autonomous right to separate what God has joined.

Jesus nevertheless acknowledges that divorce occurs in a fallen world. He identifies sexual immorality as an exception. The sermon’s understanding is that this means persistent, unrepentant marital unfaithfulness that has itself ruptured the covenant bond. In such a case, divorce legally acknowledges a breach already effected by the unfaithful spouse.

Paul identifies a second situation in 1 Corinthians 7:10–16. In a marriage between a believer and an unbeliever, if the unbelieving spouse insists upon leaving, the believer should let that person depart. The believer is “not enslaved” and may remarry, though only to another believer.

These exceptions recognize the destructive reality of sin; they do not replace Jesus’ starting point. Christians must not fixate upon legal technicalities while forgetting that marriage is a one-flesh union God intends to endure.

Thinking from Creation

Finally, Jesus models how Christians should approach other questions concerning marriage and sexuality. The Pharisees could have asked whether a man may have multiple wives, pointing to Abraham, Jacob, or David. Jesus’ method would still lead back to the creation standard: one man and one woman joined as one flesh.

The same method applies to modern questions about same-sex relationships or attempts to reject and alter one’s biological sex. Christians should not begin with the preferences of the surrounding culture but with the Creator’s design revealed in Genesis and reaffirmed by Christ.

Jesus calls his people beyond arguments over how far they may depart from that design. The kingdom summons us toward the high standard of creation renewed under the shadow of the cross. Married and single believers alike must place the kingdom above personal convenience, receive their calling from God, and honor the good order he established for human flourishing.
