Introduction

During a visit to the hospital, a nurse asked us about concubinage. Basing herself on various pieces of information and on certain religious convictions, she believed she was living in sin. This discussion, centered on what the Bible really teaches on this subject, prompted the creation of this study.

We wish to examine carefully what the Scriptures say about marriage, about the union between a man and a woman, and about concubinage. Since the Bible presents itself as the word of God (2 Timothy 3.16), it seems essential to us to seek its teaching seriously, without limiting ourselves to human traditions or personal opinions.

The aim of this study is therefore to analyze the various biblical texts relating to marriage, to the couple’s commitment and to sexuality, in order to understand how the biblical authors view the marital relationship. We will also seek to determine whether the modern notion of concubinage corresponds, or not, to the model presented in the Scriptures.

From the very first chapters of the Bible, the union between man and woman appears as an institution willed by God:

Genesis 2.24 (King James Version) :
Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

Jesus himself takes up this passage when he teaches about marriage:

Matthew 19.5-6 (King James Version) :
And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.

The New Testament also speaks of the need for moral conduct in human and sexual relationships:

Hebrews 13.4 (King James Version) :
Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.

However, the Bible also presents varied and sometimes complex family situations: polygamy, repudiation, widowhood, irregular unions, or the absence of an explicitly described religious ceremony. These elements therefore call for a careful study of the historical, cultural and biblical context in order to avoid hasty conclusions.

Our approach is not to condemn people, but to understand biblical teaching faithfully as a whole, with humility and balance.

I. The union of a man and a woman according to the Bible

The expression “the union of a man and a woman according to the Bible” refers mainly to the biblical conception of marriage, as it gradually appears in the Scriptures, from the creation in Genesis to the teachings of Jesus and the apostles.

1- The original model in Genesis

The Bible presents the union between man and woman as an institution willed by God from the creation:

Genesis 2.24 (King James Version) :
Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

This verse is fundamental. It contains several important ideas:

  • a separation from the parental home;
  • a lasting attachment;
  • a deep union described as “one flesh.”

In this context, the marital union is not only sexual or social; it also has a spiritual dimension and the dimension of a covenant.

2- Jesus confirms this model

Jesus directly takes up this text when he teaches about marriage:

Matthew 19.4-6 (King James Version) :
And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female,And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.

He emphasizes:

  • the divine origin of marriage;
  • the unity of the couple;
  • the lasting nature of this union.

For Jesus, the reference model remains that of the creation.

3- Marriage in the biblical context

In the Bible, marriage is not always described by a precise religious ceremony as in modern traditions. However, several elements recur regularly:

  • public commitment;
  • a covenant between two families;
  • faithfulness;
  • life together;
  • sexual relations reserved for the marital setting.

Sexuality is presented as linked to this union:

II. Concubinage and unions outside marriage

Hebrews 13.4 (King James Version) :
Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.

The modern notion of “concubinage” does not appear directly in contemporary biblical terms. However, the Scriptures generally condemn sexual relations outside the recognized framework of the marital union (Hebrews 13.4; 1 Corinthians 7.2; Ephesians 5.3).

The New Testament often uses the Greek term porneia, translated in various versions as:

  • sexual immorality;
  • impurity;
  • fornication.

This term appears in many important passages (Matthew 15.19; Mark 7.21; Acts 15.20; 1 Corinthians 5.1; Galatians 5.19; Colossians 3.5).

For example:

1 Corinthians 6.18 (King James Version) :
Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body.

or again:

1 Thessalonians 4.3 (King James Version) :
For this is the will of God, even your sanctification, that ye should abstain from fornication:

Paul also adds:

1 Corinthians 7.2 (King James Version) :
Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.

The New Testament also reminds us:

Hebrews 13.4 (King James Version) :
Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.

Jesus himself places the marital union within the framework of God’s original plan:

Matthew 19.5 (King James Version) :
And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?

see also:

Genesis 2.24 (King James Version) :
Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

The difficulty often lies in the exact definition of what biblically constitutes a valid marriage:

  • a mere sexual relationship? (1 Corinthians 6.16)
  • an official commitment?
  • a public covenant? (Malachi 2.14)
  • social recognition? (John 4.16-18)
  • a religious blessing?

Indeed, the Bible sometimes presents marriage as a true covenant:

Malachi 2.14 (King James Version) :
Yet ye say, Wherefore? Because the LORD hath been witness between thee and the wife of thy youth, against whom thou hast dealt treacherously: yet is she thy companion, and the wife of thy covenant.Noteresidue: or, excellencyNotegodly…: Heb. seed of GodNotetreacherously: or, unfaithfullyNotethat he…: or, if he hate her, put her awayNoteputting…: Heb. to put away

The biblical accounts also show that unions generally enjoyed family or community recognition:

  • Isaac officially receives Rebekah as his wife (Genesis 24.67);
  • Jacob serves Laban to obtain Rachel (Genesis 29.18-28);
  • the presuppose a public celebration (John 2.1-2).

However, the biblical texts do not always answer these questions in a modern or legal way, which explains the debates among Christian interpretations. The forms of marriage also varied according to the biblical periods and cultural contexts (Deuteronomy 24.1-4; Matthew 19.8).

Thus, the Scriptures seem to emphasize rather:

  • faithfulness (Malachi 2.14-15; Hebrews 13.4);
  • the stability and permanence of the union (Genesis 2.24; Matthew 19.5-6);
  • real commitment and the covenant between the spouses (Malachi 2.14; Ephesians 5.31);
  • moral purity (1 Thessalonians 4.3-4; 1 Corinthians 6.18);
  • and mutual responsibility within the couple (Ephesians 5.25-33; 1 Corinthians 7.3-5),

than on the existence of a precisely defined universal administrative procedure. Indeed, the Bible never describes a single, mandatory model of ceremony or legal registration applicable to all periods and all cultures.

III. A more complex reality in the Old Testament

The Old Testament also describes complex family situations:

  • polygamy (Abraham: Genesis 16.1-4; Jacob: Genesis 29.23-30; David: 2 Samuel 5.13; Solomon: 1 Kings 11.1-3);
  • concubines (Judges 19.1-2; 2 Samuel 5.13);
  • repudiation (Deuteronomy 24.1-4);
  • arranged marriages (Genesis 24.1-4; Genesis 24.50-51);
  • levirate marriage (Deuteronomy 25.5-10).

However, the Bible sometimes describes these practices without necessarily approving them morally. Many accounts even show the tensions, conflicts and painful consequences that flow from these situations:

  • rivalry between Sarah and Hagar (Genesis 16.4-6);
  • conflicts between Leah and Rachel (Genesis 30.1-8);
  • family tragedies in the house of David (2 Samuel 13.1-29);
  • the turning away of Solomon’s heart by his many foreign wives (1 Kings 11.3-4).

Thus, several practices tolerated in the history of Israel seem to reflect an adaptation to the hardness of the rather than the initial ideal presented at the creation (Matthew 19.8).

IV. The example of the Samaritan woman

The encounter between the Messiah Jesus and the Samaritan woman at the well of Sychar is a particularly interesting passage in the context of this reflection on concubinage, irregular unions and the biblical conception of the couple (John 4.1-30).
This dialogue shows that Jesus clearly distinguishes a legitimate marital relationship from a mere life together or an unrecognized romantic relationship.

1- The context of the account

As he passes through Samaria, Jesus stops near Jacob’s well, close to the town of Sychar (John 4.5-6). A Samaritan woman comes to draw water, and Jesus starts a conversation with her despite the cultural tensions between Jews and (John 4.7-9).

The dialogue quickly takes on a spiritual dimension, then Jesus reveals a precise knowledge of this woman’s romantic situation:

2- An important distinction between marriage and free union

John 4.16-18 (King James Version) :
Jesus saith unto her, Go, call thy husband, and come hither.The woman answered and said, I have no husband. Jesus said unto her, Thou hast well said, I have no husband:For thou hast had five husbands; and he whom thou now hast is not thy husband: in that saidst thou truly.

This passage is remarkable because Jesus explicitly acknowledges two different realities:

  • the five previous men are called “husbands”;
  • the man with whom she is currently living “is not” her husband.

In other words, Jesus does not automatically regard mere cohabitation or sexual relations as equivalent to marriage.

This clarification is important in a study on concubinage, because it shows that in Jesus’ eyes:

  • living with someone is not enough to constitute a true marital union;
  • there is a difference between a relationship recognized as marriage and an irregular relationship.

The Greek text uses here the term anêr (“husband” or “spouse”), showing that Jesus is indeed speaking of marital status and not simply of a companion.

3- Jesus does not harshly condemn the woman

The account also shows Jesus’ remarkable attitude:

  • he reveals the truth;
  • he does not trivialize the situation;
  • but neither does he reject this woman.

On the contrary, he offers her a profound spiritual teaching about “living water” and true worship (John 4.10-24).
This approach illustrates the biblical balance between:

  • moral truth;
  • a call to repentance;
  • grace and mercy.

4- A probably complex situation

The text does not specify why this woman had five husbands:

  • successive deaths;
  • divorces;
  • repudiations;
  • or difficult social circumstances.

In the ancient world, a woman often depended economically on a man. Some situations could therefore be endured rather than chosen.

However, Jesus nevertheless stresses that her present relationship does not correspond to a true recognized marital union.

5- The relevance of this passage for a study on concubinage

This account can therefore be used to show several important biblical principles:

  1. Marriage has a special recognition

The Bible clearly distinguishes:

  • marriage;
  • and relationships outside this framework.

(Genesis 2.24 ; Matthew 19.4-6)

  1. Mere life together is not automatically equivalent to marriage

Jesus explicitly states:

John 4.18 (King James Version) :
For thou hast had five husbands; and he whom thou now hast is not thy husband: in that saidst thou truly.

This sentence is probably one of the most explicit passages of the New Testament on this question.

  1. Grace does not cancel the moral requirement

Jesus welcomes this woman with compassion, but without redefining her situation as legitimate.

  1. Salvation remains accessible

The Samaritan woman even becomes a witness afterward to the inhabitants of the town:

John 4.29 (King James Version) :
Come, see a man, which told me all things that ever I did: is not this the Christ?

Many then believed in Jesus because of her testimony (John 4.39-42).

V. A tension of interpretation today

Today, several approaches exist among believers:

  • some consider that only a civil or religious union constitutes a marriage;
  • others judge that a real and lasting commitment before God may suffice;
  • some insist above all on the faithfulness and stability of the couple;
  • others emphasize conformity to a precise ecclesial framework.

This is why a serious study of the subject requires:

  • examining the texts in their context;
  • a distinction between description and prescription;
  • reflection on the evolution of social structures between the biblical world and our own time.

These three principles form an important basis for approaching honestly the question of marriage and concubinage in the Scriptures. Indeed, certain biblical passages simply describe situations lived by characters without approving all their behavior. Thus, the presence of polygamy, concubines or certain particular unions in the Old Testament does not necessarily mean that these practices represent the ideal willed by God (Genesis 16.1-4; 1 Kings 11.1-4).

It is therefore essential to distinguish:

  • what the Bible reports historically;
  • and what it presents as a model or a moral teaching.

This distinction appears clearly when Jesus refers his hearers back to God’s original plan at the creation:

Mark 10.6 (King James Version) :
But from the beginning of the creation God made them male and female.

Christ thus shows that certain practices tolerated in the history of Israel sometimes resulted from the hardness of the (Matthew 19.8) and did not fully correspond to the original ideal.

Moreover, we must take into account the evolution of social structures between the biblical era and our modern world. In ancient societies, marriage often rested on family agreements, community commitments or publicly recognized covenants. Religious ceremonies as we know them today were not always described precisely in the biblical texts.

Furthermore, the contemporary notions of:

  • civil marriage;
  • free union;
  • PACS ;
  • legal concubinage;
  • life together without official commitment;
    did not exist in their present form in the ancient world. A simple, direct transposition of modern categories onto the biblical texts can therefore lead to imprecise conclusions.

The study must then seek to identify the great biblical principles that frame the union between man and woman:

  • faithfulness;
  • lasting commitment;
  • mutual responsibility;
  • moral purity;
  • respect for the covenant;
  • protection of the family.

The apostle Paul notably reminds us that the marital relationship has a profound and sacred dimension:

Ephesians 5.32 (King James Version) :
This is a great mystery: but I speak concerning Christ and the church.

Thus, beyond legal or cultural debates, the Bible seems to present the marital union as a serious, public and faithful covenant, called to reflect the relationship between God and his people.

VI. Would any union that respects biblical principles be suitable?

This is precisely one of the most delicate questions of the subject, for the Bible never gives a detailed legal definition of marriage comparable to our modern systems. The Scriptures present mainly general principles, while the social forms of marriage have varied according to the periods and cultures.

Two main approaches generally exist among readers of the Bible.

1- The approach that considers that a faithful union can constitute a biblical marriage

Some hold that the heart of biblical marriage lies mainly in:

  • lasting commitment;
  • faithfulness;
  • life together;
  • physical union (“one flesh”);
  • the couple’s social recognition.

From this perspective, a couple living together in a stable and faithful way could be considered married before God, even without a modern religious ceremony or a contemporary administrative document.

This idea rests notably on the fact that:

  • the Bible rarely describes detailed wedding ceremonies;
  • Adam and Eve had no official rite described (Genesis 2.24);
  • Isaac takes Rebekah into his tent and she becomes his wife (Genesis 24.67);
  • sexual union is presented as creating a form of deep unity (1 Corinthians 6.16).

According to this reading, the main problem would not be the absence of an administrative act, but rather:

  • the absence of real commitment;
  • instability;
  • multiple relationships;
  • or the deliberate refusal to publicly acknowledge one’s union.

2- The approach that clearly distinguishes free union from marriage

Others, however, consider that biblical marriage necessarily involves:

  • a publicly recognized covenant;
  • an explicit commitment;
  • family and social recognition;
  • sometimes a form of civil or religious authority.

They stress that, in the Bible, unions are generally known and recognized by the community. Marriage is not presented as a mere private cohabitation.

This approach also insists on the texts calling us to avoid “immorality” (1 Corinthians 7.2; Hebrews 13.4) and considers that sexual union finds its normal place within an officially acknowledged framework.

In this reading, modern concubinage is sometimes problematic because it can reflect:

  • an absence of definitive commitment;
  • a desire to keep a way out;
  • or a conscious refusal of the marriage covenant.

3- An important difficulty: our modern categories

The problem also comes from the fact that our modern notion of “free union” covers very different realities:

  • a couple stable for 40 years with children;
  • a temporary relationship without commitment;
  • a life together equivalent to a marriage;
  • mere emotional cohabitation.

Yet the Bible does not directly address these contemporary categories.

4- What seems central in the Scriptures

When we gather the various biblical texts, several elements appear essential:

  • faithfulness;
  • exclusivity;
  • lasting commitment;
  • mutual responsibility;
  • recognition of the union;
  • sincerity before God.

Thus, many debates concern the ceremony itself less than the reality of the commitment.

5- A prudent conclusion

It therefore seems difficult to state in an absolute manner:

  • either that every free union is automatically a sin;
  • or that it is always fully equivalent to biblical marriage.

Everything probably depends on what this union really involves:

  • mere cohabitation without commitment;
  • or a true covenant of faithful and acknowledged life together.

The Bible emphasizes above all the truth of the heart, faithfulness and moral responsibility rather than mere conformity to a modern administrative procedure. However, it also strongly values public and stable covenants, which explains why many believers regard officially recognized marriage as the form most in keeping with the spirit of the Scriptures.

VII. If a couple respects the biblical prescriptions, are they considered married in God’s eyes?

This is a possibility defended by some believers and theologians, but we must acknowledge that the Bible never explicitly formulates this conclusion directly. We are therefore obliged to reason from biblical principles rather than from a precise legal definition of marriage.

1- The obligation to submit to the laws

However, we are commanded to submit to the laws — meaning those of one’s own country:

“Let every person be subject to the governing authorities; for there is no authority except from God, and the authorities that exist have been instituted by God.”
— Romans 13.1

“Submit yourselves, for the Lord’s sake, to every authority instituted among men.”
— 1 Peter 2.13

In this area, marriage is part of the law and, moreover, goes back many decades. It celebrates, without any possible confusion, a covenant between a man and a woman, in accordance with the original design:

“Therefore a man shall leave his father and his mother and be joined to his wife, and they shall become one flesh.”
— Genesis 2.24

“Have you not read that the Creator, from the beginning, made them male and female, and said: Therefore a man shall leave his father and his mother and be joined to his wife, and the two shall become one flesh?”
— Matthew 19.4-5

Marriage thus clearly displays the principles we have noted: public commitment, exclusive faithfulness, a lasting union between a man and a woman.

2- Marriage: the only fully binding covenant

Consequently, even if other legislative and administrative arrangements might seem suitable, it clearly appears that marriage is the only covenant that fully binds the couple — before God, before men and before the law.

The apostle Paul, moreover, recalls the importance of formal commitment and good reputation:

“Aim at what is good, not only before the Lord but also before men.”
— 2 Corinthians 8.21

3- The other forms of union

The other forms recognized by French law — free union, concubinage, PACS — remain arrangements intended to frame other modes of covenant that depart from the biblical prescriptions. They include neither the solemn commitment nor the dimension of an exclusive and definitive covenant that the Bible associates with marriage.

Conclusion

This study shows that the Bible insists above all on the reality of the commitment between man and woman rather than on a single, universal administrative form. Modern legal structures — civil marriage, PACS, concubinage — did not exist in their present form in biblical times. The way of making a union official has, moreover, evolved considerably over the centuries and continues to vary according to cultures and legislations.

1- The fundamental biblical principles

Under these conditions, the essential question lies less in the administrative status itself than in respect for the fundamental biblical principles:

  • Faithfulness and exclusivity — a commitment reserved for one person only;
  • Durability — a covenant designed for an entire lifetime;
  • Mutual responsibility — reciprocal support in every aspect of life;
  • Sincerity before God — an upright heart and a pure intention;
  • Public recognition — a union openly acknowledged before men.

The Scriptures emphasize the truth of the heart and faithfulness to the covenant (Genesis 2.24; Matthew 19.5-6). Jesus himself reproached the religious leaders of his time for having multiplied human rules at the expense of the spirit of the Law (Mark 7.6-13).

2- Marriage: the form of union most in keeping with the Scriptures

However, we must acknowledge that marriage remains today the clearest form of union, the most publicly recognized, and the one least open to confusion.

The term “concubinage” covers very diverse realities: unstable relationships, temporary arrangements, but also sincere and lasting commitments. This ambiguity makes it hard to reconcile with the biblical requirement of clarity and public witness. Likewise, the PACS is above all a civil legal framework, originally designed for situations distinct from traditional marriage, and does not guarantee respect for scriptural principles.

3- Obedience to the laws: a biblical imperative

The Bible explicitly urges us to respect the laws established by the authorities:

“Let every person be subject to the governing authorities; for there is no authority except from God.”
— Romans 13.1

“Submit yourselves, for the Lord’s sake, to every authority instituted among men.”
— 1 Peter 2.13

In France, marriage is the legal institution that officially consecrates the union of a man and a woman in a public, solemn and binding framework. The other forms of union — free union, concubinage, PACS — were designed to meet other situations and are addressed to other categories of people. They depart from the objectives set by the Scriptures: an exclusive, definitive and public covenant between a man and a woman (Genesis 2.24; Hebrews 13.4).

4- Marriage: the path to favor

Thus, given this twofold imperative — to respect the divine principles and to submit to the laws of the country — marriage appears as the only option that fully meets the biblical criteria.

This is why we strongly encourage Christian couples to choose the path of marriage. Not out of legalism or social conformity, but because this covenant best reflects God’s design for man and woman. Marriage offers a clear, public and solemn framework that honors God, protects the couple and bears witness before men to the beauty of faithful commitment.

The apostle Paul, moreover, raises marriage to the rank of a sacred mystery, an image of the union between Christ and the Church:

“Therefore a man shall leave his father and his mother and be joined to his wife, and the two shall become one flesh. This mystery is great; but I speak concerning Christ and the Church.”
— Ephesians 5.31-32

By choosing marriage, the Christian couple does not merely comply with a formality: it performs an act of faith, a visible testimony of its commitment before God and before men.

5- A kindly invitation

This study does not claim to condemn those who live in different situations, nor to settle definitively a subject on which opinions remain divided within the Christian world. Every journey is unique, and God knows hearts.

However, for those who seek to honor God in their life as a couple, marriage remains the surest, the clearest and the most Scripture-conforming path. It is a path of blessing that we encourage you to take with joy and confidence.

For beyond legal frameworks, God looks above all at the heart: the sincerity, faithfulness and truth of human commitment (1 Samuel 16.7).
