Marriage, family, and sexuality

Conscience, relationships, and witness

Family teaching becomes distorted when it gives one person authority without the responsibilities Scripture attaches to it. Biblical marriage calls for faithfulness, self-giving love, and honorable conduct. It also belongs within a wider account of sexual holiness and human dignity. A correct view of marriage should make mistreatment harder to justify, not provide it with more religious vocabulary.

Read Genesis 2:15-25

15 The LORD God took the man, and put him into the garden of Eden to cultivate and keep it.
16 The LORD God commanded the man, saying, “You may freely eat of every tree of the garden;
17 but you shall not eat of the tree of the knowledge of good and evil; for in the day that you eat of it, you will surely die.”
18 The LORD God said, “It is not good for the man to be alone. I will make him a helper comparable to him.”
19 Out of the ground the LORD God formed every animal of the field, and every bird of the sky, and brought them to the man to see what he would call them. Whatever the man called every living creature became its name.
20 The man gave names to all livestock, and to the birds of the sky, and to every animal of the field; but for man there was not found a helper comparable to him.
21 The LORD God caused the man to fall into a deep sleep. As the man slept, he took one of his ribs, and closed up the flesh in its place.
22 The LORD God made a woman from the rib which he had taken from the man, and brought her to the man.
23 The man said, “This is now bone of my bones, and flesh of my flesh. She will be called ‘woman,’ because she was taken out of Man.”
24 Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh.
25 The man and his wife were both naked, and they were not ashamed.

The creation account presents companionship and union before the fall. Later biblical narratives describe polygamy and other distortions without making every recorded practice the ideal. Jesus returns to the creation pattern when discussing marriage. That gives the relationship a standard beyond convenience. The one-flesh union is not merely a temporary arrangement that lasts until one party discovers a preferred alternative. It involves fidelity and a bond to be treated with moral seriousness.

Read Ephesians 5:21-33

21 subjecting yourselves to one another in the fear of Christ.
22 Wives, be subject to your own husbands, as to the Lord.
23 For the husband is the head of the wife, as Christ also is the head of the assembly, being himself the savior of the body.
24 But as the assembly is subject to Christ, so let the wives also be to their own husbands in everything.
25 Husbands, love your wives, even as Christ also loved the assembly and gave himself up for her,
26 that he might sanctify her, having cleansed her by the washing of water with the word,
27 that he might present the assembly to himself gloriously, not having spot or wrinkle or any such thing, but that she should be holy and without defect.
28 Even so husbands also ought to love their own wives as their own bodies. He who loves his own wife loves himself.
29 For no man ever hated his own flesh, but nourishes and cherishes it, even as the Lord also does the assembly,
30 because we are members of his body, of his flesh and bones.
31 “For this cause a man will leave his father and mother and will be joined to his wife. Then the two will become one flesh.”
32 This mystery is great, but I speak concerning Christ and the assembly.
33 Nevertheless each of you must also love his own wife even as himself; and let the wife see that she respects her husband.

The husband is commanded to love in the pattern of Christ giving Himself for the church. That is a demanding responsibility, not a decorative introduction to personal privilege. The historic complementary-role understanding adopted here does not make one spouse less human or less valuable before God. Both answer to Christ. A person who uses the passage to demand submission while refusing sacrificial love is selecting the part that benefits him and evading the part addressed to him.

Read 1 Corinthians 6:9-20

9 Or don’t you know that the unrighteous will not inherit God’s Kingdom? Don’t be deceived. Neither the sexually immoral, nor idolaters, nor adulterers, nor male prostitutes, nor homosexuals,
10 nor thieves, nor covetous, nor drunkards, nor slanderers, nor extortionists, will inherit God’s Kingdom.
11 Some of you were such, but you were washed. You were sanctified. You were justified in the name of the Lord Jesus, and in the Spirit of our God.
12 “All things are lawful for me,” but not all things are expedient. “All things are lawful for me,” but I will not be brought under the power of anything.
13 “Foods for the belly, and the belly for foods,” but God will bring to nothing both it and them. But the body is not for sexual immorality, but for the Lord, and the Lord for the body.
14 Now God raised up the Lord, and will also raise us up by his power.
15 Don’t you know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a prostitute? May it never be!
16 Or don’t you know that he who is joined to a prostitute is one body? For, “The two”, he says, “will become one flesh.”
17 But he who is joined to the Lord is one spirit.
18 Flee sexual immorality! “Every sin that a man does is outside the body,” but he who commits sexual immorality sins against his own body.
19 Or don’t you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own,
20 for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God’s.

Paul names conduct incompatible with the kingdom and then reminds believers that some of them had lived that way. Cleansing and change are real. Biblical sexual teaching should therefore combine moral clarity with the possibility of redemption. It should not turn a person’s history into an unchangeable sentence. The body belongs to Christ, so sexual choices cannot be reduced to private preference. Desire is significant, but it does not independently establish what is right.

Read 1 Corinthians 7:1-16

1 Now concerning the things about which you wrote to me: it is good for a man not to touch a woman.
2 But, because of sexual immoralities, let each man have his own wife, and let each woman have her own husband.
3 Let the husband give his wife the affection owed her, and likewise also the wife her husband.
4 The wife doesn’t have authority over her own body, but the husband does. Likewise also the husband doesn’t have authority over his own body, but the wife does.
5 Don’t deprive one another, unless it is by consent for a season, that you may give yourselves to fasting and prayer, and may be together again, that Satan doesn’t tempt you because of your lack of self-control.
6 But this I say by way of concession, not of commandment.
7 Yet I wish that all men were like me. However, each man has his own gift from God, one of this kind, and another of that kind.
8 But I say to the unmarried and to widows, it is good for them if they remain even as I am.
9 But if they don’t have self-control, let them marry. For it’s better to marry than to burn with passion.
10 But to the married I command—not I, but the Lord—that the wife not leave her husband
11 (but if she departs, let her remain unmarried, or else be reconciled to her husband), and that the husband not leave his wife.
12 But to the rest I—not the Lord—say, if any brother has an unbelieving wife, and she is content to live with him, let him not leave her.
13 The woman who has an unbelieving husband, and he is content to live with her, let her not leave her husband.
14 For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the husband. Otherwise your children would be unclean, but now they are holy.
15 Yet if the unbeliever departs, let there be separation. The brother or the sister is not under bondage in such cases, but God has called us in peace.
16 For how do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?

Paul treats singleness with respect and recognizes obligations within marriage. Neither state removes the call to self-control and service. His discussion of separation and desertion also shows why difficult family cases should not be answered by one isolated slogan. Christians differ about the precise scope of divorce and remarriage permissions, but no interpretation should require calling abuse loving or danger safe. Fidelity to Scripture includes hearing the actual circumstances and applying the relevant passages accurately.

Apply the teaching first to your own obligations. Honor marriage, practice sexual self-control, and treat family members with truth and patience. Respect those who are single rather than treating marriage as the entrance requirement for a complete Christian life. The household should be a place where the Lord’s character is made easier to recognize.

Consider your perspective

Biblical family responsibilities call each person to faithfulness and self-giving, not merely to monitoring another person's duties. Equal dignity, the honor of singleness, and protection from abuse belong within faithful Christian teaching about marriage and sexuality.

Put it into practice

Focus on the responsibility addressed to you in one relationship. Choose a concrete act of truthful care, and support appropriate safety and accountability wherever harm is being excused in the name of authority.

Reflect and respond

• Are you applying the command addressed to you or only the one addressed to someone else?
• How can a church honor unmarried believers?
• What practice would make a household more truthful and safe?
