Sexuality is often misunderstood in modern culture, but the Bible provides a clear and beautiful vision of the body and its purpose in marriage. St. John Paul II’s Theology of the Body (TOB) builds on biblical teachings to show that our bodies are not just physical structures, but sacred gifts meant to express God’s love.
What does the Bible teach about the human body, sexuality, and marriage? Let’s explore.
1. The Human Body Is Created in God’s Image
The Bible begins with a fundamental truth:
“God created mankind in His own image, in the image of God He created them; male and female He created them.” (Genesis 1:27)
This means that our bodies are not accidental or meaningless—they are part of God’s divine plan. Male and female are created to complement each other, reflecting God’s nature through their unity.
Reflection Question:
- Do I see my spouse’s body as a gift from God?
2. Marriage Is a Covenant, Not Just a Contract
Modern society often treats marriage as a temporary arrangement, but the Bible teaches that marriage is a sacred covenant:
“For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.” (Ephesians 5:31)
Becoming “one flesh” is more than a physical reality—it is a spiritual bond. TOB emphasizes that marital intimacy is meant to express total self-giving love, just as Christ gave Himself for the Church.
Practical Application:
- See intimacy as an act of love and commitment, not just a physical experience.
3. Sexuality Is a Holy Expression of Love
The Bible presents sexuality as a sacred gift, meant to be enjoyed within marriage:
“Let marriage be held in honor among all, and let the marriage bed be undefiled.” (Hebrews 13:4)
This means:
Sex is not dirty or shameful, but a reflection of divine love.
It must be lived with purity, respect, and self-giving.
It is not about selfish pleasure, but about unity and love.
Reflection Question:
- Do I approach marital intimacy with love and reverence, or with selfishness?
4. The Bible Condemns Lust and Infidelity
While the Bible praises sexuality in marriage, it warns against lust, infidelity, and impurity:
“You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.” (Matthew 5:27-28)
TOB teaches that lust distorts love, turning a person into an object instead of a gift. Faithfulness in marriage requires purity of heart and self-control.
Practical Application:
- Avoid anything that distorts love, such as pornography or emotional infidelity.
5. Love in Marriage Reflects Christ’s Love for the Church
The ultimate biblical teaching on marriage is that it mirrors Christ’s love for the Church:
“Husbands, love your wives, just as Christ loved the Church and gave Himself up for her.” (Ephesians 5:25)
This means that:
Husbands and wives are called to sacrifice for one another.
Marriage is about serving, not controlling.
Love must be faithful, unconditional, and life-giving.
Reflection Question:
- How can I love my spouse more like Christ loves the Church?
Living Out the Bible’s Teachings on the Body and Sexuality
To apply these biblical principles in marriage, couples must:
Respect and honor each other’s bodies.
Live intimacy as a gift, not a demand.
Remain faithful in thought and action.
See marriage as a sacred covenant, not a contract.
By following these teachings, marriage becomes not just a human relationship, but a divine reflection of God’s love.
