Marital fidelity is a central tenet in the biblical understanding of marriage, reflecting the covenantal relationship between husband and wife. This concept is deeply rooted in the Scriptures, where marriage is portrayed as a sacred institution established by God. The seriousness of marital fidelity is underscored throughout the Bible, emphasizing the importance of faithfulness, trust, and commitment between spouses.

Biblical Foundation

The foundation for marital fidelity is established in the creation narrative. In Genesis 2:24 , it is written, "For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh." This verse highlights the unique and exclusive bond between husband and wife, signifying a union that is both physical and spiritual. The "one flesh" concept underscores the depth of intimacy and commitment expected in marriage.

The Seventh Commandment

The seriousness of marital fidelity is further emphasized in the Ten Commandments. Exodus 20:14 states, "You shall not commit adultery." This commandment explicitly prohibits adultery, underscoring the sanctity of the marital relationship. Adultery is seen as a grave sin that violates the covenant between spouses and disrupts the divine order established by God.

Wisdom Literature

The wisdom literature of the Old Testament also addresses the importance of marital fidelity. Proverbs 5:18-19 advises, "May your fountain be blessed, and may you rejoice in the wife of your youth. A loving doe, a graceful fawn—may her breasts satisfy you always; may you be captivated by her love forever." This passage encourages husbands to find joy and satisfaction in their wives, promoting a lifelong commitment to marital faithfulness.

Prophetic Warnings

The prophets frequently used the metaphor of marriage to describe the relationship between God and His people, Israel. When Israel was unfaithful, it was likened to marital infidelity. For instance, in Jeremiah 3:20 , God laments, "But as a woman may betray her husband, so you have betrayed Me, O house of Israel," declares the LORD. This metaphor highlights the seriousness of unfaithfulness and the pain it causes, both in human relationships and in the divine-human relationship.

New Testament Teachings

In the New Testament, Jesus reaffirms the importance of marital fidelity. In Matthew 19:4-6 , He states, "Have you not read that from the beginning the Creator 'made them male and female,' and said, 'For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh'? So they are no longer two, but one flesh. Therefore what God has joined together, let man not separate." Jesus emphasizes the permanence and exclusivity of the marital bond, reinforcing the call to fidelity.

The Apostle Paul also addresses marital fidelity in his epistles. In Ephesians 5:25-28 , Paul instructs, "Husbands, love your wives, just as Christ loved the church and gave Himself up for her to sanctify her, cleansing her by the washing with water through the word, and to present her to Himself as a glorious church, without stain or wrinkle or any such blemish, but holy and blameless. In the same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself." This passage highlights the sacrificial love and commitment required in marriage, mirroring Christ's love for the church.

Consequences of Infidelity

The Bible also addresses the consequences of marital infidelity. In Proverbs 6:32-33 , it is written, "He who commits adultery lacks judgment; whoever does so destroys himself. Wounds and dishonor will befall him, and his reproach will never be wiped away." This passage warns of the personal and social repercussions of adultery, including shame and lasting damage to one's reputation.

Conclusion

The biblical narrative consistently upholds the seriousness of marital fidelity, portraying it as a reflection of God's covenantal love and faithfulness. Through various genres and teachings, the Scriptures call believers to honor and maintain the sanctity of the marital bond, recognizing it as a divine institution with profound spiritual significance.
