Biblical Definition of Adultery

In biblical terms, adultery is defined as a sexual relationship between a married person and someone who is not their spouse, constituting a violation of the marital covenant. This definition is derived from various scriptural references, where adultery is condemned as a grievous sin, implicating both moral and spiritual dimensions.
The marital covenant, as depicted in the Bible, is not merely a legal contract but a sacred bond ordained by God. Adultery, consequently, disrupts this divinely instituted bond, leading to significant ethical and relational ramifications.
The gravity of adultery in biblical texts underscores the importance of fidelity, purity, and respect within the sanctity of marriage. Hence, adultery is seen as a profound breach of trust and divine commandment.
Adultery in the Ten Commandments

The profound significance of adultery as a breach of marital fidelity is further emphasized within the Ten Commandments, where it is explicitly prohibited as one of the fundamental moral imperatives.
The Seventh Commandment, stated in Exodus 20:14, succinctly declares, 'You shall not commit adultery.' This injunction underscores the sanctity of marriage and the importance of trust and faithfulness between spouses.
By including adultery among prohibitions such as murder and theft, the Decalogue elevates marital fidelity to a foundational ethical principle.
The commandment serves not merely as a rule but as a divine mandate reflecting the covenantal relationship between God and humanity, which mirrors the exclusive and committed nature of marriage.
Consequently, its presence in the Ten Commandments emphasizes its critical role in maintaining societal and spiritual order.
Old Testament Views on Adultery

Examining the Old Scriptures reveals a multifaceted perspective on adultery, intertwining legal, moral, and theological dimensions to underscore its gravity.
The Old Scriptures delineate adultery as a severe transgression with far-reaching consequences, illustrated through various texts:
- Legal Consequences: Leviticus 20:10 mandates the death penalty for both participants, highlighting its severity in ancient Israelite law.
- Moral Implications: Proverbs 6:32-33 emphasizes the foolishness and self-destructive nature of adultery, damaging one's reputation.
- Theological Significance: Adultery is equated with idolatry in Jeremiah 3:8-9, indicating a breach of covenant with God.
- Narrative Examples: The story of David and Bathsheba (2 Samuel 11) serves as a cautionary tale of moral failure and divine judgment.
These elements collectively illustrate the profound seriousness of adultery in the Old Scriptures.
New Testament Teachings on Adultery

A notable shift in the approach to adultery is evident in the New Covenant, emphasizing not only the act but also the intent and condition of the heart.
Jesus, in the Sermon on the Mount, extends the definition of adultery beyond physical infidelity to include lustful thoughts (Matthew 5:27-28). This broader interpretation underscores a deeper moral introspection, focusing on inner purity.
The Apostle Paul reiterates this stance, admonishing believers to flee from sexual immorality, reflecting a holistic view of sanctity in body and spirit (1 Corinthians 6:18-20).
Moral and Spiritual Consequences

This expanded understanding of adultery's nature invites an examination of its moral and spiritual ramifications as delineated in biblical texts.
The Bible presents several consequences for adultery, reflecting its profound impact on both the individual and the community. These include:
- Moral Degradation: Adultery is seen as a breach of ethical conduct, contributing to the erosion of personal integrity.
- Spiritual Alienation: Engaging in adultery distances individuals from their relationship with God, disrupting spiritual communion.
- Social Disruption: It undermines the sanctity of marriage, leading to familial instability and societal disarray.
- Divine Judgment: Scripture often warns that adulterers face God's disfavor, emphasizing the gravity of such sin.
Understanding these consequences underscores the biblical emphasis on fidelity and holiness.
Conclusion
In summation, the Bible unequivocally condemns adultery, underscoring its moral and spiritual ramifications through both Old and New Scriptures teachings.
Adultery is depicted not only as a breach of marital fidelity but also as a violation of divine commandments, thereby inviting severe consequences.
For instance, in the story of David and Bathsheba, David's act of adultery led to a series of tragic events, including familial strife and divine punishment, illustrating the profound implications of such transgressions.
