Definition and Context:
Marriage violations in the biblical context refer to actions or behaviors that transgress the divine laws and principles established for the sanctity and integrity of marriage. These violations are addressed throughout the Scriptures, highlighting the importance of maintaining purity, fidelity, and respect within the marital covenant.

Biblical References:

1. Adultery:
Adultery is one of the most frequently mentioned marriage violations in the Bible. It is defined as a married person engaging in sexual relations with someone other than their spouse. The commandment against adultery is clear: "You shall not commit adultery" (Exodus 20:14). The gravity of this sin is further emphasized in Leviticus 20:10, which prescribes severe consequences for those who commit adultery.

2. Fornication and Sexual Immorality:
Fornication, often used interchangeably with sexual immorality, encompasses a range of illicit sexual behaviors outside the bounds of marriage. The New Testament frequently warns against such practices. In 1 Corinthians 6:18, believers are admonished to "Flee from sexual immorality. Every other sin a man can commit is outside his body, but he who sins sexually sins against his own body" .

3. Divorce and Remarriage:
The issue of divorce is addressed with caution in the Scriptures. Jesus speaks to the sanctity of marriage in Matthew 19:6, stating, "So they are no longer two, but one flesh. Therefore what God has joined together, let man not separate" . While allowances for divorce are mentioned, such as in cases of sexual immorality (Matthew 19:9), the overall biblical narrative upholds marriage as a lifelong covenant.

4. Polygamy:
Although instances of polygamy are recorded in the Old Testament, the biblical ideal for marriage is monogamy. Genesis 2:24 sets the foundational principle: "For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh" . The New Testament reinforces this standard, particularly in the qualifications for church leaders, who are to be "the husband of but one wife" (1 Timothy 3:2).

5. Incest:
Incest, or sexual relations between close relatives, is explicitly prohibited in the Scriptures. Leviticus 18 outlines various forbidden relationships, emphasizing the need to maintain familial purity and respect. Verse 6 states, "None of you shall approach any close relative to have sexual relations. I am the LORD" .

6. Homosexuality:
The Bible addresses homosexual acts as contrary to the natural order established by God. Leviticus 18:22 states, "You shall not lie with a man as with a woman; it is an abomination" . The New Testament reaffirms this stance in passages such as Romans 1:26-27, which describes such acts as contrary to nature.

Theological Implications:
Marriage violations are not merely breaches of social norms but are seen as transgressions against God's divine order. The biblical narrative consistently upholds marriage as a sacred institution designed to reflect the relationship between Christ and the Church (Ephesians 5:31-32). Violations of this covenant are viewed as serious offenses that disrupt the intended harmony and sanctity of the marital bond.

Pastoral Considerations:
In addressing marriage violations, pastoral care often involves guiding individuals towards repentance, reconciliation, and restoration. The church is called to uphold the biblical standards of marriage while extending grace and support to those seeking to align their lives with God's will.
