Biblical Answer

The biblical prohibition against adultery is a protective measure, the violation of which brings destruction. Fidelity in marriage promotes the well-being of all in the family: it preserves the integrity of the couple and the relationship. The Bible clearly prohibits divorce except on the ground of unchastity (adultery). Jesus teaches that divorce and remarriage are sinful (Matthew 5:31-32, Matthew 19:3-12). In Matthew 5:31-32, Jesus states that everyone who divorces his wife, except for the reason of unchastity, makes her commit adultery; and whoever marries a divorced woman commits adultery. This teaching emphasizes the seriousness of adultery as a ground for divorce.

The Bible does not explicitly state that adultery is the only ground for divorce. In fact, the account in Matthew 19 suggests that the dissolution of marriage can occur due to hardness of heart (sin) or permanent desertion. Some interpreters argue that if a spouse is sexually unfaithful, divorce is permissible. However, Paul conveys the main point of the Jesus tradition: divorce and remarriage are sinful. This suggests that while adultery may be a ground for divorce, it is not the only ground. The absence of a similar exception for other grounds, such as chronic addiction or desertion, in the biblical text may indicate that these are not considered legitimate grounds for divorce.

In conclusion, the Bible teaches that adultery is a serious violation of marriage, but it does not explicitly state that it is the only ground for divorce. While Jesus teaches that divorce and remarriage are sinful, the Bible does allow for divorce in certain circumstances, such as adultery or hardness of heart (sin). The interpretation of these passages is complex, and different Christian traditions may have varying views on the matter. However, it is clear that the Bible emphasizes the importance of fidelity in marriage and the seriousness of divorce as a violation of the marriage vow.
