Biblical Answer

To answer the question of whether adultery is the only ground for divorce, we must first consider the biblical prohibitions against divorce. In both Matthew passages on the subject (Mt 5:31-32; 19:3-9), Jesus forbids divorce except on the ground of unchastity (rsv). This means that divorce is not permitted except in cases where there has been sexual infidelity or adultery. 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 promotes the well-being of the children.

The biblical account of divorce is also instructive. In Old Testament times, when a wife was a known adulteress, divorce was almost mandatory. Reconciliation would have been immensely shameful for the husband and his family, so divorce was seen as a necessary step to protect the family's reputation. However, this does not mean that other grounds for divorce are not permitted. Some argue that permissible grounds to divorce must include even more because Moses and Jesus both used terms that usually cover more than physical adultery alone. In fact, some scholars suggest that sexual infidelity and abandonment are the unexceptional grounds for divorce, beyond which no one should go.

In conclusion, while the biblical prohibitions against divorce are clear, the debate continues over whether other grounds are included as well. Some argue that permissible grounds to divorce must include even more, while others conclude that adultery is the only ground for divorce. Ultimately, the decision to divorce should be made with caution and careful consideration, taking into account the biblical teachings on marriage and divorce. As Jesus said, "Everyone who divorces his wife, except for the reason of unchastity, makes her commit adultery; and whoever marries a divorced woman commits adultery" (Matthew 5:31-32). This passage makes it clear that divorce should not be taken lightly and should only be considered in cases where there has been sexual infidelity or adultery.
