Biblical Answer

The term "sexual immorality" in Matthew 19 refers to a broader concept that encompasses more than just literal sexual activity outside of marriage. In the context of the passage, Jesus is addressing the question of divorce and remarriage, and he quotes the Old Testament prohibition against marrying a divorced woman (Deuteronomy 24:4). The Greek term "porneia" ( pornos) is used to describe the sexual immorality that would make a marriage invalid. This term is related to the concept of idolatry and unfaithfulness to God, as seen in the Old Testament. In the New Testament, "porneia" is used to describe a range of immoral activity, including pre-marital sex, incest, and post-marital immorality.

In the New Testament, the term "porneia" is used in a broader sense to describe any form of sexual activity outside of marriage. This includes homosexual activity, as seen in 1 Corinthians 6:9-10, where it is listed alongside other forms of immorality. The passage in 1 Corinthians emphasizes that such activities are not only sinful but also characteristic of those who do not know God. The term "porneia" is also used in Revelation 14:8 to describe the "wine of the passion of her sexual immorality," which is a metaphor for the idolatrous and immoral behavior of Babylon. In this context, "porneia" is not just limited to literal sex but includes a range of immoral activity.

The Bible teaches that sexual immorality is a serious sin that requires repentance, forsaking, and forgiveness. In Matthew 19, Jesus teaches that remarriage after divorce is not permissible if the divorce was due to the husband's sexual immorality. This prohibition is not just limited to literal sexual activity but also includes any form of immorality that would make a marriage invalid. The Bible emphasizes that sexual fidelity before marriage is presumed, and any form of sexual activity outside of marriage is considered illicit. This includes homosexual activity, which is listed alongside other forms of immorality in the New Testament. Ultimately, the Bible teaches that sexual immorality is a sin that must be repented of and forgiven through faith in Jesus Christ.
