What does the Seventh Commandment forbid?

The Seventh Commandment, found in Exodus 20:14, specifically forbids adultery, which refers to marital infidelity. However, it also extends to all forms of unchaste actions or sexual immorality. This commandment emphasizes the importance of fidelity within marriage and promotes the sanctity of the marital relationship. By forbidding both adultery and other unchaste behaviors, it establishes a framework for sexual ethics that upholds commitment, loyalty, and respect between spouses.

In the context of the other options, while dishonesty in relationships, engaging in arguments, and seeking pleasure outside of marriage may be problematic behaviors, they do not encapsulate the specific focus of the Seventh Commandment, which is primarily about sexual conduct and fidelity. The commandment's broader application aims to protect the integrity of marriage and the family unit, making the correct answer comprehensive in its scope of moral prohibition.
