If someone is unfaithful to their spouse, which commandment is violated?

• A. The Fifth Commandment
• B. The Sixth Commandment
• C. The Seventh Commandment
• D. The Ninth Commandment

Answer: (B)

Fidelity in marriage is what this question is about. Adultery means being unfaithful to a spouse, which is exactly what the commandment about faithfulness in marriage prohibits. In this set, the instruction that addresses not being unfaithful to a husband or wife is the one described, so selecting that idea lines up with the commandment’s intent. Remember that traditions number commandments differently, but the point remains: faithfulness in marriage is required. The other options point to different commandments—honoring parents, not killing, not stealing, or not lying—so they don’t address marital fidelity.
