re: Does sleeping with a married woman make you a bad person (If you are not married).

The dictionary defines “adultery” as “voluntary sexual intercourse between a married person and a person who is not his or her spouse.” The Bible would concur with this definition. In Leviticus 18:20, God told Moses, “Do not have sexual relations with your neighbor’s wife and defile yourself with her,” and in Deuteronomy 22:22, we find a similar definition: “If a man is found sleeping with another man’s wife, both the man who slept with her and the woman must die.” It is clear from these definitions that adultery refers to a consensual sexual union. What is not explicitly clear is whether or not both partners in this illicit sexual union are married. The biblical commands prohibit a man from taking another man’s wife, but do not indicate whether or not the man is also married. Be that as it may, it is safe to say that if a person who is married willingly seeks a sexual encounter with another person, whether or not that person is also married, both people are guilty of committing adultery.
