Both the FBI agent and his FBI girlfriend lawyer are married. They were having an affair with each other while married. In other words, both were committing adultery. And no one in the FBI, Washington political establishment or mainstream media seems to think anything of it or even care.
There was a time decades ago when adultery was considered shameful and disqualified one from high office. In the United States, laws vary from state to state. Up until the mid 20th century most U.S. states (especially Southern and Northeastern states) had laws against fornication, adultery or cohabitation. These laws were gradually abolished or struck down by courts as unconstitutional. As of 2017, adultery remains a criminal offense in 21 states, but prosecutions are rare. In the U.S. military, adultery is still a criminal offense under the Uniform Code of Military Justice (UCMJ).
Times have changed. As the culture morally collapsed, adultery alarmingly became no longer shameful. It waxed blase' to the point where some consider it as a mark of maturity and even somewhat of a badge of honor. In fact though, the cultural apathetic attitude towards adultery is the defining sign of moral rot.
If someone violates their most sacred vow (marriage), why would we consider them trustworthy in anything else? Turning a blind eye to adultery in an organization entrusted with the most sensitive secrets (i.e., the FBI), is foolhardy. It opens Pandora's box, signaling clear acceptance of the worst kind of immoral behavior, and ultimately opens the floodgates to the moral rot and corruption that is now so disturbingly prevalent in our government.
Scripture is clear that sexual sin is in a category of its own, and adultery is the worst of sexual sins because if violates the most sacred and intimate of vows. As I wrote here in March of 2017, I believe the Roman Catholic and Orthodox perspective is correct on marriage and I agree with CS Lewis that marriage is indeed a sacrament, signifying the relationship between Christ and His church. Breaking that most intimate of relationships is serious rebellion.
The cultural acceptance of adultery underlies all that is wrong. It is the foundation stone of moral corruption and a screeching warning klaxon that we have gone off the rails and are rapidly headed for catastrophic derailment.
