THE QUESTION: Is it moral for a Christian to work as a spy, and in the process deceive the enemy or employ illicit sex to obtain essential information?

THE RELIGION GUY’S ANSWER: Let's explore that fascinating ethical topic, raised by a recent lead article in Providence, a young “journal of Christianity & American foreign policy.” See this link. The journal’s cover illustration, from Alfred Hitchcock’s classic 1946 movie “Notorious,” showed a U.S. agent (Cary Grant) who seduces and recruits a woman (Ingrid Berman) to exploit her sexuality and spy on Nazis in Brazil.

Fiction aside, consider true-to-life British agent Amy Elizabeth (Betty) Thorpe, who operated during World War Two under the code name Cynthia. She seduced the press attache at the embassy of France’s pro-Nazi Vichy regime and enlisted him in traitorous deceit to feed her secret information. (They later married.) Thorpe had no apologies. She was told her efforts saved thousands of British and American lives and explained, “Wars are not won by respectable methods.”

Providence is neo-conservative in outlook and takes inspiration from liberal Protestant theologian Reinhold Niebuhr (1892-1971), who forsook youthful pacifism to espouse “Christian realism” and endorse a necessary “just war” as moral. The journal likewise believes Christians should support use of military force when it’s ethical in terms of the who, the why, and the how.

If we assume soldiering and killing in combat are moral to defend the innocent and one’s country, it makes sense that spying on the enemy for a good cause is an acceptable vocation for a Christian. But if so, what tactics should spies employ, or shun?

Those matters were addressed in Providence by Darrell Cole, an ethics professor at Drew University, whose pertinent  book “Just War and the Ethics of Espionage” (Routledge) has just been issued in paperback. To cut to the chase -- or the chaste -- Cole accepts lying to help a just cause but flatly rejects sexual seduction. Let’s unpack this.

First, is it always evil to bear false witness?
