The technical term for “lying to bring down a greater lie” is “lying”. The Catechism does not say you may lie to bring down a greater lie. It says that “by its very nature” lying is to be condemned. It gets that from Jesus, who says that the lie is the native tongue of the devil. It gets it from Augustine, who specifically wrote an entire treatise against lying when some of his flock said it was necessary to lie in order to bring down a greater lie. It gets it from Aquinas who answers the question, “Is lying always sinful?” in the affirmative. And it gets it from the eighth commandment, which forbids the grave sin of bearing false witness against your neighbor since you might, as O’Keefe shamefully did, wind up ruining an innocent person with your lies and then get sued for $100,000 dollars and lose because you are a liar who ruined an innocent person.
Hopefully O’Keefe has learned from this bitter experience and will stop leading the faithful astray with this consequentialist mendacity. And hopefully foolish Christians will not persuade him he is a noble martyr who did nothing wrong and urge him to continue fighting sin with sin. Also, spare me any euphemisms or attempts to claim that he “wasn’t really lying”. When O’Keefe himself calls it lying, it’s lying. Lying is–always–sinful, though not always, or even usually, mortally sinful. Christians should stop defending sin and start opposing it, especially if they are going to brag about being “Faithful Conservative Catholics”. One of the most fundamental precepts of Catholic morality is “You shall not do evil that good may come of it.” Learn it. Love it. Live it. You fight lies with truth, not more lies. That was Augustine’s common sense insight. The weapons of our warfare are not worldly weapons, but the weapons of the Spirit.
