I know you are saying such an example would not constitute a sin of any kind.
You are wrong. It is a sin but a venial one.
I agree with the Church and the position of Augustine and Aquinas.
I happen to disagree with your position, and I agree with the Church and the position of Origen and Chrysostom.
I thank you Thistle for postin that link to This Rock article, but that article seems to tear away from your CCC argument, it reads:
"I referred earlier to the difficulty of conceptualizing a perfect definition of lying that might reveal a solution to our dilemma. The magisterium of the Church has not endorsed any such definition, but it recently came very close to taking a small step in that direction. Over the past hundred years there has been a growing movement among moral theologians to tweak the definition of lying as follows: “To lie is to speak or act against the truth in order to lead into error someone who has the right to know the truth.” This very sentence, in fact, is taken from the initial edition of the Catechism of the Catholic Church (CCC 2483, 1994 edition).
When the Catechism was first published in French in 1994, and translated into other languages from the French, it contained the sentence quoted above, and so there was some speculation that the Holy See had finally decided to throw at least a modicum of magisterial weight behind this solution to our dilemma. This very precise definition, with its inclusion of the right to know, enables us to handle lying and falsehood in a manner very similar to the way we handle murder and killing. Through a person’s intention to use particular knowledge for an evil end, that person would presumably forfeit his right to know. Thus it would be morally acceptable to speak a falsehood to the murderous thugs. But we would no more call this “lying” than we would call an act of self-defense “murder.”
Alas, the matter is not so easily resolved. For, as it turns out, when the official Latin text of the Catechism was released in 1997 after a process of revision, the right to know was dropped. The operative sentence now reads simply: “To lie is to speak or act against the truth in order to lead someone into error.” Of course, the Catechism is intended as a basic compendium of Catholic doctrine, assembled with due ecclesiastical care, and not as a collection of definitive infallible pronouncements permanently settling every question on every topic it covers. In other words, the change in definition does not mean the original formulation was wrong. But it does mean that the editors of the Catechism were not prepared to endorse it in an official Catholic reference work. In the end, then, the current Catechism does not directly address our problem. "
So, we are back where we began and I also haven’t seen my argument addressed by anyone, which is a slightly different take, but Biblically based. Was it that bad that no one felt compelled to either agree or disagree with it?
