Whenever I defend St Thomas’s teaching that lying is always wrong people give me the “Nazis…Jew-in-the-basement-objection.” Nollie Tan Boom faced with that actual situation didn’t see it as warranting lies, but this doesn’t persuade the objectors one bit. The argument from the proper end of speech seems to them abstract and irrelevant. Just recently I had two hour long argument with someone which got us absolutely no-where. Then I listened to John Francis Nieto’s defense of St Thomas’s position in this lecture, and was absolutely moved to tears by its beauty and persuasive power. I urge you, gentle reader: listen to that lecture; it is Moral Theology as it should be. The power of Nieto’s argument comes from the way in which he shows how St Thomas’s teaching on lying is integrated into his whole theology of the Christian life. Janet Smith recently criticized St Thomas’s teaching on lying as being based on a pre-lapsarian view of the nature of signification, but what Nieto shows is that, while St Thomas’s view is perfectly intelligible at the level of the proper principles of natural action, it can be understood much more fully in the light of the Incarnate Word, who is Truth itself. It’s not a pre-lapsarian view; it’s a fullness of time view.
