Is it really true that Pope Benedict’s approval of condoms to prevent the transmission of HIV/AIDS is backed by very traditional teaching of Augustine and Aquinas? James Heffernan, writing at Huffington Post, seems to think so. First, he refers to Aquinas on the validity of self-defence, and asks, does this imply that condoms are justifiable in AIDS prevention, as self-defence against infection?
In the 13th-century Summa Theologica, perhaps the greatest of all treatises on Roman Catholic doctrine, Saint Thomas Aquinas says that one may lawfully kill an assailant in self-defense. In such cases, says Aquinas, one’s action has a double effect: killing another and saving one’s own life. “Therefore, this act” he says, “since one’s intention is to save one’s own life, is not unlawful, seeing that it is natural to everything to keep itself in being as far as possible” (ST II-II, Qu. 64, Art 7).
If Aquinas says it is “NOT unlawful” to kill in self-defense, could he possibly say it IS unlawful to use a condom in self-defense, as a means of protecting oneself against fatal infection, or one’s partner from such infection?
