If it’s magic to believe that merely saying something can make it so, then J. L. Austin’s account of the so-called ‘performative utterance’ is an account of a magical belief. For that, though not quite true without qualification, is what Austin maintains is the nature of a performative utterance. On the other hand Austin is not the first person one would think of as a believer in magic. And his undoubted credentials for unsuperstitiousness have given authority to the notion of the performative utterance which some theologians have thought to exploit for their own purposes. And some sociologists too. For these reasons respectively.

Theologians do not have a reputation so clear of superstition as Austin has. In particular, Roman Catholic theologians don’t and even more, among Roman Catholic theologians, those who concern themselves with rituals and sacraments don’t. And some of these have wanted to go along with the likes of Aquinas and the Tridentine formulae about sacraments and wish to legitimate propositions, such as that of Aquinas, that a sacrament is a sign which “effects what it signifies”. As this appears to mean that merely saying a thing, such as “This is my body” uttered over what is prima facie bread, or “I baptise you ...” said while pouring what is on any account water, is to make what it says so, and as such theologians are sensitive to the charge that this is mere magic-making, there is an evident temptation to exploit Austin on performatives in the prospect of de-mystifying such claims.
