In 1980 a book appeared which caused a considerable stir across the globe: Michelle Remembers by Lawrence Pazder and Michelle Smith. This book helped set in train what was later referred to by scholars as the “Satanic Panic” or the “Satanism Scare”. While the book became infamous, little analysis by scholars has been given to the authors’ Roman Catholicism, or more importantly to the wider way in which Catholicism contributed to this moral panic. While the influence of Christians more generally has been noted, sparse attention has been given to the ways in which a variety of distinctly Catholic vernacular beliefs and subcultures fed and spread this panic. This article seeks to map some of the contours of the specifically Catholic contribution to the wider Satanic Panic mythology, contextualising this against the backdrop of a wider ecclesial shift in a conservative direction during this period and the Church’s longer history of demonology. The paper concludes by suggesting that this Satanic Panic mythology persists and forms one important reservoir of ideas drawn on in contemporary demonology.
