In the U.K. and the U.S., it is commonplace to find an appeal to biblical texts by both critics and advocates of meat-eating, albeit for different reasons. In particular, a specific range of pericopes repeatedly occur. I shall term the discourses surrounding these pericopes and their exegesis in this context “carno-theology”. Before the later nineteenth century, nonconformists mostly read these same pericopes in ways unrelated to the ethics of meat-eating. The transition from this nonconformist discourse to carno-theology occurred over the same period that meat production became industrialised, and more available to the general public, most of whom possessed at least a nominal Christian faith. Many Christians, both then and now, know, or at least suspect, that meat-eating is ethically compromised, yet continue the practice with relish. Carno-theology helps reduce the cognitive dissonance thus experienced, and reconfigures as biblical the addictive mechanisms which drive it. This chapter examines this shift in discourse in two respects: its use by Christian communities, especially by an “evangelicalism” which claims a nonconformist heritage, to justify a practice which might otherwise seem deeply problematic; and its secular use to oppose meat-eating by associating it with an “obviously” flawed religious ideology. The once alternative Christian discourse, now largely subjugated, provides a point of resistance from which to survey both these carno-theological narratives.
