If, as Crockett (Energy And Change. A New Materialist Cosmotheology. New York: Columbia University Press, 2022) argues, energy and change is a theological issue, then I argue it is also a political theology issue. Drawing on the short-circuit reading strategy of Slavoj Zizek, this chapter reads Carl Schmitt and Jacob Taubes ‘as if’ they were talking about questions of energy and change. The chapter proceeds from the letter exchange of Schmitt and Taubes as recorded in To Carl Schmitt (2013), introducing the categories of the sovereign, the katechon, and the anti-Christ, that arise from this discussion of Schmitt and Taubes. In Schmitt’s political theology, the sovereign is the one who makes the exception; while in the letters to Schmitt, Taubes brings up the notion of the katechon, the restrainer of the anti-Christ and of the apocalypse that follows. A political theology of energy and change recognizes that contemporary discussions of energy use implicit and explicit language of apocalypse, sovereignty, decision, and exception—in short, the terms of political theology. But who or what is the energy sovereign? What constitutes a political theology of energy—especially a new materialist political theology of energy? Such questions are at the heart of a political theology of energy.
