The concept of katechon, in the way it is generally invoked today, only exacerbates already existing political and ideological divisions, pitting ‘conservatism’ against ‘progressivism’, or ‘multipolarity’ against ‘globalism’ and ‘hegemony’. With Carl Schmitt as an unlikely ally, this article argues that the katechon might instead offer an alternative — non-liberal and non-revolutionary — universalist political project, thus showing the way out of these oppositions. Contrary to dominant interpretations, Schmittian notion of the katechon is not a legitimation of either sovereign state power or international plurality. Instead, it embodies an underappreciated universalist strand in Schmitt’s thought, which stands in tension with the confrontational and pluralist logic of his concept of the political or the idea of the Grossraum order. For Schmitt, the katechon implies an essentially non-sovereign form of power, which both maintains and renews an existing social order to ensure the continuation of history understood as the realm of ‘infinite singularity’. In modern times, this primarily involves guarding against the threat of technocratic globalization that portends either a collapse of humanity into nature-like regularities or its technological suicide. However, instead of opting for international plurality as a solution, in an often-neglected Spanish version of an essay “The Unity of the World” Schmitt directly links the katechontic theology of history to a specific kind of ‘true’ political universalism, opposed both to the ‘false’ universalism of techno-economic liberalism, and to antagonistic pluralism. Although he does not explicitly elaborate the details of this ‘true’ universalism, his work hints at the diarchy of spiritual and temporal powers as a crucial element of katechontic world unity.
