In his 1923 work, Roman Catholicism and Political Form, Carl Schmitt claims that representation is a complexio oppositorum (a unity of opposites) and incarnates a hierarchical form of political authority, which is alternative to liberalism. This article shows that Carl Schmitt’s interpretation of the political theology of representation is based on a misreading. Schmitt selectively overlooks some meanings of the theology of repraesentatio to build his decisionistic political agenda. An investigation of the original conceptual meanings of representation in Tertullian, the first Christian author who theorized representation and established many of its subsequent theological meanings, shows a different picture. At its inception, representation already included mechanisms of plurality and participation, which anticipated, and perhaps motivated, the absorption of the representation vocabulary within democratic discourse and practice. Political theology is a valuable field of inquiry to prove the claim that there is no participation without the logic of representation.
