This article recovers Martin Buber’s important but neglected critiqueof Carl Schmitt’s political theology. Because Buber is knownprimarily as an ethicist and scholar of Judaism, his attack onSchmitt has been largely overlooked. Yet as I reveal through a closereading of his Biblical commentaries, a concern about the dangers ofpolitical theology threads through decades of his work. Divinesovereignty, Buber argues, is absolute and inimitable; no humanruler can claim the legitimate power reserved to God. Buber’sresponse is to uncover what he sees as Judaism’s earliest politicaltheory: a “theopolitics,” where human beings, mutually subject todivine kingship, practice non-domination. But Buber, I show, did notseek to directly revive this religious vision. Instead, he sought toincorporate the spirit of theopolitics, as embodied by Israel’sprophets, into modern society. The result is a new and significantperspective on liberal democracy and political theology.
