Ernst Troeltsch is known to church historians largely for his classic threefold distinction of church, sect, and mysticism. In The Social Teachings of the Christian Churches, Troeltsch describes the church as an institution enmeshed with society and making accommodations to the world's imperfections; the sects, driven by a quest for purity, refuse to make accommodations or compromises, while the mystics stand aside from this conflict and concern themselves with “a purely personal and inward experience” in which “the isolated individual, and psychological abstraction and analysis become everything.” Troeltsch sees mysticism not as a phenomenon naturally at home within the church but rather as one that leads away from the establishment, and it is perhaps this perception in particular that gives his work lasting relevance. The assumption that mysticism veers naturally in an antiecclesial direction, and that its more orthodox manifestations are anomalies requiring explanation, remains very much alive in the literature. Indeed, from the perspective of cultural materialism, it is the political, antiecclesial, subversive bite of mysticism that is its most interesting feature. On this point liberal Protestantism and postmodernism have come together, theology and cultural studies have embraced. Troeltsch's schema thus retains relevance well beyond the sphere of historiography.
