This article considers imperial Roman and German forms of liberal elite consensus on “proper religious diversity” to set the stage for an examination of the contemporary form of liberal consensus discernible in a recent public talk given by Charles Taylor and Rowan Williams. In each case, attention is drawn to the ways in which “proper religious diversity” is defined to serve ideological and theological agendas. Romanitas, Germanentum, and the Taylor–Williams consensus are cannibalistic theological systems: each uses a public stance of (...) reasonable openmindedness regarding “proper religious diversity” to build and police a theological position that arrogates the perceived value of selected “religious” traditions by re-making them in its own image. Imperial Romanitas and Germanentum served in this way to absorb a diversity of traditions deemed palatable and digestible into overarching theological visions which were convenient to those in power. When Taylor and Williams use the platform of Religious Studies to promote the modern liberal view of “diversity in religion” as a source of pro-social order, their efforts serve a similar crypto-theological and imperialist project.
