How should we diagnose the reasons for the present crisis of confidence in secularism? Is this a result of our failure to offer a sufficiently robust civil religion as a necessary supplement to a liberal order that is excessively individualist and rationalist? Or of the intellectual incoherence of secularism, given the permeability of the boundary between the religious and the political? Does it still appear possible and desirable to defend a separation between religion and politics, when so many indicators are firmly against this, including the rise of Christian nationalism in such places as the contemporary United States? Or is secular liberalism really just another “political theology,” as Carl Schmitt contended?
