Recently, a somewhat opaque term found its way onto the front page of The Immanent Frame in the title of Daromir Rudnyckyj’s piece on “post-secular development.” This term, “postsecular,” also came up a few months ago in Nathan Schneider’s interview with Simon During as well as a string of other entries in this blog over the past few years. A group of contributors to The Immanent Frame, including its founding editor Jonathan VanAntwerpen and editor-at-large David Kyuman Kim, are even involved in editing a volume called The Post-Secular in Question. Apparently the term is quickly becoming a keyword for scholars of religion and public life. So, what is it all about?
