This article presents the work of Czech theologian and priest Tomáš Halík as a theology for the post-secular. The first section outlines three general post-secular themes woven throughout his corpus: the blessedness of spiritual seeking, a receptivity to the critical insights of atheism, and the affirmation of doubt and uncertainty as an integral feature of Christian faith. The second section then demonstrates what is distinctive about Halík’s contribution: his engagement with themes of both plurality and uncertainty in a single theological schema. I argue this is an apt response to the post-secular dynamics of the nova effect—as outlined by Charles Taylor and others—that is otherwise lacking in the literature to date.
