This collection of essays considers the return of the religious in contemporary literary studies. In the twenty-first century it is now possible to detect a new sacred turn in thought and writing. For some writers, this post-secular identity plays itself out in both a recuperation of religious traditions (Catholicism, Puritanism, Judaism) and a re-invention of the religious imaginary (apophaticism, messianism, apocalypticism, fundamentalism). In literary studies, the implications of the post-secular are revitalizing critical engagement with canonical works and fuelling the reclaiming of neglected writings as questions of the construction of spiritual identities come once again to the fore.
