<p>This article presents a reinterpretation of Jean-Luc Marion’s concept of saturated phenomena in a postsecular spirit. The basis of the reinterpretation incorporates references to (1) a critique of the definition of the concept of religion on the basis of the opposition between the sacred and the profane and (2) the results of debates on the theory of secularization in the second half of the 20th century. Postsecular optics are introduced, after which the key concepts from Marion’s philosophy, such as idol, icon, gift and givenness, are discussed in the context of the theory of saturated phenomena. How these concepts can be understood and used in terms of describing postsecular, contemporary culture and spirituality is explained. Ultimately, saturated phenomena are presented as a concept useful for philosophically capturing states of consciousness that can be called profane illuminations, which allude to traditional theology and materialistically oriented humanities in need of a subtler language of description: a so-called theology of worldliness.</p>
