This article is devoted to the transformation of the phenomenological method in contemporary post-metaphysical theology. It traces the path from Husserl’s transcendental reduction through Heidegger’s ontological difference and Marion’s donological reduction to the radical strategies of thinking about the divine in the works of J.-L. Marion, J.D. Caputo, R. Kearney, and J.P. Manoussakis. We analyze their approaches to the problem of reduction and demonstrate how the shared legacy of Husserl and Heidegger leads these thinkers to different strategies for thinking about the divine. Caputo develops a “hauntological reduction” that transforms the existence of God into a spectral event and affirms a “weak theology” of pure expectation. Kearney and Manoussakis, in contrast, propose a prosopic (eschatological) reduction that returns philosophy to the face of the Other as the site of a concrete encounter with transcendence. It is shown that in these projects, reduction ceases to be a procedure of “subtracting” the everyday world for the sake of access to a transcendental subject or the fundamental structures of being, transforming into a method of deep attention to concrete, carnal, often marginal phenomena in which traces of the Other are revealed. We argue that the transformations of phenomenological reduction in contemporary religious thought signifies the search for a non-metaphysical language for describing religious experience, as well as to the return to philosophy of the fullness of its carnal, aesthetic, ethical, and eschatological dimensions. The article demonstrates that the discussion of method in post-metaphysical theology determines our understanding of divine being, our responsibility to the Other, and the very task of thinking “after God”.
