Jean-Luc Marion has recently established himself as one of the most important and theologically fertile thinkers within the phenomenological tradition. With his study of ‘the gift’ and ‘the saturated phenomenon’, Marion presents a challenge to theology to rethink revelation in its surprising givenness, as exceeding the boundaries often set up in advance by metaphysics and a priori anthropological foundations. This paper examines Marion's mature thought, particularly within the perspective of Christology. The paper argues that Marion's phenomenological style of reflection, as adapted to theology, is deeply contemplative and markedly Johannine in sensibility. As a strategy for theology, the phenomenological style gives to it important incentives and skills for reading off God's self-revelation in Christ in its surprising and counter-intuitive beauty. Marion's challenge/gift to theology is, however, in need of a balancing emphasis, one that appears too infrequently in his work: the ethical-prophetic dimension of the Christ event. In view of keeping both the mystical and prophetic poles of theology closely linked, the paper argues that just as beauty is a key category for saturated phenomena, so too is the reality of suffering and evil. However, whereas beauty invites a humble receptivity to and contemplative enjoyment of the gift, the inscrutable reality of suffering and evil, which so often exceeds comprehension, touches off a critical and practical response. In broadening the study of saturated phenomena to include the refractory character of experience, especially that which threatens humanity, Marion's valuable contributions to theology require a complementary emphasis from those narrative-practical Christologies that highlight the prophetic aspects of the tradition.
