Gabriel Vahanian rose to international attention as part of the "death of God" movement in American theology in the 1960s. Yet to see him as primarily a 1960s "death of God" theologian is to severely underestimate the scope and depth of his theology, a theology that can perhaps be best described as a radical theo-poetics of the secular. In all his theological writing, Vahanian was consistently aware of his context and situation as theologian of the secular, post-Christian age. This chapter demonstrates how Vahanian was always concerned with the question of what does it mean to be, to decide, or to attempt to be Christian after the death of God—after Christendom, after the culture of Christianity?
