Žižek and Milbank go head to head, in a forthcoming book from MIT Press:

In this corner, philosopher Slavoj Žižek, a militant atheist who represents the critical-materialist stance against religion’s illusions; in the other corner, “Radical Orthodox” theologian John Milbank, an influential and provocative thinker who argues that theology is the only foundation upon which knowledge, politics, and ethics can stand. In The Monstrosity of Christ, Žižek and Milbank go head to head for three rounds, employing an impressive arsenal of moves to advance their positions and press their respective advantages. By the closing bell, they have not only proven themselves worthy adversaries, they have shown that faith and reason are not simply and intractably opposed.
