I found this comment as an end note in John Caputo’s The Weakness of God: A Theology of Event:

Radical Orthodoxy is a movement that turns the quaint and (self-)comforting idea that everything is either a Christian metaphysics of participation (that is, Radical Orthodoxy) or nihilism, by which they seem to mean variants of their version of Nietzsche or Derrida, which for them means that human existence is awash in an irrational flux. So Radical Orthodoxy, which gives us a choice between being Cambridge Thomists or nihilists, needs to expan its horizons. (310)
