D. A. Carson, The Gagging of God: Christianity Confronts Pluralism (Grand Rapids: Zondervan, 1996), 470 (emphasis in original):

Churches that are faithful to the apostolic gospel are sometimes also the ones that are loyal to a culture becoming increasingly passé. In such a situation cultural conservatism can easily be mistaken for theological conservatism, for theological orthodoxy. In an age of confusing empirical pluralism and frankly frightening philosophical pluralism, in an age that seems to be stealing from us the Judeo-Christian worldview that prevailed for so long, it is easy to suppose that retrenchment and conservative responses on every conceivable axis are the only responsible courses for those who want to remain faithful to the gospel.

In various ways I have tried to show in this volume that such a course is neither wise nor prophetic. Sometimes it is not even faithful. The church may slip back into a defensive, conservative modernism that is fundamentally ill-equipped to address postmodernism.
