What was true of an ancient community of Christian believers struggling with a powerful and appealing philosophy is also true for Christians in a postmodern context. Arguments that deconstruct the regimes of truth at work in the late modern culture of global capitalism are indispensable. So also is a deeper understanding of the counterideological force of the biblical tradition. But such arguments are no guarantee that the biblical metanarrative will not be co-opted for ideological purposes of violent exclusion, nor do arguments prove the truth of the gospel. Only the nonideological, embracing, forgiving and shalom-filled life of a dynamic Christian community formed by the story of Jesus will prove the gospel to be true and render the idolatrous alternatives fundamentally implausible.
