He begins:
Karl Barth was the greatest theologian since the Reformation, and his work is today a dead letter. This is an extraordinary irony. Barth aspired to free Christian theology from restrictive modern habits of mind but in the end preserved the most damaging assumptions of the ideas he sought to overcome. This does not mean he no longer deserves serious attention. Barth now demands exceptionally close attention, precisely because his failures can teach us how profound the challenges of modernity are for theology—and show us the limits of a distinctly modern solution to them.
