"Good news" after Auschwitz?

"Mary argue that in a post-Holocaust world Christians must address their own culpability in the destruction of Europe's Jewry. If post-Holocaust Christians only lament Christianity's sin, which has been catastrophically destructive in its anti-Jewish manifestations, the traditions will ultimately be left with little to say and no credibility. Post-Holocaust Christians must emphasize positive differences that Christianity can make."--Jacket.
