"How is one to explain that neither Hitler nor Himmler was ever excommunicated by the church? That Pius XII never thought it necessary, not to say indispensable, to condemn Auschwitz and Treblinka? That among the S.S. a large proportion were believers who remained faithful to their Christian ties to the end? That there were killers who went to confession between massacres? And that they all came from Christian families and had received a Christian education?"
