It would be futile to deny that the Nazis built a vast mass of evil on a vast mass of prejudice. It would be equally futile to deny that strong prejudices against the Jews existed among Christians during the centuries before the Shoah. Since, moreover, the childhood of the European nations was passed under the tutelage of the clergy, we should not be surprised that these prejudices were, in part, ecclesiastically inculcated.
