 Zuccotti (2000) describes the language used in dealing with the "Jewish problem" as "ominous in retrospect".During the first half of 1937, the journal continued to run denunciations against the Jews but in the aftermath of the encyclical Mit brennender Sorge Father Mario Barbera (who had authored some of these strident attacks) for a brief period during the summer of 1937 changed course and, whilst repeating familiar accusations, called on Catholics to remove from their hearts any form of anti-Semitism and anything that might offend or humiliate Jews.He would return to the older style of warnings a few months later.
