23 The message itself betrays a consciousness of its own weakness and futility; and, hastening to save its argument, it adds three other reasons. The first reason is that the heads of Catholic Action were almost to a man members or heads of the Popular Party, which was one of the strongest opponents of Fascismo. This accusation has been launched many times against Catholic Action, but always in a general way and without specifying any names. Whenever We have asked for precise data and for names, it has been in vain. Only a short time before police measures were taken against Catholic Action, and in evident preparation for them, the hostile press, having no less evidently, access to police reports, had published a series of alleged facts and names which are the pretended revelations referred to in the beginning of the message. These the Osservatore Romano duly denied and corrected, instead of "confirming" them, as the message asserts, in an attempt to mystify and deceive the public.
