6 Referring now to certain notorious facts concerning which We have already raised Our voice in solemn protest and which even the daily press recorded at great length, there is no need to take up much space in telling you of certain deplorable events which occurred even in the very recent past with reference to Our Apostolic Delegates to Mexico. Without the slightest regard for justice, for solemn promises given, or for humanity itself, one of these Apostolic Delegates was driven out of the country; another, who because of illness had left the Republic for a short time, was forbidden to return, and the third was also treated in a most unfriendly manner and forced to leave. Surely there is no one who cannot understand that such acts as these, committed against illustrious personages who were both ready and willing to bring about peace, must be construed as a great affront to their dignity as Archbishops, to the high office which they filled, and particularly to Our authority which they represented.
