10 May God avert so terrible a misfortune! May all give a serious consideration to the evils by which in part we are afflicted, and with which in part we are threatened by those who, devoted t~ the interests of political sects, not of the public, have sworn to wage a war to the death against the Church. Unhappy men, if they were wise, if they had a true love for their country, far from distrusting the Church, and striving, under the influence of injurious suspicions, to deprive her of her necessary liberty, they would do all in their power to defend and protect her, and would first of all make provision for the re-establishment of the Roman Pontiff in the possession of his rights. In fact the more injurious the war against the Apostolic See is to the Church, the more fatal it is in the cause of Italy. We have elsewhere expressed this thought: "Say that the State in Italy can never prosper nor become stable and tranquil unless provision be made for the dignity of the Roman See and the liberty of the Supreme Pontiff, as every consideration of right requires."
