After much contemplation, it is Our considered belief that further strife in Italy will not further any legitimate end beyond killing Our faithful Catholic subjects and promoting disharmony and negative feelings between the noble monarchs of Our Holy Roman Church.
Therefore, We call for an immediate end to hostilities in Italy between the Austrian Emperor, the King of Sardinia-Piedmont, and the King of the Two Sicilies. Furthermore, We invite representatives from each monarch to join Us in the Lateran Palace in Rome, with Our promise of safe passage, to conduct negotiations for a lasting and permanent peace in the Italian Peninsula.
Should any monarch or officer thereof order their soldiers to defy Our will for peace and amity among their Christian brothers without first sitting at Our table to discuss their differences, We shall exercise our authority as God's Vice-Regent on Earth and Bishop of Rome to bar them from receiving the sacraments or absolution in Our Holy Church. Any soldier, officer, or nobleman who acts in violation of Our will shall die unshriven and will not enter the Kingdom of Heaven.
Gregory XVI, Bishop of Rome, Supreme Pontiff of the Universal Church and Sovereign of the Papal States
