2 On the other hand the Holy See has spared absolutely no means to avert this great calamity. While it was untiring in warning those who were at the head of affairs in France, and in conjuring them over and over again to weigh well the immensity of the evils that would infallibly result from their separatist policy, it at the same time lavished upon France the most striking proofs of indulgent affection. It has then reason to hope that gratitude would have stayed those politicians on their downward path, and brought them at last to relinquish their designs. But all has been in vain - the attentions, good offices, and efforts of Our Predecessor and Ourself. The enemies of religion have succeeded at last in effecting by violence what they have long desired, in defiance of your rights as a Catholic nation and of the wishes of all who think rightly. At a moment of such gravity for the Church, therefore, filled with the sense of Our Apostolic responsibility, We have considered it Our duty to raise Our voice and to open Our heart to you, Venerable Brethren, and to your clergy and people - to all of you whom We have ever cherished with special affection but whom We now, as is only right, love more tenderly than ever.
