24. We wish to point out this state of things to our children in Italy and in other nations. To all of them, however, we would say that if Our sorrow is great, not less great is Our courage, nor less firm Our confidence in that Providence which governs the world, which so constantly and lovingly watches over the Church and which identifies itself with the Papacy according to the beautiful works of St. Ambrose "Ubi Petrus, ibi Ecclesia." Both are divine institutions which have outlived every outrage and attack and which have seen the centuries go by unshaken, drawing from their misfortunes fresh force, energy and constancy.
