46 Neither does the Church condemn those who, if it can be done without violation of justice, wish to make their country independent of any foreign or despotic power. Nor does she blame those who wish to assign to the State the power of self-government, and to its citizens the greatest possible measure of prosperity. The Church has always most faithfully fostered civil liberty, and this was seen especially in Italy, in the municipal prosperity, and wealth, and glory which were obtained at a time when the salutary power of the Church has spread, without opposition, to all parts of the State.
