16 As to what pertains more nearly to your people, in former letters and similar pronouncements, We have denounced dangers from which religion should be protected, and We have proposed aids which would lead more suitably to its freedom and dignity. And since civil affairs cannot be separated from religious, We have been extremely eager to give Our attention and help to the former as well, since this is clearly an integral part of Our Apostolic duty. For the frequent advice and commands which We gave you as your circumstances required, contributed not a little, as you rightly remember, to the public safety and prosperity as well. But if, in this very people, the actions of good men comply more strongly each day with Our advice and warnings, why should We not embrace the hope which blossoms more abundantly on the occasion of this secular commemoration, and which foreshadows to a rapid fulfillment of all men's prayers? For surely all good citizens pray that by removing causes for disagreement, the Church will not be denied its proper honor. Then the proper honor of the state too will shine more brilliantly in alliance with and under the guidance of the ancestral religion. This will result in the authority of governments, the mutual duties of the classes, the education of youth, and many other matters like these maintaining themselves in truth, in justice, and in love: for on these foundations and supports especially, states depend and thrive.
