17 But We must, in obedience to an inner prompting, make special mention of Our gratitude for the tokens of reverent homage which we have had from the Sovereigns, heads of States and Governments of those nations with which the Holy See is in friendly relations. Our heart is joyous especially at the thought that We can, in this first Encyclical directed to the whole Christian people scattered over the world, rank among such friendly powers Our dear Italy, fruitful garden of the Faith, which was planted by the Princes of the Apostles. For, as a result of the Lateran Pacts, her representative occupies a place of honor among those officially accredited to the Apostolic See. "The Peace of Christ restored to Italy," like a new dawn of brotherly union in religious and in civil intercourse, had its beginning in these Pacts. We pray God that, in the serene atmosphere of that peace, He may pervade, revivify, strengthen and fortify the hearts of the Italian people, so close to Us, in the midst of which We live, with which We share the very air We breathe. We hope and trust that people, so dear to Our predecessors and to Us, may be faithful to its glorious Catholic tradition, and experience through the Divine Protection ever more that truth of the Psalmist: "Happy is that people whose God is the Lord" ( Psalm cxiii. 15).
