1 In our desire to enrich the crown of your holy joy We cross in spirit the vast spaces of the seas and find Ourselves in your midst as you celebrate, in company with all your faithful people, the one hundred and fiftieth anniversary of the establishment of the Ecclesiastical Hierarchy in the United States of America. And this We do with great gladness, because an occasion is thus afforded Us, as gratifying as it is solemn, of giving public testimony of Our esteem and Our affection for the youthfully vigorous and illustrious American people.
