1 But a short time ago, as you well know, We, by letters apostolic, and following the custom and ordinances of Our predecessors, commanded the celebration in this city, at no distant date, of a Holy Year. And now to-day, in the hope and with the object that this religious celebration shall be more devoutly performed, We have traced and recommended a striking design from which, if all shall follow it out with hearty good will, We not unreasonably expect extraordinary and lasting benefits for Christendom in the first place and also for the whole human race.
