102 Let us then, Venerable Brethren, raise our hands and our hearts in supplication to heaven, "to the Shepherd and Bishop of our Souls," to the divine King "who gives laws to rulers," that in His almighty power He may cause these splendid fruits of Christian education to be gathered in ever greater abundance "in the whole world," for the lasting benefit of individuals and of nations. As a pledge of these heavenly favors, with paternal affection We impart to you, Venerable Brethren, to your clergy and your people, the Apostolic Benediction. Given at Rome, at St. Peter's, the thirty-first day of December, in the year 1929, the eighth of Our Pontificate.
