Princeps Pastorum §2

² The Most Provident Lord, in His secret and loving designs, willed that, in its very first years, Our priestly mission should be oriented toward the furthering of this cause; in fact, immediately after the conclusion of the First World War, Our predecessor Benedict XV called Us to Rome from Our diocese, so that We could devote Our zeal to the Pontifical Congregation for the Propagation of the Faith, a function which We most willingly performed during four years of Our priestly life. We happily recall Whitsunday in 1922, the third centenary of the foundation of the Congregation for the Propagation of the Faith, which is especially entrusted with the task of carrying the beneficial light of the Gospel, and heavenly grace, to the farthest reaches of the earth. It was with great joy that We participated in the Congregation's centennial festivities on that day.
