4 Our thought, therefore, is fixed in the first place on those who must be the light that illuminates, the salt which conserves, the good leaven which penetrates the entire mass of the Faithful: We mean your priests. In truth, We know how tenaciously and at the cost of how many sacrifices you care for the selection and increase of sacerdotal vocations, in the midst of all sorts of difficulties, well persuaded as you are thus to provide the solution of a vital problem, truly the most vital of all the problems relating to the future of the Church. In view of the almost absolute impossibility of having in your own country wellordered and tranquil seminaries, you have found in this city an ample and gracious refuge in the South American Pio Latino College, which has formed and continues to form in science and virtue so many worthy priests and which, for its precious work, is particularly dear to Us. But since in many cases it has been impossible to send your students to Rome, you have worked solicitously to find an asylum in the hospitality of a great neighboring nation.
