1 By the inscrutable design of Divine Providence We were raised to this summit of the Catholic priesthood. From that moment Our thoughts were turned to all the innumerable children whom God entrusted to Us. Yet, in a special way, We have felt an affectionate and earnest solicitude towards those who have the commission to be "the salt of the earth and the light of the world," for those who have been signaled out and adorned by the priestly character. In a still more special way Our thoughts have turned towards those dearly beloved young students who are being educated in the shadow of the sanctuary and are preparing themselves for this most noble charge, the priesthood.
