"‘In his record of the peoples and princes the Lord shall tell of these who have been born in her.’ Now the psalm did not say, those who are born in her, but who have been born in her. ‘The Lord shall tell.’ How shall he tell? Not by word of mouth, but in His writings. In His writings of whom? Of the peoples. That is not enough, for it also speaks of the princes. And which princes? Those who are born in her? No, it did not say that; but, those who have been born in her."

Jerome then goes on to say a few sentences later in the same homily...
"‘‘In his record of the peoples the Lord shall tell’: in the sacred writings, in His Scripture that is read to all peoples in order that all may know. Thus the apostles have written; thus the Lord Himself has spoken, not merely for a few, but that all might know and understand. Plato wrote books, but he did not write for all people but only for a few, for there are not many more than two or three men who know him. But the princes of the Church and the princes of Christ did not write only for the few, but for everyone without exception. ‘And princes’: the apostles and evangelists. ‘Of those who have been born in her.’ Note ‘who have been’ and not ‘who are.’ That is to make sure that, with the exception of the apostles, whatever else is said afterwards should be removed and not, later on, hold the force of authority. No matter how holy anyone may be after the time of the apostles, no matter how eloquent, he does not have authority, for ‘in his record of the peoples and princes the Lord shall tell of those who have been born in her.’
