“For the Church, since it contains all nations in its embrace, since it is going to endure until the consummation of the ages, and since it utterly excludes the common people from its governance, requires by its own nature a universal language, unchangeable, not that of the common people”.
“Since Latin is such a language, it was divinely foreseen that it should be something marvellously useful for the Church as teacher… that they might easily compare the respective thoughts and insights of their minds, but also – and this is even more important – something with which they might understand more profoundly the things of mother Church, and might be united more closely with the head of the Church”. ~ Pope Pius XI
