Of its very nature Latin is most suitable for promoting every form of culture among peoples. It gives rise to no jealousies. It does not favor any one nation, but presents itself with equal impartiality to all and is equally acceptable to all.
These are the words of Our Predecessor Pius XI, who conducted a scientific inquiry into this whole subject, and indicated three qualities of the Latin language which harmonize to a remarkable degree with the Church’s nature. “For the Church, precisely because it embraces all nations and is destined to endure to the end of time … of its very nature requires a language which is universal, immutable, and non-vernacular.”7
Modern languages are liable to change, and no single one of them is superior to the others in authority. Thus if the truths of the Catholic Church were entrusted to an unspecified number of them, the meaning of these truths, varied as they are, would not be manifested to everyone with sufficient clarity and precision. There would, moreover, be no language which could serve as a common and constant norm by which to gauge the exact meaning of other renderings.
But Latin is indeed such a language. It is set and unchanging. it has long since ceased to be affected by those alterations in the meaning of words which are the normal result of daily, popular use.
It is also a most effective bond, binding the Church of today with that of the past and of the future in wonderful continuity.
