A few years ago a Convocation was held in England, composed of British and American Episcopal Bishops. They had no difficulty in communicating with one another because all spoke their mother tongue. But suppose they had representatives from Spain, France and Germany. The lips of those Continental Bishops would be sealed because they could not speak to their English brothers; their ears also would be sealed because they could not comprehend what was said to them.
In 1869, at the Ecumenical Council of the Vatican, were assembled Bishops from all parts of the world speaking all the civilized languages of Christendom. Had those Bishops no uniform language to express their thoughts, public debates and familiar conversation among them would have been impracticable. The Council Chamber would have been a confused Babel of tongues. But, thanks to the Latin language, which they all spoke (except a few Orientals), their speeches were as plainly understood as if each had spoken in his native dialect.
Third--Moreover, the Bishops and Clergy of the Catholic Church are in frequent correspondence with the Holy See. This requires that they should communicate in one uniform language, otherwise the Pope would be compelled to employ secretaries speaking every language in Christendom.
But if the Priest says Mass in an unknown tongue, are not the people thereby kept in ignorance of what he says, and is not their time wasted in Church? We are forced to smile at such charges, which are flippantly repeated from year to year. These assertions arise from a total ignorance of the Mass. Many Protestants imagine that the essence of public worship consists in a sermon. Hence, to their minds, the primary duty of a congregation is to listen to a discourse from the pulpit. Prayer, on the contrary, according to Catholic teaching, is the most essential duty of a congregation, though they are also regularly instructed by sermons. Now, what is the Mass? It is not a sermon, but it is a sacrifice of prayer which the Priest offers up to God for himself and the people. When the Priest says Mass he is speaking not to the people, but to God, to whom all languages are equally intelligible.
The congregation, indeed, could not be expected to hear the Priest, even if he spoke in English, since his face is turned from them, and the greater part of what he says is pronounced in an undertone. And this was the system of worship God ordained in the ancient dispensation, as we learn from the Old Testament and from the first chapter of St. Luke. The Priest offered sacrifice and prayed for the people in the sanctuary, while they prayed at a distance in the court. In all the schismatic churches of the East the Priest in the public service prays not in the vulgar, but in a dead language. Such, also, is the practice in the Jewish synagogues at this day. The Rabbi reads the prayers in Hebrew, a language with which many of the congregation are not familiar.
