Second—The Catholic Church is spread over the whole world, embracing in its fold children of all climes and nations, and peoples and tongues under the sun. How, I ask, could the Bishops of these various countries communicate with one another in council if they had not one language to serve as a common medium of communication? It would be simply impossible. A church that is universal must have a universal tongue; whilst a national church, or a church whose members speak one and the same language, and whose doctrines conveniently change to suit the times, can safely adopt the vernacular tongue in its liturgy. 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.
