The Catholic Church celebrates in Latin for a variety of reasons: 1. Because she did so in the beginning; and as she never changes her faith (!), she has "never" deemed it advisable to change her language. If her sacred language changed with those that are changing around her, there would be no end to the "resulting confusion", and much disedification would unavoidably be given by using words and phrases in the hearing of the people to which the grossest meanings are sometimes attached. 2. As order is Heaven's first law, uniformity seems to be the first law of the Church, and for this reason she endeavors to have her greatest charge, the due and respectful celebration of the Adorable Sacrifice of the Altar, conducted with the same ceremonies and said in the same language everywhere. This she could not do unless she had fixed on a common language. 3. Unity in respect to language goes very far in "Preserving unity of belief." A writer of high repute declares as his firm conviction that the various Churches of the East that have severed their connection with the centre of unity, Rome, would hardly ever have done so had they been required from the beginning to make Latin their liturgical language. National languages always pave the way for "national Churches". 4. By preserving the Latin in the liturgy, and requiring her ministers to cultivate it, the Catholic Church has secured for herself the accumulated literary treasures of eighteen centuries of Christianity. By this she has free access to the writings of some of the most illustrious Doctors of the Church, to Canon and civil law, to the decrees of ancient Councils, and to many other documents of value which would otherwise have been totally out of reach. For this reason alone our Holy Church should receive the praise of Christendom. Hallam, in his "Middle Ages," could not hide the fact that the sole hope of literature in those times depended chiefly on the Catholic Church; for, wherever it existed, the Latin language was preserved.

(We are adding this note, so that the reader will ponder, from reading the above, why the Vatican II Reformers would take up such a task as to change the ancient language of the Church. It was certainly not to retain the faith in it's entirety, but, rather, as quoted above to decimate "unity of belief", disedify the faithful, to change the faith, to discredit the ancient writers of the Catholic Faith by no longer teaching a dead language used by the Catholic Faith for full 2,000 years., to nationalize Churches, in other words, "TO DESTROY THE FAITH")
