The Catholic tradition has been to hold fast to what has been handed down and look upon any novelty with the utmost suspicion. Any rude handling of such forms must cause deep pain to those who know and use them. For they come to them from God through Christ and through the Church. But they would not have such an attraction were they not also sanctified by the piety of so many generations who have prayed in the same words and found in them steadiness in joy and consolation in sorrow. In short, the Missal of 1570 was, in all essentials, the usage of the mainstream of medieval European liturgy which included England and all its rites.
Later revisions are of slight importance.
No doubt in every reform one may find something that one would have preferred not to change. Still, a just and reasonable criticism will admit that Pius V's restoration was on the whole eminently satisfactory. The standard of the commission was antiquity. Certainly we in the West may be very glad that we have the Roman rite in the form of Pius V's Missal.
