I don’t dislike the TLM, but isn’t the reason fairly simple? It doesn’t have to do with the collapse of tradition or anything like that. Yes, the Church does allow other liturgies, especially in Eastern Catholicism. There are a few other examples, but can we really be ONE Church with two Masses side by side? I suppose if it were 1570 instead of 2007 and if folks had the internet back then, they would be criticizing Pope St. Pius V for the “innovations” in his new Mass? If we go back to the TLM, then the next thing someone will want is to do the Ambrosian Mass or the Mass of Pope St. Gregory the Great. Where does it all stop? Every parish will do its own favorite version of the Mass. If Pope St. Pius V can, based on the Council of Trent, promulgate a Mass, then so could Paul VI. And, if you REALLY study the developement of the liturgy, the NO is no more or less less “organic” than the TLM. One other pont, as soon as the TLM is more freely allowed, there will be abuses in it. There were abuses before V2!!! What the Church should do is demand that priests adhere to the GIRM and the rubrics of the NO.
At the risk of being divisive, as I hope for nothing more than reunion with the Orthodox, it is amusing to hear Orthodox lecturing Roman Cahtolics on tradition. There isn’t ONE Orthodox Church! It is bitterly fractured and splintered along ethnic and nationalistic lines that are worse than some of the divides in western Christianity. If that is what the Orthodox tradition has produced and called the apostolic succession, then let’s have to part of it in the Latin Church.
