There's more to 'sacred time, sacred space, sacred language' than "Tradition." That sort of reduction-to-pragmatism is dangerous for both the 'conservatives' and the 'liberals,' but is quite common in the USA.
Orthodox Jewry regards the Sabbath rest in a different way than Americans do, for example. Their take is not "rest from labor;" it's far more encompassing--sort of a "let go, let G-d [do what He wills]" weltanschauung.
The American 'positivism' infects far more than just the laws.
So why is Latin "sacred"?? It wasn't the first language of the church (as Arabic is for Muslims). The first pope (Peter) probably didn't even speak it. Probably the only one of the early church fathers who did was Paul. The sole reason IS tradition. There is nothing "magic" (or even special) about Latin.
Even more than that: "The Jews keep the Sabbath, and the Sabbath keeps the Jews."
