Disclaimer: this is just my reasoned opinion. I give my assent to the Church’s wisdom in all things.
Latin has pride of place and is praised as a beautiful language because, well, it has pride of place and is beautiful. It has been the Church’s mode of communication for centuries. It lends itself well to singing, I personally love to sing Latin in choir. There were good reasons for Latin attaining this pride of place many centuries ago. Those reasons may or may not be present any longer.
Given that the Church recognizes Latin in this special way, the current -practices- of the Church also have an inspired wisdom. There are good reasons the Mass, in actual practice, is said mostly in the vernacular. It is not simply a revolt against tradition as is so often suggested. What are those reasons? and what do they say about how we communicate with one another compared to centuries past? Are the same cultural factors in place as they were centuries ago? Since the Mass is Christ’s sacrifice for all people, isn’t there a wisdom in making that sacrifice more intelligible and approachable for a people that can read, write, print, speak, their own languages? So that they may be drawn to salvation?
In our parish, there are those who detest any traditional way of doing things. There are those who would like to go back. Our Spanish community has a cohesive identity they do not want to lose. Language is a big part of that for them. So, I personally would like Latin period, but I do not think it will be, ever, and I am not sure it would be a wise thing. So as the Church does, so I will accept.
