Think of it like this: if you attended an OF Mass in Germany, you would know exactly what was going on, even though you didn’t speak a word of German, because you’re thoroughly familiar with the liturgy. It’s not so different with the EF Mass. You know what is happening because you know what is going to happen. It isn’t as accessible as the OF in the vernacular, no doubt about that; there is prep work to do, even to reach the point where one can follow along in the missalette.
It seems like it would be a beautiful and extremely spiritual experience. However, do you risk missing out on learning???
The first time I attended one, it was not “a beautiful and extremely spiritual experience”; I had very little idea what was happening and found it impossible to follow along. (For instance, I didn’t realize that when they say the canon is silent, they really mean it.) It took a few times, and some research—reading through the Mass several times at sanctamissa.org and getting a feel for the overall structure of it—before it started to feel comfortable. It’s only once you reach that point that it becomes “a beautiful and extremely spiritual experience.”
Of course, what I forgot is that as a convert, my experience at my first few OF Masses was basically the same! Anything that is new to you will be difficult at first.
My suggestion is, find some videos online—youtube has a few, I think EWTN has one, the latin mass society has one—and watch so that you have some idea what you’re getting yourself into. Read through the Mass. As I said, SanctaMissa.org has the whole thing in parallel latin and english, and it has audio recordings so that you can hear how the latin sounds. Get yourself some “anchor points” so that if you get lost, you know that when you hear X, you should be on page Y. And then attend for real. Just have in mind that the first time is probably going to be quite difficult. It gets easier, though!
