Whatever you do, don’t miss the consecration by trying to follow the Canon in the Missal. The Canon is the silent part of the Mass where the consecration occurs, so just let that awesome moment happen and take it in without worrrying about the Missal. You will never forget this!
There are dozens of sites on the internet that you can read the Mass online, so you can have an idea of what is being said before you get there.
The first thing you could learn to say (or sing, at a High sung Mass) is “Et cum Spiritu tuo” (And with thy Spirit) whenever the Priest says “Dominus vobiscum” (The Lord be with you). That will be enough to learn for week one. I think it would be safe to bet that there will be a week two, three and four etc.for you too!
I was in speechless awe after my first Latin Mass, which was a low Mass, and have not looked back. I am excited all over again for you!
