At Mass on Sunday, I realized that that would be the last time I ever heard the liturgy in the only translation I've ever known. I learned all the prayers and responses in the Mass when I made my first communion, back in second grade. I've had it memorized ever since. I have to admit that I am a tad anxious about things changing, about feeling like a "visitor" to the liturgy (sort of like when I once attended Mass in the extraordinary form :) ). Being a lifelong Catholic, that does have a disconcerting feel to it.
Our parish has been slowly incorporating in the new music, and I recently purchased a new missal that has all of the new responses in it. So I'll be well armed on the First Sunday of Advent. I guess I'm a tad excited too, to have something "fresh" in our liturgy, and I've been enjoying reading the articles in the newspaper about the coming changes. (we live in a very Catholic area; this actually is big news here. :) ).
So we'll see how it goes. I've been encouraged by what I've heard on my Catholic podcasts and other Catholic reading about the translation being a closer pairing with the original Latin, and closer to Scripture. Good stuff.
