The architect for this project was Azar/Walsh (Kevin Walsh and Kamal Azar) both of whom are my parishioners at St. Joseph Church, Macon, Georgia!!!!!
But I digress.
As a booming parish, St. Teresa's has a huge Hispanic ministry (mostly Mexicans) and a large Vietnamese Community in addition to the majority Anglo community. So the Liturgy of Dedication tried to reflect this diversity.
The first reading was in Vietnamese (the program had the English translation). The second reading was in Spanish.
The hymns and anthems were in the various languages. The parts of the Mass, Gloria, Sanctus, and the Mystery of Faith were in English. The Agnus Dei was in Latin. Thus the Agnus Dei was powerfully sung by all of us, no matter our native tongue! That highlighted for me the genius behind Latin in a multi-language parish!!!!!
And thus I opine. The problem with a parish with multiple choirs and choir directors is that there is rivalry even if there aren't different language groups. Why in the name of God and all that is holy does there need to be slots for the various choirs to sing at any Mass? Why can't the the boss, the music director say, we are all coming together and we're singing in unity and this is the way it will be.
My recommendation and I wish it were the case for the entire diocese now is that at any multi-language Mass at the Cathedral or elsewhere, is that the Jubilatio Deo parts of the Mass be known by every Catholic, no matter their language, in the Diocese. And at these events, the Kyrie, Gloria, Credo, Sanctus, Mystery of Faith, Pater Noster and Agnus Dei would be chanted in Latin by everyone!
The Propers in Latin would be chanted by a schola or choir.
This would thus leave room enough for the differing languages to have hymns in their respective language at the procession (prior to the Introit), at the offertory and at communion. And of course there could be prelude to the Mass with this, that or the other choir singing their favorite ethnic hymn.
This seems like a no-brainer to me!
