Having been brought up Catholic (Conservative Novus Ordo), and then having been involved in the Catholic Traditional Movement, I can say I much preferred the Traditional Latin or "Tridentine" Mass. Without going in to great detail, let's just say there are multiple and grave issues inherent in the Novus Ordo, and in the Catholic Church in general since Vatican II. The Pslamist says "Worship the Lord in the beauty of Holiness...", I just never got a "beauty of holiness" from a Novus Ordo. The best Novus Ordo's I've seen are Pope Benedict's, EWTN's, and The NOM as offered at Holy Rosary in Indianapolis (interestingly the priest also offers the Traditional Mass daily as well). All in all, thanks, but no thanks!
While I understand the traditionalists point about maintaining latin (unity and the Decrees of Trent), I also feel that perhaps a reverent vernacular translation would have been in order perhaps leaving some latin hymnody and a few prayers (Pater Noster, Credo, Sanctus, Agnus Dei) as many ethnic Orthodox churches do now (75% English 25% Greek, Slavonic, etc). This is more in keeping with the older tradition of the church anyway. As for translation most Catholics had a Missal with latin on one page and the english on the opposite. It was BCP or "King's/Elizabethan" English. It was/is about Faith, not the Latin.
Now that I'm Orthodox, I rarely think or delve much in to the issues of Catholicism these days. I do pray for a return of tradition and sanity in the RCC. I have many friends and relatives who Catholics, and I pray for them. I am also grateful to the good priests and sisters who taught me about Our Lord, Our Lady, and the faith. I harbor no grudge or ill will toward Catholics. As I said before, I feel that rather than leaving Catholicism by becoming Orthodox, I've rather embraced it in its most full and traditional undiluted form!
