Latin in the Mass?

"The Eucharistic celebration is to be carried out in the Latin language." -Code of Canon Law (Canon, 928). "The use of the Latin language is to be preserved in the Latin rites." -Vatican Council II (Sacrosanctum Concilium, 36). "The Latin language still holds primacy of place as that language which, based on principle, the Church prefers." -Mons. Guido Marini (Liturgy Conference at Mileto). "The Roman Church has special obligations towards Latin, the splendid language of ancient Rome, and she must manifest them whenever the occasion presents itself." -Pope John Paul II (Dominicae Cenae, 10). "I ask that future priests, from their time in the seminary, receive the preparation needed to understand and celebrate Mass in Latin, and also to use Latin texts and execute Gregorian chant." -Pope Benedict XVI (Sacramentum Caritatis, 62).
