“We must say it plainly: the Roman rite as we knew it exists no more. It has gone. Some walls of the structure have fallen, others have been altered—we can look at it as a ruin or as the partial foundation of a new building. Think back, if you remember it, to the Latin sung High Mass with Gregorian chant. Compare it with the modern post-Vatican II Mass. It is not only the words, but also the tunes and even certain actions that are different. In fact it is a different liturgy of the Mass.”
— Fr. Joseph Gelineau (1978)
