The great Klaus Gamber, the twentieth century's foremost liturgist along with Josef Jungmann, called the Novus Ordo a tragic break with Catholic Tradition--and he was referring to its Latin version. He called it "frightening." He also said that a Catholic from the past, entering a Catholic church today, "would feel as if he had entered a strange, foreign place. He would think that he must have come to the wrong address and that he accidentally ended up in some other Christian religious community." (Reform of the Roman Liturgy, Harrison, NY, p. 107.)

Yes. So?

Is Gamber denying validity? liceity? NOPE.

But Gamber is right.
