"If the theology behind the Mass of Paul VI is substantially different — if it does not, in a word, reflect Catholic doctrine — the practical consequences are obvious. A Catholic cannot merely prefer the old rite to the new; he must also reject the new rite in its entirety. The faith obliges him to do so."
Fr. Anthony Cekada
