Do some TLM priests (sede, SSPX, FSSP, etc.) skip entire prayers in order to shorten Mass? I've been told that this was a common thing before the NO; some priests would make themselves popular by shaving off 15 minutes or so from Sunday Mass with the assumption that most of the faithful wouldn't notice because they wouldn't know Latin.
They didn't *shave off prayers*, as that would cause twinges of conscience, etc.
What they did was *rush through them* at a pace that would make an auctioneer jealous. When reciting the prayers of the Canon, for example, the priest is saying them in a low whisper so no one is going to hear how fast he is going.
And yes, the priest with the shorter Mass was more popular, because MOST CATHOLICS are not heroic, devout, or saintly. Sanctity has always been rare, from the earliest ages of the Church until the present day.
That's why the Church holds the saints up as models -- they're literally HEROES of virtue. Heroes are not commonplace, or they wouldn't be heroes.
