I don’t think he was raised that way, but maybe he was a childhood liar and it wasn’t caught, so it developed into a vice.  PTM encourages him in wrong-doing.

You posted this just as I was writing my own response.  We're on the same page here.  There's a very fine line between seeking episcopal consecration for the genuine good of souls and seeking it for one's own personal glory.  And the devil is very skilled at blurring this line, convincing a person seeking out of self-will that it's actually being done for the good of souls.

When I saw him offer Mass as a priest in 2007, I was horrified at how irreverent his Low Mass was. To this day I haven't seen a priest who raced through a Mass nearly as fast. He sounded like a two-bit auctioneer.

I think Seraphina is on to something. A deep flaw was never properly addressed in this man, probably from before he entered the seminary. Hindsight is... what it is... but looking back I suspect he never had an actual vocation. Considering all the damage he's done, it would have been better had he never been a priest at all.

Pablo may turn out to be his just reward for a career bent on building his own cult of personality. He certainly aided the "cult" aspect.

You must have never seen the low mass of Fr. Asher.  20 min.  I kid you not.

Yes, I am sure Seraphina is on to something, too, but I think it is more related to his unnatural attachment to Paul Hernandez, "lay exorcist", "pablo the mexican".
.
Fr. Pfeiffer has much too much pride, as evidenced in his searching for consecration these last eight years, at least.

I have been told that:

Concerning Fr Pfeiffer's consecration, Fr Hewko does not seem to be correct on Abp Lefebvre's views on
Abp Thuc. Mr Lundberg, a Lutheran scholar and professor on Christianity, takes an interest in the
Catholic Traditional movement.

Opinions?

Hopefully his episcopal orders are valid
The consecration is not valid until Fr. Pfeiffer proves it is valid.

and even more hopefully he wont bring the Traditional Catholic movement into any disrepute.
Too late....

I could see a priest, in some cases, offer Mass quickly ... for the benefit of the faithful.  Let's say you have an early morning Mass and people need to be at work soon afterwards.  Priests are taught that the Mass is not their own persona prayer time, but the public prayer of the Church, and also offered for the benefit of the faithful (except at private Masses).  Now, with that said, you can't give the impression of being irreverent and sloppy ... for the same reason, that it's the public prayer of the Church.  So a balance must be found between length and reverence.  If I'm a priest, I can't just go off and decide to mediate for 15 minutes during the middle of the Canon right before the consecration or something (yes, I know, some saints were drawn into ecstatic states, but those are special cases) ... making people late for work or else forcing parents to deal with antsy toddlers for an extended period of time.

As a priest, I might WANT to take my time and read the entire Mass slowly while meditating on each phrase, but I make the sacrifice of not doing my own will but instead doing what's in the best interests of the faithful.

Sure, but a 20 min mass CANNOT be said reverently, nor can the laity participate at all.
.
But just because a mass is said slowly does not mean it is reverent.  I recall Fr. Pazat, sspx.  He would heave a loud heavy sigh before each sentence of the mass.  The mass took a long time, but it was the most irreverent mass I have ever been to.
