Elizabeth, I admire very much that you keep an open mind and even read these posts of mine.  Believe it or not I'm motivated by love for my fellow Catholics and not hate against those in SSPX ( now, there may be some skepticism towards the institution itself ).

To answer your questions, missing the "cleansing ritual" shows that SSPX just make up their own rules and then break them at will; that their theology is written on the fly.  This is a logical consequence of accepting that a man is Pope and then disobeying him, which throws apart any kind of balanced Catholic mentality.  

Think about it.  On the one hand, the SSPX claims that the VII Church is still the Catholic Church, so why perform what is an essentially an exorcism before celebrating Mass in one of their chapels?  Can Christ's true Church offer masses that are so foul that you need to "cleanse" after each one?  

On the other hand, if you think that VII is the real Church, well, then why NOT celebrate a Traditional Mass in the same church on the same day as a demonic "techno" mass?

The sign of the cross given by the Novus Ordo priest and followed by the FSSPX at Lourdes is significant as well -- very significant.  It's a sign of not only obedience but OBEISANCE given by the FSSPX religious to the VII "religious," whose "Christ" is a sham and ecuмenical Maitreya.  Does it not sound almost pre-planned, ALL the FSSPX religious crossing themselves when signalled to by a Novus Ordo priest, who is acting as their spokesman?  If I were there I would have charged at this "priest" and tackled him.  Okay, that was Internet bravado -- I would have glared at him sternly.  

It seems very ritualized to me.  First the FSSPXers go to an FSSPX Latin mass; then they take part in a pilgrimage bringing together the FSSPX with the Novus Ordo faithful; and then the FSSPX priests TAKE A BACK SEAT while a Novus Ordo "priest" does the honors and speaks for everyone there.  Notice how gradually the faithful are handed over from the FSSPX leaders to those of the Novus Ordo, while the FSSPX leaders actually show public deference to the Novus Ordo heretic.  

The article talks about a female FSSPX-er crying over this, and that many FSSPX laity travelled long distances and were upset as well.  But why should they be?  Again, the SSPX have never said VII is not the real Church; just the opposite, they act as if this ape Church is the Catholic Church.  So why shouldn't they ask their people to march along with Novus Ordo-ites?  I doubt many miracles happened that day.

One interesting detail in this article.  I learned that when the Novus Ordo-ites of France recite the joyous mysteries of the Rosary, they have a particular way of saying them.  Not only do they throw in strange "Aves" and "Glorias," but they use the informal "tu" form when speaking to Christ, instead of the formal "vous."  This is like, in English, if we dropped all the "thous" and "thees" except much worse.  In France it is a TERRIBLE insult to use the "tu" form with a boss or superior or stranger; I vaguely remember a French movie where one woman uses it on another, cattily, only to end up getting her hair pulled with vicious rage.  You do NOT "tutoyer" or use the "tu" form with anyone except a friend or family member or someone you are very familiar with, unless you are openly trying to disrespect them.  If I used the "tu" form on a stranger it would be like saying "Oh, do you really think so, little man?" IT IS UNBELIEVEABLY CONDESCENDING.  

In formal settings, it is not used but only "vous."  I doubt that in better days you would ever have even used it with a priest who has been friends with your family for years and years.  Yet VII Catholics speak to the Divine King of Heaven and Earth with the "tu" form.  Undoubtedly the excuse is that Christ is their "friend" and they don't need to be fearful around Him -- well, you be the judge of that.  The more you know French, the more you will feel the shock of this outrage.  The FSSPX-ers had to listen to Christ being informally greeted as if He were Joe Blow from down the street.

Granted, this article is from a website that does sniff around the FSSPX like a bloodhound.  But they are actually less harsh on SSPX than me because they think that Abp. Lefebvre has been betrayed while I think that SSPX was incoherent even under Abp. Lefebvre.  I don't say this to spout agit-prop but in hopes at least one small part of it triggers something in someone's mind out there.
