I admit that the “ut” you imagine to be essential is an accidental transcription error, and consequently, it’s omission could not possibly be invalidating.
Ignorant as usual ... and driven by your agenda.
Certainly the omission of "ut" could be invalidating. As Pope Pius XII taught about the essential form, there are two things required, the invocation of the Holy Ghost to produce the Sacramental effect.
Traditional Rite:
Invoking the Holy Ghost to make the man a priest.
Novus Ordo Rite:
Invoke the Holy Ghost. Ask (God?) that he be made a priest.
Problem is that the Holy Ghost can be invoked for any number of things. What's missing here is the notion that the Sacramental effect is being caused by the Holy Ghost.
If you hadn't been asleep in Latin class, the "ut" is very significant gramatically. It is not simply a random two-letter word. What follows the "ut" is the effect of the first part, "so that ...". This speaks directly to the link between the Holy Ghost and the Sacramental effect, which is severed by its removal. And the Holy Ghost causing the Sacramental effect is what Pius XII described as the essence of validity.
Now, it's POSSIBLE that it could be implied, but the problem is that it's not unequivocal. Holy Ghost could be asked to cause the proper dispositions in the priest, etc. or for any other reason than to effect the ordination.
So it's highly likely that this invalidates.
Also, just ask yourself, WHY did they remove this tiny little (as you claim insignificant) word? Did it somehow improve the Rite, make it more "Modern"? No, the nefarious sinister agents behind all of the V2 deformation of the Church did this ON PURPOSE. There's no other rational explanation for why the "ut" was in their way.
But then your view of the Crisis is that it was just a weakness of faith rather than a deliberate destruction by design.
