Bp. Williamson says the significant form, it's practically the same, just one or two sentences, often just one sentence, in this case it may be two sentences, one or two sentences ... and then an et instead of an ut, and he considers that the Novus Ordo ordination form in Latin is stronger than the old form?

He says that the NO ordination is "stronger"? No, there's no
et ... just a simple removal of the
ut. So, why exactly would they go to the trouble of removing a single two-letter word? That speaks volumes. But if you examine the meaning of the
ut, "so that," it's this expression that indicates the Sacramental effect.
It's the difference between (major paraphrase)
"May he receive the Holy Ghost. May he become a priest."
vs.
"May he receive the Holy Ghost so that he may become a priest." (i.e., may the Holy Ghost make him a priest)
Pius XII when discussing the essential form indicated that the form indicates that the action of the Holy Spirit brings about the effect of the man being ordained to the priesthood. But here the causal connection is severed and it can be viewed as two separate and independent prayers. We can receive the Holy Ghost for any number of purposes, including, for instance, at confirmation.
I find this Rite to be clearly INVALID.
