I think what you're referring to was in the same thread. https://www.cathinfo.com/crisis-in-the-church/bp-neal-webster/15/
Yes, same thread. I can't recall if he posted it here or whether he sent it to me by PM, but it certainly looked legitimate.
At that point, the priesthood of Terrasson was the missing link, and that was just because there was no mention of it on the "Boyle" site. Just mentioned he had been ordained by Laborie (which is where the doubt would come in, since Laborie came through Old Catholic / Gallican lines).
Now, the early consecrations performed by Clemente were trustworthy, since he was assisted either by Bishop Sandler or Bishop Puga, both of whom had been Roman Rite priests (ordained well before Vatican II) for many years.
Question is how much those two kept an eye on Clemente during the conditional ordination, since the assistants there do not generally co-ordain (as they would co-consecrate), though I suspect probably valid given that Clemente, being a Spanish speaker, likely did not butcher the essential form too badly.
So my final verdict is probably valid, but with just enough positive doubt that I'd only ask them for Sacraments in danger of death ... since it is possible Clemente would have botched the conditional.
What's funny, though, is that the initial ordinations/consecration by +Thuc of Clemente and the others (Sandler, Puga, et al.) were 1000% valid even by Bishop Kelly's invented standards, with MANY witnesses, including competent ones (assistant priests ... ordained/trained before Vatican II). So Clemente was 100% undoubtedly a valid bishop, with the big question mark being his training.
Now, after the first furious round of ordinations/consecrations by Clemente (with Sandler/Puga assisting), they started tampering with the Rites and it's anybody's guess after that.
With regard to Bishop? Pfeiffer, I've heard two different stories, in addition to Bishop?'s insistence the first try was valid, namely ...
1) that they did it again in the Sacristy after the Consecration (since they caught it themselves ... even though evidently there was nothing to catch)
2) that they did it again the next day (after people went through the video and realized the problem)
But I've heard of no witnesses to the retries ... would would have been easy to film, and given how badly it was messed up the first time, whose word would we take that it was done right the secondt time, since Bishop? Pfeiffer insists the first one was good enough (contrary to everyone else's opinion).
