Invalid episcopal consecrations, taken alone, would only impact the status Ratzinger & Bergoglio vis a vis the papacy. Not all the way back to 1958, right?
I don’t understand your last paragraph. Are you saying new rite concecrations were more likely invalid in the seventies and eighties than now?
Because it was closer to the time of the Council when a lot of them still publicly exercised their ministry - only one or two decades after when the post-Council heresy was at its worst. And many of them were either complete pederasts, heretics or both.
There would still be enough time for someone to think that maybe this would be resolved because they were still alive and we'd return to a semblance of normalcy.
But today, I would have a lot of doubts because it's been 50 years, most of them are retired and/or dead and the New Rite has not been abandoned.
