Frankly, this is all wrong thinking that is against Catholic principle and teaching.
Never, NEVER, can anyone simultaneously acknowledge that there exists an "authority" one can communicate with while saying one will not ask for permission to consecrate a bishop. That is objectively sinful and schismatic, and you will not find one quote to support such a thing. Not one.
Docuмents during the Communists reigns in Mexico, Russian and China ( up to about 1958 ) clearly show this.
Only the Catholic principle of epikeia can allow the consecration of a bishop WHEN there is no pope, and the election of another is dismal.
Says your sedevacantist rhetoric. If you are indeed "nado", then you are a sedevacantist who participated in many SGG-themed discussions.
The Conciliar Church actually says that +ABL's consecration wasn't schismatic, though they won't advertise that. In fact, they go out of their way to make people assume that it is schismatic, without ever saying it explicitly or officially.
For example, the popes considered the situation with +Lefebvre and the SSPX to be an "internal Church matter" and not matter for the congregation that deals with schismatic churches, other religions, etc.
That is why +Lefebvre never got a trial. Do you realize that every excommunicate and heretic declared as such by the Church ALWAYS got a trial to define and reject their errors and heresies? But the Church authorities knew that +ABL was guilty of no heresy, and in fact it was THEY who would come out looking like heretics. So he never got a trial. Therefore they used propaganda, misdirection, mental reservation, "letting people assume the wrong thing", etc. to get their deeds done.
The same with the Latin Mass itself. If you go up the chain, you will eventually be told that the Tridentine Mass was never abrogated. However, they want the word on the street -- the common belief taken to be the truth -- to be PRECISELY that the Tridentine Mass was done away with.
In conclusion, if +Lefebvre wasn't a schismatic (and it appears that even according to the Conciliar Church he is not), then neither are +Williamson, +Zendejas, +Faure, and +Thomas Aquinas.
