Since the priests and bishops after V2 see that Rome doesn't appear to be Catholic, then they will perform Catholic sacraments in an "emergency state". This means the Faithful, who can't find a "true priest" will ask to be provided one to perform all needed Sacraments in a state of emergency without jurisdiction. If they need a priest, they have to ask a bishop to help get them one, because a "true Bishop" can only make "true priests". This is what we base our ideas on to justify being outside of Rome. I know I don't have the most perfect words to explain this, but the Faithful are required to ask for the Sacraments and the Priests should provide them, regardless of what the "true theological position is", because we do not have an authority to tell us which of us are right and which of us are wrong.
Period end of story.
All of the groups outside of Rome are continuing the Catholic Church in this way, but they spend more time fighting over "unapproved theological positions" and less time making sure all of the Faithful are getting the sacraments they need. It shouldn't be that I have access to 5 priests (all with different positions) and some have no priests. And the Faithful should accept all "true priests" regardless of differences in these "unapproved theological positions" because the "True Sacraments" bring down graces that we need for the spiritual battle we are currently fighting.
You said you need help, Gray, but clearly you have your opinion all worked out, along with the husband you said you must follow.
However, it is abundantly clear that you are here as an apologist for the sedevacantist position. Why pretend otherwise?
