I believe the main point here is that Father is SV. He believes the chair is vacant regardless of what he thinks of the previous posers. It is an honest admission that he knows will have consequences. I hope this helps unify all of people of good will in regards to understanding the root cause of the problems within in the structures that were formerly inhabited by Catholics is that the head of that formerly Catholic institution is not the Pope. Once this is realized by all the good-willed Catholics we can, in addition to realizing why all this bad stuff has gone on in the "Church" move past this time-consuming debate and discuss the next step. Once realizing this fact what, if anything, would be God's will for us to do about it apart from being the best Catholics we can be.
I mean does being the best Catholic we can be include trying to get a Pope, educating others on SV, uniting all traditional clerics as some unified body who may be able to elect one of their own? What if any or all the above should be avoided and why? Should we all merely sanctify ourselves to the best of our ability (I know that it is God the ultimately sanctifies us) and leave the rest to God? Is this true both of the lay-people and clergy?
What if all the traditional Bishops including the SSPX got together and elected someone. Would you accept or reject such a man? Why or why not? Would you wait to see what he did first? Would it depend on who it was?
