So if they elect their own Pope who denies EENS are they then schismatics?
So, if they allow priests to vote, we'll have Pope Pivarunas I ... or Hadrian the VIII, if the CRMI can dust off Schuckhard's old Hadrian VII outfit.
Problem there of course is that, per Totalistm, I'd have to declare Papa Pivarunas to be a manifest heretic who's outside the Church and therefore that he had fallen from the papacy, since the CMRI deny EENS dogma, having twice published an article entitled "The Salvation of Those Outside the Church."
