The Council of Carthage seems to have dealt effectively with the Marcel LeFebvre schismatics by excommunicating the lot of them and not just the ring leaders.
Likewise, the Council of Laodicea was no comfort to SSPXers or SSPVers or Feeneyites.
BTW, I pointed out to you the promise of Jesus Christ to be with His Church (not some perpetually aggrieved little cult of sede vacante schismatics) until the end of the world. That was your answer.
Do we have Scriptural evidence that Simon bar Jonah who became Peter was ever baptized or any apostle? Things that make you go HMMMMMM!
I was around for Pope Saint John Paul II and I was very favorably impressed. I could not name three participants in II Council of Constantinople nor in the Council of Carthage, nor in the Council of Laodicea. Nor have I any familiarity whatsoever with even one document emanating from any one of them. Somehow life goes on.
To make believe that post-Vatican II popes John Paul I, Pope Saint John Paul II, and Benedict XVI or EVEN Frankie were not popes is to be a sede vacantist rather than a Catholic. Frankie has proven to be an idiot but he is still pope until he resigns or God fires him in the traditional manner.
Well if you were impressed! To heck with that pre-Vatican II era which completely contradicts the post-Vatican II era! Ignorance truly is bliss.
