I suspect sociology rather than theology explains the dissidents, who are firmly hierarchist and who see any hint of either free thinking or-egalitarianism as alien to the Church. The reality is that this bridge was crossed on the Tiber in the 1960s and the counter-revolutionary papacies of St. John Paul and Pope Emeritus Benedict will not undo it. The revolution was picked up by theologians when Rome abandoned it, but Rome has now come and joined it and brought the world's bishops with it. Only Francis could have elicited the truth of what was already happpening in parishes worldwide, regardless of doctrine. No one believed the old proof texting, even and especially by the counter-revolutionary Saint John Paul. An error repeated is still an error. There was simply no doctrine of mortal sin in Paul's time. Receiving unworthily was something else. Divorcing to marry another is obviously adultery, but marrying well after divorce is not the same thing. Loyalty is not faith afterall.
