Certain cardinals, and certain members of the papal curia, are not going to resolve their differences with Pope Francis.  They maintain that they are right, Pope Francis is wrong, and the leader of cabal of four (Burke) has in fact put Francis on notice (through the press) that they will issue an "official" correction to the pope if he does not accede to their demands regarding Amoris Laetitia, which they all feel is "non-magisterial," anyway.  Under these circumstances, the four cardinals an perhaps others too should resign their cardinalates, for which there is a twentieth-century precedent.
