Only an extraordinarily saintly pope would have a prayer of reversing the obdurate disobedience of the leaders of the Conciliar Church. The current cardinals and bishops are largely products and messengers of a spirit of rebellion against the deposit of faith. Their mass conversion would be in the order of the miraculous, such as only some of the traditional saints have been instruments of.
Yes, a pope faithful to Catholicism could issue 25+ edicts such as I suggested, but he would also have to be prepared to encounter a hierarchy who disregarded him, even on pain of their excommunication -- because in many ways they excommunicated themselves already decades ago.
I believe that the people must *first* want to repent and do all that goes with that, otherwise, all God's giving us an extraordinarily saintly pope would do, is provoke even more hate and persecution against the Church and faithful.
Without the world's population resolve to repent, an extraordinarily saintly pope would have, not only the hierarchy, but literally the entire world's population vehemently against him, (minus a small fraction of the population, aka the faithful).
By and large, nobody on earth even believes there is any crisis at all, and those who see the problems, ignore them. We must remember that the people already have what they really want, that’s why they have it. That’s why they’ve chosen it, that’s why they protest and fight for it, and its why they continue to absorb it, cling to it and love it. Overall, they love this thing we call a crisis and will have no holy pope prodding their consciences under any circuмstances.
"Before man is life and death, good and evil, that which he shall choose shall be given him." Eccl 15:18
If, OTOH, we did end up with a holy pope who went about fixing this mess, as Our Lady at Fatima said, he would have much to suffer, Catholic people would be martyred and nations would be annihilated. Think Antifa, times a few million.
