The supreme universal bishop acting like a dictator? Incredible. I kind of bet a lot of these same people were begging Pope Benedict to be less collegial, or at least would have cheered him on if he were.
The point they are trying to make is that the pope is not a dictator. He does have limits to his power. There are procedures and processes in place to help the church run as to avoid a dictator state that has now taken over Rome. This has been done because Pope Francis bypasses all rules, regulations and precedure and just does what he wants. The church is in a mess right now because of this.
If it's really so "illegal", why doesn't anyone put a stop to it?
Because many of the clergy in Rome are in league with the pope. The worst of modernists are in Rome. Orthodox clerics are beings purged. The last one of prominence is Cardinal Sarah as prefect of the congreagtion of Divine Worship and Discipline of the Sacraments. Even his congreagtion has been subverted by papal appointees who are modernists. In fact his deputy effectively runs the congregation in order to subvert the orthodox Cardinal Sarah.
Those in Rome have no reason to put a stop to it as they are in agreement with the direction of the current pontificate. In fact it’s the very reason they elected Pope Francis. The modernists got their man. The St Gallen group openly boasted about this.
Then there is the issue of other bishops who are orthodox being too scared to speak up for fear of being fired. Many simply lack the faith needed to openly oppose the pope and those around him.
So in short, those nearest to the pope do not want to put a stop to this and those that should speak up are too scared to. The case of Father Weinandy, Gallat, Cardinal Muller and the priests of the Congregation for the Dovtrine of Faith and other clergy are testament to what happens to those who speak up against the pope. You get fired or excommunicated or both.
Father Weinandy accurately claimed the main reason why God would permit this is to expose the lack of faith amongst the Episcopate and clergy in the church. Very few are brave enough to speak up. Secondarily I would say is to expose the uncatholic papal adulation present amongst many in the church. The fathers and Vatican I would watch in horror at some of the excesses of ultramontanism present amongst some laity and clergy. In fact Cardinal Newman warned about such a situation due to the proclamation of Papal Infalibility as he was worried many would incorrectly understand the dogma, which has happened.
