Okay, after reading a little about that time period, I remember learning it was a time of truly, and really great political strife. Just did not recall that name Cadever.
The way the nuns explained to us students a long time ago, I remember learning this time period God allowed to prove that His Church was a Divine Institution, not human, because if it was human, during all these things that happened it would have fallen and the gates of Hell would have prevailed. Although many abuses happened and strange things like digging up the dead to put them on trial, Popes being strangled, etc. The doctrines of the Church were not tampered with successfully, such as today with Vatican II. In fact they were protected, unlike today. That is the difference.
Whether the Holy Ghost actually picks the person of Pope, as He did St. Peter. I don't know but I will ask Him when I face Him face to face.(interesting question)
I do know that the Holy Ghost is invoked often, i.e. in the Divine Office by the Hour of Tierce. In fact the entire liturgy of the Church gives us the example of continual recourse to the Holy Ghost. Many functions of Holy Church opens with an invocation to the Holy Ghost. So when you have holy men getting ready to elect a True Pope, I do believe the Holy Ghost would be invited.
However when Vatican II became full swing, unless you do not believe the Vatican was infiltrated with the enemy. If you close your eyes to the fact that Protestants were there along with other enemies of the Church to make it more worldly, if you turn your head so as not to notice the INTENT of these Freemasons, communists who now had control, of the property of the Church, do you really believe the Holy Ghost was there to help. I don't. God is not mocked.
