What part of: "you are upset about the Holy Spirit picking men that are human," isn't clear?
Your not one of those quasi modalists that doesn't believe that the Holy Spirit isn't God are you?
Let me make it very clear for you: God is responsible for picking every single man that sat on the throne of Peter. the same God that pickled the worst Pope (Whoever you think it is this week) is the same God that guides the Catholic Church in all truth and has promised that the gates of Hell will not prevail against the Catholic Church.
I'm sure the drunkenness of some made them "pickled", but you can't blame God for that! ☺
Then your answer is that God failed the Roman Catholic Church by intentionally hand picking the DDDPs? I have a higher view of Him than you, apparently, because I tend to believe He would NEVER intend for men that failed HIS OWN QUALIFICATIONS for leaders within the church to be the HEAD of all the churches. Nope, depraved men were responsible for the depraved Popes sitting where they did. They allowed it because of their own greed and depravity. And they are ALL yours, the Reformers like the earliest believers would have never tolerated such!
You have to admit the propensity for Italian Popes elected not to mention four from the Medici family.
