Thank you Cassini for taking the time to write this. The neo-platonic infiltration in the renaissance Church has never really been properly expunged and whilst the Church is perfect for saving individual souls, when it comes to saving entire societies, it doesn't have the rock solid certainties that it had in the middle ages. Whilst the harrassment of pilgrims to the Holy Land led to the crusades, Pius VI and VII (Yes those two again) were very luckluster in condemning the French Revolution. Pius VII even travelled to Paris to Napoleon's coronation where Napoleon in fact crowned himself.
Consalvi was sent by Pius VII to negociate the concordat with Napoleon and unfortunately he conceded on so much that Napoleon considered the Concordat a victory. Consalvi even attended the reception of Napoleon's adulterous second mariage
This is one of the paintings to represent the victory of Napoleon over the Church. Thats a very sheepish looking pope on the left of the obelisk with Napoleon (like lucifer)bringing the light of the revolution to mankind.

It's very difficult to imagine the medieval popes handling the situation in the same way. When you condede geocentrism, it's not a big move to concede on the rest.
