The book that many of your provided quotes are from is from Johann Joseph Ignaz von Döllinger's The Pope and the Council, which was an attack on the Papacy and Vatican I.
As a reminder, Döllinger was excommunicated because of his intransigent opposition to Vatican I and it's definition of Papal Infallibility.
If you had even a shred of intellectual honesty, or even basic Catholic sense, you would looked at your sources before taking them as Gospel and using them in this manner.
If anyone wants to see the kinds of sources LeDeg is using to bolster his argument, you can check out Döllinger's book here: https://archive.org/details/popecouncil00dl/page/n3/mode/2up
