The authority of his office MY FOOT.
The Pope of Rome has NO AUTHORITY to change the deposit of the faith. Period. Full stop. Any Catholic who thinks he does is severely misinformed and ought to read up on Honorius I.
Liberal masquerade as for the common man, and they are the ones who, having procured an office, seek to expand its autocratic power beyond all reason.
The Pope has one job: to protect the revelation passed down by Christ to the Apostles. If he fails at that, he needs to be removed.
What if he speaks "ex cathedra"?
