Pope Francis indeed has the Keys to the Kingdom and the ex cathedra privileges if he so chooses.
The Catholic Church comes from Christ>St. Peter and the Apostles> and through apostolic succession after that.
A long line of Popes, some of them brilliant, some of them not so good.
They are not impeccable, but when they speak on faith and morals they are infallible.
So am I, when I quote the bible...And I don't need a special chair to do it...
What fallible commands have your popes given outside of the scriptures over the Centuries???
