One of the best things I have ever heard a pope teach came from St. John Paul II. He placed a limit on the pope’s supreme authority.
Thankfully, he said that he had no authority to change Catholics teaching in the Ordinary Magisterium of the Church! That was GREAT!
‘The pope is the perennial principle and foundation of the unity of the Church,’ Cardinal Müller writes in a new essay for First Things. ‘But the Church is not centralized in him, as if he were the supreme leader of a totalitarian party.’
