The Pope Declares Himself To Be Infallible
“The Roman Pontiff, head of the college of bishops, enjoys this infallibility in virtue of his office, when, as Supreme Pastor and teacher of all the faithful–who confirms his brethren in the faith–he proclaims by a definitive act a doctrine pertaining to faith or morals….The infallibility promised to the Church is also present in the body of bishops when, together with Peter’s successor, ‘they exercise the supreme Magisterium,’ above all in an Ecumenical Council.
When the Church through its supreme Magistrium proposes a doctrine ‘for belief as being divinely revealed,’ and as the teaching of Christ, the definitions ‘must be adhered to with the obedience of faith.’ This infallibility extends as far as the doposit of divine revelation itself.”
Catechism of the Catholic Church, #891, 1994 edition.
“The Pope takes the place of Jesus Christ on earth…by divine right the Pope has supreme and full power in faith, in morals over each and every pastor and his flock. He is the true vicar, the head of the entire church, the father and teacher of all Christians. He is the infallible ruler, the founder of dogmas, the author of and the judge of councils; the universal ruler of truth, the arbiter of the world, the supreme judge of heaven and earth, the judge of all, being judged by no one, God himself on earth.”
Quoted in the New York Catechism.
“The Pope’s authority is unlimited, incalculable; it can strike, as Innocent III says, wherever sin is; it can punish every one; it allows no appeal and is itself Sovereign Caprice; for the Pope carries, according to the expression of Boniface VIII, all rights in the Shrine of his breast. As he has now become infallible, he can by the use of the little word, “orbi,” (which means that he turns himself round to the whole Church) make every rule, every doctrine, every demand, into a certain and incontestable article of Faith. No right can stand against him, no personal or corporate liberty; or as the [Roman Catholic] Canonists put it—“The tribunal of God and of the pope is one and the same.” -Ignaz von Dollinger,
