1) The Pope can't teach pernicious error to the whole Church. That's what the Church teaches, pal.
2) Yes, everything the Church teaches us IS infallibly safe to believe.
3) This is what Catholics believe, Stubborn.  

1) No, that is not what the Church teaches, that is only what certain 19th/20th century theologians have taught which people wrongfully accept as though their teachings are de fide teachings of the Church. I posted below what the Church does teach.
2) Certainly true, but the pope is not the Church.
3) Yes, Canon George Smith is spot on and explains what the Church teaches very simply and very clearly.



You will find the Church teaches the only time the pope is infallibly protected from teaching even the possibility of error, is decreed at the First Vatican Council.  In short, he is only divinely protected when he defines a doctrine ex cathedra.

This is the dogma:

"We teach and define as a divinely revealed dogma that when the Roman pontiff speaks ex cathedra, that is, when...he defines a doctrine concerning faith or morals to be held by the whole church, he possesses, by the divine assistance promised to him in blessed Peter, that infallibility which the divine Redeemer willed his church to enjoy in defining doctrine concerning faith or morals. Therefore, such definitions of the Roman pontiff are of themselves, and not by the consent of the church, irreformable".


In the same council, you will also find when he is *not* divinely protected in his teaching office, namely, whenever he teaches "some new doctrine", which is to say, whenever he teaches heresy.

"For the holy Spirit was promised to the successors of Peter not so that they might, by his revelation, make known some new doctrine, but that, by his assistance, they might religiously guard and faithfully expound the revelation or deposit of faith transmitted by the apostles".


Now I just posted what the Church teaches for you. Understand that the above teaching is dogma, it is binding on all Catholics under pain of mortal sin. It is complete, it is not lacking or missing anything, the Holy Ghost did not leave us with an incomplete dogma. We are not permitted to change or to add anything to it under the pretext of a more profound understanding of it - which is exactly what those 19th/20th century theologians have done which led multitudes to have a false understanding of the Church's infallibility.

Note that the same Council warns: "Hence, too, that meaning of the sacred dogmas is ever to be maintained which has once been declared by holy mother church, and there must never be any abandonment of this sense under the pretext or in the name of a more profound understanding".
