Papal infallibility is completely misunderstood. When speaking ex cathedra the Pope will not speak in error on matters of faith and morals, it doesn't mean that the Pope himself is free from error or that he has any more faith or is any more moral than we are. Many evangelicals (though they seldom admit it) speak and act as if they to are inerrent when speaking about faith and morals.

Peter (and for purposes of this discussion it is irrelevant if he was Pope, as we can all agree he was an Apostle and wrote portions of the Bible) said the following about Holy Scripture and made particular mention of Paul's writings:
15: And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you;
16: As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.
2 Peter 3:15-16 (Quoted from the KJV so as to avoid any questions about this being a "Catholic" viewpoint)

Thanks wagglebee! So how do you know when a Pope is speaking ex cathedra and when he is not? Pyro7480 said it had to do with the formulation.

What is the ex cathedra formulation that must be followed?
