RE: I never mentioned their belief in “ex cathedra”.
I was referring to this statement: “The Pope is never in error, regardless of subject matter.”
Papal infallibility (or speaking ex cathedra) does NOT mean the Pope is never in error regardless of subject matter.
Inerrancy as it refers to the Pope states that by virtue of the promise of Jesus to Peter, the Pope is preserved from the possibility of error “when, in the exercise of his office as shepherd and teacher of all Christians, in virtue of his supreme apostolic authority, he defines a doctrine concerning faith or morals to be held by the whole Church”.
A personal opinion by a Pope about economics does not apply and therefore is not necessarily infallible.
