But then you should not argue that the Bible says something, but that the Pope does. :-)

In principle, yes, but the Pope can't answer every question I have 24/7, so he and his assistants have prepared some literature for my perusal.

And it's not like what the constitution says or what the bible says is completely useless, it's just that when it comes to conflicting interpretations, you look to the courts or the church for guidance.

The Catholic church's official position is a bit more nuanced. The Pope can declare things infallibly under special circumstances, but they place great importance on ecumenical councils, too. (And in fact, to avoid circular logic, Papal infallibility was declared at one of these councils. They might be dogmatic, but they ain't stupid.)

Take everything I say with a grain of salt. Culturally, I grew up in the heartland of the Protestant Reformation where Luther himself went around and preached; and philosophically I veer between being a dirty atheist and a cowardly agnostic, depending on how I feel on the day.

I just treat the theological discussion like Lord of the Ring fans or Warhammer 40k would treat lore discussions.
