The problem is that a lot of Catholics do believe it and can’t make the distinction in their own consciences!
Huh? I’m afraid I don’t know what you’re talking about? I never said, nor do I claim, Catholics must obey the pope in everything. And I do understand the meaning of Ex Cathedra (but I’m not sure you do).
Perhaps you are another one of these Literalists who seem to be so numerous among the Catholics on FR, with their dour and judgmental criticisms giving our Faith a bad name more than any rantings about “ideas” ever could.
