It is probably a problem for God as well. A small one though. From what I've read 100% of Catholic institutions are not 100% in agreement with 100% of what other Catholic agencies do 100% of the time. This suggests there is some disunity in the Catholic organization itself. As far as the title of this thread is "If no one is Pope, everyone is Pope" then I think the Bible teaches everyone should be convinced in their own mind. I am responsible for my soul the same as you are. God left us a Book to direct which direction to choose in life (along with the Holy Spirit). Peace be with you.
But I'm not sure how unanimity bears on the discussion. I don't look to the bishops in German for my "direction." My bishop (Richmond, VA) gets my attention and I run what he says by what the pope says.
But even then, While I listen respectfully when PapaFran talks about the environment, I am not docile there and have no duty to be docile in such things. I will, so to speak, check my work. I will consul with respected peers and "superiors." But PapaFran is not an environmental scientist and he himself admitted he's no economist.
I would say that in my experience, it's RARE that anyone says, "You HAVE to think this." The closest is people saying, "I think that you should be ASKING and wondering about this." So, yes, at every step, the decision is my responsibility.
It just this minute occurred to me that a lot of people, a lot of Catholics, want their religious life given to them like a pill from the pharmacy. It's hard to help such people, except to say that Jesus is the Truth, that means the Truth is a person, and the only way to get to know a person is in relationship. Answers won't do it.
