There are limits to his authority. He abuses his power when he exceeds these limits--as he would if he acted unjustly.

I understand perfectly well the supreme theory you've offered.  :-)    Here's where you lost me though:  my question was specific, and your answer was not.  Care to clarify with specifics?

The "supreme theory" is not mine. Please read the article on Ecclesiastical Abuse of Power which I have posted. This is the considered opinion of all the best theologians in the Church from time immemorial. The reason the pope's authority is not supreme is that he must, above all, obey the Divine Law which comes from God and on which Church law is based. That is to say, he must act justly in his dealings with others.
