I am on topic. I just read that Roman Catolics can’t agree on what they are being taught.
Your questions and "discoveries" only accentuate your ignorance of the Church. Actually, if you read my earlier postings you will see that there are two Magisteriums; the infallible Sacred Magisterium and the non-infallible Ordinary Magisterium. Your discussion is centered around the Sacred Magiserium, whose proclamations are issued under the authority of the Pope. Because there is only one pope all his proclamations are unanimous.
Peace to you
