Some where you have lost your ability to think rationally it appears. No one can give you the “proof” you seem to need on a forum like this and you seem to not have the good will to seek the truth yourself. But if I am mistaken about you, I suggest you start with a reading of the documents from the Ecumenical Councils of the Church for the continuity of Dogma. Remembering that Vatican II was a restatement and development of doctrine in more understandable modern language. Then read Cardinal Newman on the development of dogma.
Good start I think. Other Catholics can add other or better suggestions.
Good searching.
Rather, you made a huge claim.
I asked you to back that claim up with anything that would lead an objective person to think, "gee, maybe his big claim is correct."
You offered that if one theoretical person anywhere obeyed the church, it was proof of your huge claim.
I pointed out you failed to support your claim.
In fact, failed three times now.
Here's a good suggestion for you on that topic: Living Tradition (Viva Voce - Whatever We Say)
It's pretty difficult to defend both the "unanimous consent of the fathers" and the "development of doctrine" without exposing the blatant contradiction between them.
