Yes, the highest principle in the Church to sedes necessarily registers as being made up. Aren't you special!
I guess we'll never know where the phrase: "Excommunicated from the Church" comes from.
Your "highest principle," namely that Tradition is the proximate rule and interpreter of faith (something also promoted by that Drew character) is nothing more than a slight variation of Protestantism, the difference being that the Prots only have one source of Revelation (Scripture) and the Trad-Prots have two (Scripture and Tradition).
As with Scripture, the issue with Tradition is its interpretation and application, and there's only one authority permitted to interpret Tradition, the living Magisterium. As St. Thomas said, by rejecting the Magisterium as the proximate rule for interpretation, you effectively make yourself the rule. You replace the Magisterium with your own private judgment. If Stubborn decides something is Traditional, then it's Traditional. This effectively makes you your own doctrinal authority.
