I've tried to limit the amount of time I waste responding to the complete incoherence of Stubborn's thinking. There's no way to engage in a rational discussion with him.
Unless you gain at least an elementary understanding of the most basic, most fundamental of Catholic truths and make them your own foundation, it is apparent that engaging with me is going to remain completely incoherent for you.
As it is, you sedes don't simply ignore those foundational truths, oh no, simply ignoring them will never work, the sedes must first claim them to be either inapplicable to this crisis or altogether heretical ideas - and those who hold to them to be heretics. After that, the sedes proceed to claim all sorts of their own truths - right down to concluding it a teaching of the Church that popes are not popes, which is their foundation.
There may be a quicker cure, but in my opinion, the quickest cure for sedewhateverism is to cease attempting to use any sources associated with the Catholic Church's teachings, opinions, speculations or ideas in attempts to vindicate sedeism. The prots used their knowledge of Scripture to lose the faith, the sedes use whatever of the Catholic Church's teachings, opinions, speculations or ideas to lose the faith. No matter the method, the end result is the same.
