True, but if the Church never accepts it than it won’t matter much in the end. The Church’s doctrine will stay pure. People never really do.
“Perhaps not ... but all it will take is one appearance of Mary declaring otherwise, one divine revelation to a pope, or one translation of a long lost apostolic father to change that.”
Nope. No such apparition of Mary will ever happen, nor will there be a papal declaration, nor a translation of a non-existant apostolic document. It’s never happened yet, and it can’t anyway.
Guadalupe
La Salette
Fatima
Lourdes
... etc. etc. etc.
Perhaps you haven't been involved in Romanism very long. Consult Dr. Google, you will probably find a dozen more.
