That is the anti-Catholics saying that. And you are changing the subject. Sola Scriptura has resulted in so many "novelties", and now even though they follow the Bible, claims are made they are not christian. They are Sola Scriptura, and you (all) are stuck with them and the albatross of Sola Scriptura.
You were the one that brought it up.
I need not bother to respond, much further, other than to state that 'sola ecclesia' was not the way of the early Church.
When push came to shove, it was what the Holy Writ best supported, which then was then most widely accepted, then agreed upon to be adopted as doctrinal statement within the Church itself, as toward questions of which there were logical enough grounds of disagreement due to Scripture , saying various things in differing ways & contexts, etc.
There is no 'albatross' of sola scriptura.
It is one of the oldest principles in the book, and was much the way of the early Church.
It took long centuries to eventually depart from it.
We all know of complications and theological errors that has produced.
Leaving things to be, that as usual, you've got nothing much, in all your blustering assertions.
