So ... it appears that the question comes down to ... what has truly been revealed by God ... and what has not ?

Yes, for every religious question, is this not so?

Catholics claim a fuller revelation, partly based upon that which is not found in the scriptures, ... while Protestants claim a more restricted revelation ... limited to what is found in the scriptures.

Well, yes. Since you say "claim."

I would argue that the Protestant tradition of Biblical interpretation, including the very idea of sola scriptura is itself extra-Biblical.

And , the Catholic interpretation, the understanding of Scripture is a part of what was revealed, along with the words themselves.

Jesus didn't seem to think so ...

John 5:39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.

And, the Catholic interpretation, the understanding of Scripture is a part of what was revealed, along with the words themselves.

Even if the words aren't there ?
