Much of Catholic Mariology is derived from Sacred Tradition and rpedates Scripture. The idea that all revealed truth is to be found in "66 books" is not only not in Scripture, it is contradicted by Scripture (1 Corinthians 11:2, 2 Thessalonians 2:15, 2 Thessalonians 3:6, 1 Timothy 3:15, 2 Peter 1:20-21, 2 Peter 3:16).
Sola Scriptura or the notion that all of the Revealed Word is contained in the Torah is a concept unheard of in the Old Testament, where the authority of those who sat on the Chair of Moses (Matthew 23:2-3) existed. For over 400 years, there was no defined canon of "Sacred Scripture" aside from that same Old Testament; there was no "New Testament"; there was only Tradition and non-canonical books and letters. Scripture was defined from the many competing books by the very Tradition and Apostolic Succession denied by Protestants as being non-Biblical.
I believe the obligatory "crickets chirping" is in order, as, for some reason, there have been no comments in response.
