No, I don't "admit" such at all.
It is a construct.
It is not explicitly stated overtly and brazenly, specifically in Scripture.
The essence of the construct is in Scripture, as I've outlined above.
imho, there's tons more evidence for some flavor of Scripture alone (with Holy Spirit the Author) as our script, manual, superior authority . . . than there is for a long list of
extrapolated, inferred, created-out-of-whole-cloth presumptions, assumptions, TRADITIONS and doctrines of man or worse in the Romanist model.
Of course, I really don't expect folks wedded to the notion of safety, security, comfort etc. in a man-made edifice of such lengthy traditions . . . to see such facts short of a miraculous intervention of Holy Spirit . . . and, He is rather loathe to force things on people, typically. They have to seek God's face for most revelations of a life changing nature, in my experience.
Where did you outline it? In some particular post? I don't see a post where you outlined the essence of the derivation of "sola scriptura" from Scripture.

Where is it? Where are all these "tons [of] evidence"? Which verses?
