But think, Catherine: at the time that Paul wrote 2 Timothy (approx. 63 AD), all of the NT hadn't even been committed to writing. That would include: 1 Peter, 1 Peter, Matthew, Hebrews, Jude, John (the Gospel) 1 John and 2 John (Epistles), and Revelation.

That's give-or-take a few: these timelines are apaproximate.

So all of the Canonical NT books after 2 Timothy--- were they extraneous? --- since, as you interpret it, the existent canon of Scripture at that time, was "complete" and "finished"?

And how is it that Peter and Paul both instructed the Churches to imitate them (their actions) and to hold onto what they taught (their words), both as preached (spoken tradition )and as written (books, letters and sermons)?

What you say is true-—NT canon wasn’t complete at that time. But remember, they were writing for posterity, and inspired by God. He knew what the final result would be.
