The Bible was not around the early days, but the gospels and
epistles were already written and circulated widely. It is not the
case of "no books (bible) and all talk (tradition)".
Tradition is not all talk it considers the written work of the
Apostles as well as the early church fathers as part of itself. e.g
Paul's verse about teaching being handed down orally or by letter.
(2 Thess. 2:15)
The epistles would come under the written tradition handed down,
till the Bible was produced. The Bible then would inspire Tradition
e.g Augustine's writing based on the Pslams,etc.
In this both Scripture and Tradition comes together.
Sola Scriptura before the canonization is a
misconception.
Could you explain this a bit further?
