Whether this council existed or not you said that scripture was based on the Hebrew Bible for the most part.
Even if they were local councils they all believed the same thing vis a vis scripture, i.e., Tradition states that these books were indeed scriptural, moreover, the Council of Carthage of 419 was implicitly accepted during the 7th ecumenical council and at Florence (the Orthodox also accept these books as scriptural). Also, please show me any council that suggests that the mind of the Church had changed concerning these books or better yet find me a bible prior to the Reformation that doesn’t have these books in them, i.e., citing a few Catholics that disagreed with the Canon is no less realistic than citing a recalcitrant bishop of today that differs on doctrines/Tradition already long held by the Church.
Yes, they may have questioned them like others have questioned other Traditions, however, they knew the mind of the Church was already established in this respect, and accepted the decisions that were made.
Forgive me, but you mentioned the Hebrew Bible when we first spoke about accepting the deuterocanonical books, moreover, Tradition was such that the deuterocanonical books were considered divinely inspired. Protestants are not holding any view considered remotely Catholic or Orthodox (Jerome, Cajetan, and Erasmus died as Catholics, i.e., they accepted the Church’s teachings (Jerome wrote the Latin vulgate which included the deuterocanoncal books as scriptural not apocrypha, and last I checked Cajetan and Erasmus were Catholics in good standing, i.e., they accepted church teaching).
