No doubt you ignored the main point ... your assertion that the council in 397 was the first to publish a list of the canonical books has been falsified.
Are you referring to the following from your source?
The first historical reference listing the exact 27 writings in the orthodox New Testament is in the Easter Letter of Athanasius in 367 AD. His reference states that these are the only recognized writings to be read in a church service. The first time a church council ruled on the list of "inspired" writings allowed to be read in church was at the Synod of Hippo in 393 AD. No document survived from this council - we only know of this decision because it was referenced at the third Synod of Carthage in 397 AD.
