You appraisal of the abundantly substantiated article (http://peacebyjesus.witnesstoday.org/Ancients_on_Scripture.html#2) is not unexpected due to your need. Do you really want to contend that the Council of Trent did not provide the first infallible and effectually promulgated pronouncement on the Canon, addressed to the church universal, which definitively settled the matter of the Old Testament Canon?
Trent merely ratified what had been effectively promulgated in Hippo and Carthage. The fact that the Church used these canons for the next 1100 years provides indisputable evidence notwithstanding the flawed anonymous article you referenced on a biased site.
The Inclusion of the books in the Hebrew Bible was settled 1100 years before Luther needed a change to justify his fanciful theories. Most objective historians, even the anti-Catholic secular humanistic ones, agree to this fact.
Suggest you focus on objective history and excise the fiction, accepting objective historical reality even when it contradicts your cherished opinions. The wording used by your site was careless in its choice of terminology and lacks the precision demanded in any instructional session. Be careful when copying from these sources as they lack the intellectual rigor to use precise terminology.
