Read the Catholic history from a Catholic source for yourself and get back to me with your findings:
I have previously read your own source and it contradicts your assertion that the Canon was still in the process of formation "till the 5th Century" and it proves my point that the Canon was not officially established for the Roman Church until the Council of Trent :
"The Tridentine decrees from which the above list is extracted was the first infallible and effectually promulgated pronouncement on the Canon, addressed to the Church Universal"It also indirectly proves that Hippo and Carthage contradict Trent on the Septuagint version of 1 Edras:
"...the first and second of Esdras (which latter is called Nehemias)"to which you have not yet given any response.
Cordially,
