However, wasn’t the Council of Carthage a regional, not a ecumenical council? The same would go for the Council of Hippo. Also is not the canon of those councils different than that from Trent in that the earlier councils included 1 Esdras and 2 Esdras, which due to splitting 2 Esdras into two books, would gave required Trent to accept 3 Esdras to conform with the earlier councils?
The list of Canon from Trent are the same from Council of Carthage and Hippo.
Melito, bishop of Sardis, an ancient city of Asia Minor (see Rev 3), c. 170 AD produced the first known Christian attempt at an Old Testament canon. His list maintains the Septuagint order of books but contains only the Old Testament protocanonicals minus the Book of Esther.
The Council of Laodicea, c. 360, produced a list of books similar to today’s canon. This was one of the Church’s earliest decisions on a canon.
Pope Damasus, 366-384, in his Decree, listed the books of today’s canon.
The Council of Rome, 382, was the forum which prompted Pope Damasus’ Decree.
Bishop Exuperius of Toulouse wrote to Pope Innocent I in 405 requesting a list of canonical books. Pope Innocent listed the present canon.
The Council of Hippo, a local north Africa council of bishops created the list of the Old and New Testament books in 393 which is the same as the Roman Catholic list today.
The Council of Carthage, a local north Africa council of bishops created the same list of canonical books in 397. This is the council which many Protestant and Evangelical Christians take as the authority for the New Testament canon of books. The Old Testament canon from the same council is identical to Roman Catholic canon today. Another Council of Carthage in 419 offered the same list of canonical books.
Since the Roman Catholic Church does not define truths unless errors abound on the matter, Roman Catholic Christians look to the Council of Florence, an ecumenical council in 1441 for the first definitive list of canonical books.
The final infallible definition of canonical books for Roman Catholic Christians came from the Council of Trent in 1556 in the face of the errors of the Reformers who rejected seven Old Testament books from the canon of scripture to that time.
There was no canon of scripture in the early Church; there was no Bible. The Bible is the book of the Church; she is not the Church of the Bible. It was the Church–her leadership, faithful people–guided by the authority of the Spirit of Truth which discovered the books inspired by God in their writing. The Church did not create the canon; she discerned the canon. Fixed canons of the Old and New Testaments, hence the Bible, were not known much before the end of the 2nd and early 3rd century.
Catholic Christians together with Protestant and Evangelical Christians hold the same canon of the New Testament, 27 books, all having been originally written in the Greek language.
Catholic Christians accept the longer Old Testament canon, 46 books, from the Greek Septuagint (LXX) translation of the Alexandrian Canon.
Protestant and Evangelical Christians, from the Reformers onward, accept the shorter Old Testament canon, 39 books, from the Hebrew Palestinian Canon. Jews have the same canon as Protestants.
Canonical books are those books which have been acknowledged as belonging to the list of books the Church considers to be inspired and to contain a rule of faith and morals. Some criteria used to determine canonicity were
special relation to God, i.e., inspiration;
apostolic origin;
used in Church services, i.e., used by the community of believers guided by the Holy Spirit.
Other terms for canonical books should be distinguished: the protocanonical books, deuterocanonical books, and the apocryphal books.
The protocanonical (from the Greek proto meaning first) books are those books of the Bible that were admitted into the canon of the Bible with little or no debate (e.g., the Pentateuch of the Old Testament and the Gospels)
The deuterocanonical (from the Greek deutero meaning second) books are those books of the Bible that were under discussion for a while until doubts about their canonicity were resolved (e.g. Sirach and Baruch of the Old Testament, and the Johannine epistles of the New Testament).
