Another Council of Carthage in 419 offered the same list of
canonical books.
Since the Catholic Church does not define truths unless errors
abound on the matter,  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 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.
