Pope Innocent I, Letter to Exsuperius, Bishop of Toulouse 6, 7, 13
(405 AD)
"A short annotation shows what books are to be accepted as canonical. As
you wished to be informed specifically, they are as follows: The five books
of Moses, that is, Genesis, Exodus, Leviticus, Numbers, Deuteronomy; and
Jesus Nave, one of Judges, four of Kingdoms, and also Ruth, sixteen books
of Prophets, five books of Solomon, the Psalter. Likewise, of histories, one
book of Job, one book of Tobias, one of Esther, one of Judith, two of
Maccabees, two of Esdras, two books of Paralipomenon. Likewise, of the
New Testament: four books of Gospels, fourteen Epistles of Paul, three
Epistles of John, two Epistles of Peter, the Epistle of Jude, the Epistle of
James, the Acts of the Apostles, the Apocalypse of John. Others, however,
which were written under the name of Matthias or of James the Less, or
under the name of Peter and of John, by a certain Leucius–or under the
name of Andrew, by the philosophers Nexocharis and Leonidas–or under
the name of Thomas, and such others as may be, are not only to be
repudiated, but, as you know, are also to be condemned."
This list of the Canon has not changed ever since then , but has been confirmed over and over again to this day.
The Bible is a Tradition of the Catholic Church.
