Sigh The superpopes are at it again.
The following Envoy article should help: 5 Myths about 7 Books
It is specifically myth 5 quoted here.
The early Church Fathers, such as St. Athanasius and St. Jerome (who translated the official Bible of the Catholic Church), rejected the deuterocanonical books as Scripture, and the Catholic Church added these books to the canon at the Council of Trent.
First, no Church Father is infallible. That charism is reserved uniquely to the pope, in an extraordinary sense and, in an ordinary sense, corporately to all the lawful bishops of the Catholic Church who are in full communion with the pope and are teaching definitively in an ecumenical council. Second, our understanding of doctrine develops. This means that doctrines which may not have been clearly defined sometimes get defined. A classic example of this is the doctrine of the Trinity, which wasn’t defined until A.D. 325 at the Council of Nicaea, nearly 300 years after Christ’s earthly ministry. In the intervening time, we can find a few Fathers writing before Nicaea who, in good faith, expressed theories about the nature of the Godhead that were rendered inadequate after Nicaea’s definition. This doesn’t make them heretics. It just means that Michael Jordan misses layups once in awhile. Likewise, the canon of Scripture, though it more or less assumed its present shape - which included the deuterocanonical books - by about A.D. 380, nonetheless wasn’t dogmatically defined by the Church for another thousand years. In that thousand years, it was quite on the cards for believers to have some flexibility in how they regarded the canon. And this applies to the handful of Church Fathers and theologians who expressed reservations about the deuterocanon. Their private opinions about the deuterocanon were just that: private opinions.
And finally, this myth begins to disintegrate when you point out that the overwhelming majority of Church Fathers and other early Christian writers regarded the deuterocanonical books as having exactly the same inspired, scriptural status as the other Old Testament books. Just a few examples of this acceptance can be found in the Didache, The Epistle of Barnabas, the Council of Rome, the Council of Hippo, the Third Council of Carthage, the African Code, the Apostolic Constitutions, and the writings of Pope St. Clement I (Epistle to the Corinthians), St. Polycarp of Smyrna, St. Irenaeus of Lyons, St. Hippolytus, St. Cyprian of Carthage, Pope St. Damasus I, St. Augustine, and Pope St. Innocent I.
But last and most interesting of all in this stellar lineup is a certain Father already mentioned: St. Jerome. In his later years St. Jerome did indeed accept the Deuterocanonical books of the Bible. In fact, he wound up strenuously defending their status as inspired Scripture, writing, “What sin have I committed if I followed the judgment of the churches? But he who brings charges against me for relating the objections that the Hebrews are wont to raise against the story of Susanna, the Son of the Three Children, and the story of Bel and the Dragon, which are not found in the Hebrew volume (ie. canon), proves that he is just a foolish sycophant. For I wasn’t relating my own personal views, but rather the remarks that they [the Jews] are wont to make against us” (Against Rufinus 11:33 [A.D. 402]). In earlier correspondence with Pope Damasus, Jerome did not call the deuterocanonical books unscriptural, he simply said that Jews he knew did not regard them as canonical. But for himself, he acknowledged the authority of the Church in defining the canon. When Pope Damasus and the Councils of Carthage and Hippo included the deuterocanon in Scripture, that was good enough for St. Jerome. He “followed the judgment of the churches.”
