>> And many Early Church Fathers said the deuterocanonicals were not read for doctrine, <<
A very subtle, but key misquote: it’s not that aren’t read *for* doctrine, but that they aren’t read to *prove* doctrine. In most cases when something similar to that is said, the context is an attempt to convert Jews. Since the Jews didn’t hold them as canonical (as of some time AFTER Jesus’ resurrection), the Fathers reckoned it’s no point using them as proof of Christian doctrine. The fact that they are approved to be read in church, however, means that they are to be read for doctrine, since church readings and the subsequent homilies were the typical means of Christian indoctrination; most of what we know of most of the Church fathers comes from homilies.
(I know “homily” is a term used by Catholics for the instruction which comes after the readings, similar to, but more specific than a sermon.)
this is interesting..
"Here we close our commentaries on the historical books of the Old Testament. For the rest (that is, Judith, Tobit, and the books of Maccabees) are counted by St. Jerome out of the canonical books, and are placed amongst the apocrypha, along with Wisdom and Ecciesiasticus, as is plain from the Protogus Galeatus. Nor be thou disturbed, like a raw scholar, if thou shouldest find anywhere, either in the sacred councils or the sacred doctors, these books reckoned as canonical. For the words as well of councils as of doctors are to be reduced to the correction of Jerome. Now, according to his judgment, in the epistle to the bishops Chromatius and Heliodorus, these books (and any other like books in the canon of the Bible) are not canonical, that is, not in the nature of a rule for confirming matters of faith. Yet, they may be called canonical, that is, in the nature of a rule for the edification of the faithful, as being received and authorised in the canon of the Bible for that purpose. By the help of this distinction thou mayest see thy way clearly through that which Augustine says, and what is written in the provincial council of Carthage."
