Those whom we Catholics pray for as our "separated brethren" face a dilemma, given that we and they agree on most of the canon, and it's this: given that the bishops of the early church in council discerned the definitive list of biblical books for the Old and New Testaments, how does it make sense to take their word on most of the canon and then quibble about seven books on the OT list?
The protestant position would seem to imply that God was on a coffee break when that part of the canon was approved.
Actually, the early church in council did not officially pronounce on the canon as an article of faith. The first promulgation of the Roman Catholic canon as a dogma came at the Council of Trent in 1542, as the Catholic Encyclopedia states:
The Tridentine decrees ... was the first infallible and effectually promulgated pronouncement on the Canon, addressed to the Church Universal.In fact, until the Counter-Reformation there was always a strong "minority report" within the church on the extent of the Old Testament canon, holding that only those books contained in the Hebrew Bible should be taken as canonical. This position was taken, among others, by Origen, Athanasius, Hilary of Poitiers, and Jerome. Regrettably, this freedom of conscience was removed when the Council of Trent decided to make the "majority report" de fide.
As a scholar, I'm sometimes sorry that Protestants aren't more familiar with the Apocryphal or Deuterocanonical books. These books could be fruitfully employed for teaching about the "inter-testamental" period that provides such rich background for the New Testament, and which lay Protestants (yes, and lay Catholics, despite their canon) seem to know very little about.
On the other hand, I don't regret the loss of the Apocrypha as Scripture. It would be tiresome to be forced to take seriously the bourgeois ramblings of Ecclesiasticus as the Word of God, and it would be painful, if occasionally amusing, to watch inerrantists try to rescue the historicity of the book of Judith. On the whole, I think the Reformation got this decision right.
