And exactly how could you possibly determine that and somehow know you're correct? And frankly there really isn't anything as far as teachings are concerned in the Apocrypha that isn't found in the 66, with only the exception of praying for the dead, which we do know was done not only in the early Church but also within at least some circles in Judaism.
At our Catholic church we do all of the above plus some. We have the daily readings as mass, the strong encouragement to read scripture on our own, and I'm currently involved in a 25 week study of Matthew's gospel at the church. Last year I was involved in two other studies at the church.
Your Catholic church is unusual. Locally, I attended a Catholic church's men's study, that began with an apology, "This is the first time we've hit Bible study in ten years as a church". Regardless, I understand the de-emphasis on Bible study in Rome is a) historical--killing and persecuting people for putting the Bible in the vernacular and b) modern--the Bible study couldn't be good if the doctrine is heretical and different than every other one of thousands of sects that emphasize Bible study (it's illogical and requires that ALL OTHER CHRISTIAN GROUPS are demonically deceived if Rome is the only right one for doctrine).
How can I determine the apocrypha is off?
1) Aren't accepted by the Jewish people
2) Aren't accepted by more than 99% of groups that began new church movements, via Bible study and study of non-canon books
3) Do not say, as the Bible says over 6,000 times in the OT alone, "This is the Word of God", indeed, they say things like "Here's wisdom my grandfather told me"
4) Contain teachings that contradict the Bible
5) Contain impious or "dirty" passages that are more sexual or violent in nature than the Bible
6) Were reluctantly placed in some movements to keep the peace, while adding footnotes like "of unknown origin/veracity"
7) Contain self-contradictory teachings, like Person A disagrees with Person B in the same apocrypha
8) Shows lack of character: Daniel tricking people instead of being an honest witness, the child Jesus puts a fellow child to death, etc.
9) Do not withstand any type of codes/gematria analysis
But all that is overcome because Rome's tradition trumps all...
