When talking with a Catholic friend (I'm a Protestant) about the apocrypha/deuterocanonical books, it occurred to me that a possible argument for their inclusion in the Canon would be their authority, measured in two ways:
- Claiming to be speaking on behalf of God (e.g "Thus saith the Lord...")
- Being quoted by other books considered to be a part of the Canon
Thus, I was wondering which (if any) books are quoted or referenced in the New Testament?
Also, are there any OT books that quote the apocrypha? (I have a feeling this may be a stupid question since, if I understand correctly, they were mostly written before the apocrypha.)
