As already said, it is the Pentateuch and the four NT biographies of Jesus that I have issues with on the basis of their own contents, format/style and claims.
As I already quoted yesterday:
The book of Luke even directly goes out of it's way to describe what the book matter of fact is:
Many have undertaken to draw up an account of the things that have been fulfilled among us, just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. With this in mind, since I myself have carefully investigated everything from the beginning, I too decided to write an orderly account for you, most excellent Theophilus, so that you may know the certainty of the things you have been taught.
(
Luke 1:1-4)
And as John ends:
This is the disciple who testifies to these things and who wrote them down. We know that his testimony is true. Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written.
(
John 21:24-25)
Two very basic examples of the books themselves giving self-definition. The four NT biographies of Jesus are 3rd person narratives recounted from oral tradition (as with much of the Apocrypha and so-called "gnostic" texts).
I think the Qur'an's own commonalities with certain infamous "Gnostic" texts (like the infancy gospel of Thomas for examples, which Christian apologists love getting sweaty over) help to prove my case, that the Qur'an speaks to a much wider discourse than the Bible canon of the Catholics/Protestants. Rather speaking of the direct revelation given to Jesus, distinguished from his life. By extension, the many streams of oral tradition that have filtered down through various forms of Pre-Christianity (including those included in the NT which are simply one compilation of a few select streams, Paulian and Johannine being the most prolific sect).
Torah is a far more complex and nuanced situation, as I've already said. I believe though that whatever Moses received on Mount Sinai was "Torah", but not the accounts of Moses reciving things on Mount Sinai. Do you get the distinction?
Islamically speaking; revelation (Qur'an) is not biography (Seerah). Hadith are not Qur'an either, but they are related, in the sense of Moses' relationship to the Torah.
Scholarship on what Jews have with the Pentateuch is very interesting though.
Anyway, I've tried the Baha'i view before and it just doesn't sit right and feels very intellectually dishonest to me. However I do respect your right to hold such a view.
