I am grateful for every person God used historically - including Jews, through whom we have 2/3 all the books of Scripture, because unto them were committed the oracles of God. And so many of the best doctors were Jews; don't ask me why.

“through whom we have 2/3 all the books of Scripture, because unto them were committed the oracles of God.”

Likely true, but there are some unknowns:

Who wrote Ruth? She was not a Jew. Did she write it?
Who wrote Job? His life came before the Jewish nation (I think).
Who wrote Luke & Acts? Tradition often says he was a Gentile. Was he?

More to my point, the Hebrew Scriptures were written before the early church came into existence.
