Who is correct? That's for you, Dear Reader, to decide.
In the first message, I asked Rob Vanhoff is he agreed Stern's statement about a necessary oral tradition. Stern wrote:
"The common Christian idea that Judaism became 'degenerate' because human tradition was added to God's Law is mistaken. The five books of Moses have rightly been called the constitution of the Jewish nation, but a nation needs more than a constitution. There could never have been a time when tradition of some sort was not a necessary adjunct to the written Torah -- for the written Torah simply does not contain all the laws and customs needed to run a nation.
For this there is evidence even in the Pentateuch. Moses wrote in Deuteronomy 12:21 that the people of Israel could slaughter animals 'as I have commanded you,' but no commands concerning how to slaughter are found anywhere in the written Torah. Something external is implied--legislation, tradition, an oral Torah. God could announce his will from heaven whenever uncertainty arises, but this not his normal means of guidance either in the Old Testament or in the New. Nothing in the Bible suggests that God opposes accumulating knowledge and experience or creating guidelines and rules," pg. 148 of Messianic Jewish Manifesto by David Stern
On the Torah Resource blog (http://torahresourceblog.com/is-there-a-core-oral-torah/), Vanhoff responded:
Is there a core “Oral Torah”?
