Since Christ didn't place a high value on the Sadducees' and Pharisees' opinions why should we determine that Rabbis have the scriptures correct?
2 Timothy 3:16-17 King James Version (KJV)
16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
17 That the man of God may be perfect, thoroughly furnished unto all good works.
Do you want any group making that decision for you?
There was never then and is not now any semblance of consensus among rabbis. Anyone can cherry pick a quote that agrees with their premise, if they are not too scrupulous, even among the ancient sources.
