“Respectfully, that was the Lord questioning the religious leaders. We should not be so arrogant as to believe that we have the same genius as our Lord when interpreting the very scripture inspired by Him.”
He argued the same way against the Sadducees. The Apostles argue the same way in the New Testament. Believers, such as Stephen, argue from the scriptures. They point to the scripture and teach from there. They do not point to Rabbanical decrees at any time. And if a genius is required to read the scripture, why is it that Jesus asks them to read the scripture that they can’t possibly understand with their own wisdom?
In fact, to my knowledge, every_single_instance of departure is a rail AGAINST the traditions and decrees of the rabbis. Never (that I can think of) is there an instance of correction against the Word of God or the clear interpretation thereof. It is the 'added to and the taken away' that are always on point. And that is done, always, by tradition.
