Of course I realize he’s Jewish.
That’s what enabled him to deal with the Hebrew in Genesis so well.
How is his rejection of Jesus as the Messiah relevant to his ability to interpret Genesis?
Are you asking us to take him as an authority only when he agrees with you? If Jesus came in fulfillment of the Scriptures, which I am sure that we both agree to be true, those same Scriptures were written in the same Hebrew you claim he has special insight into. Can't you see your circular logic?
