Aside from the impertinence of a Christian politician debating Judaism with a rabbi, one might also view Kasich’s opinion regarding the greater importance of Abraham over Moses as being mildly offensive in this context, because on reason a Christian may have for that view would be due to Abraham’s direct relationship to the covenant and prophesies that ultimately led to their fulfillment through the life and sacrifice of Jesus Christ.
While the story of Moses contains some allusions to this - through the symbolism of the Angel of Death passing over the home of those who displayed the blood of the lamb outside their door - there is no direct relationship to the coming of Christ through the story of Moses, as their is throughout the story of Abraham, not only in prophesy, but more importantly through the original covenant God gave to Abraham which formed the foundation of all events that would follow leading up to the forgiveness of sins through the Crucifixion of Christ.
Hence, Abraham is definitely the more important Old Testament figure from a Christian point of view - and therefore perhaps not a viewpoint that a Christian ought to be foisting upon a Jew.
Would it satisfy the Christians if you just completely re-defined our ancient religion based on your New Testament? Please - do so. Jesus was of the House of David. Jesus is the ONE. The ONE. Along with the Father and the Holy Spirit, the Triune ONE of a possible number. SHEMA is revised, partially, in all the Holiness of the Lords. All that was is new. The LORD sort of messed up on the First commandment but he got it right: Yeshuah! Kasich! Yahweh! To be fair, YOU are right and the old sinners are wrong. Bless you! Good luck in Heaven, sorry we’ll all burn.
