I hear you. I had the great fortune of having a Jew whose first language happened to be Hebrew, explain and teach me the Old Testament. From there I searched out rabbinical scholars whose only focus was Judaism, like Christianity did not exist. Next came Catholic commentaries that include the Jewish perspective on all passages that reference Old Testament prophecies. We agree on so much, but there is an impassable stumbling block between the two faith. Christians are convinced Jesus is the Word of God, made flesh, sent into the world for a specific purpose. Jews are convinced God never would have done any such thing. A tenuous connection is both faiths adamantly believe in the Word of God. Therefore, there is no need to call Jesus an idol--and crushingly and needlessly cruel to Christians because Christians see this as a very grave insult to God and God's Words. We love God and as known to all, attacking a loved one also wounds those who love the attacked.
My friend, in presenting the Jewish perspective, was in no way trying to take me away from my own faith. He was sharing Jewish traditions and histories--and their meanings to the Jewish people, a people set apart. Christianity became grafted into, not so much Jewish history, but the history of God and His plans in and for this world. Matthew's gospel (one that causes Jews to be perturbed) was not meant to perturb anyone. Matthew used a literary technique known as foreshadowing, to present God's continuing work/plans for the world. When we remember foreshadowing is never an exact duplicate, but points to a separate similar event, a better, calmer understanding might be reached between Jews and Christians.
Let's take Isaiah 9:6 (For us a child is born)...Isaiah, without a doubt, was referencing King Hezekiah. This reality should be seen by all Christians. It does not in the least affect their part of the story. Christians should see this truly great event in Jewish history as a foreshadowing of a much later history, the birth of Christ. Christians should also be aware that Jews do not, cannot, see the birth of King Hezekiah as a foreshadowing of Jesus, but Jews should be able to understand that gentile Christians do, and their faith in God's work is unshakeable--and Jewish attack on this is seen as wounds directed toward both God and Christians. When we can both understand how vital our faiths are to each other, we should be able to teach without the slightest effort to convert or change anyone's mind. Christians should be able to see Jews are as unshakeable in faith as Christians. Christians should give Jews great respect and take great care not to hurt, as an attack on them, wounds God.
Anyway...sorry for the screed, but perhaps at least, the future, try not to wound Christians on Christmas, just as Christians need to take much greater care on Passover.
