Jesus the Jew and Christianity

Almost immediately after the life and itinerant preaching of Jesus of Nazareth, his message was lost and perverted. What we call Christianity was from day one anti-semitic and supersessionist. Two thousand years of documented hatred and persecution of Jews can and must be laid at the feet of Christians.
And if you know how and are willing to be honest with the text and yourself, you will see that this hatred and claim to surpass its background in Judaism is in the New Testament. It is there in the earliest document, I Thessalonians, when Paul already redefines the messiah (Jewish) as the Christ (Greek) and talks about his coming back. The thought NEVER crossed Jesus' mind. It is there in Galatians when Paul demonstrates his misunderstanding of the Law and redefines Israel and children of Abraham by faith (his exegesis of Genesis 15 and 17) rather than circumcision and history. Because he can not possibly say that God breaks His promise made to Israel, Paul has to give some interesting mental and theological gymnastics in Romans where he lays out the terms of engagement between the weak and the strong and where he says Israel must be brought (saved) into the fold before the End. To his last letter (Romans) Paul continues to impose his redefinition of the Christ and parousia.
In Constantine's Sword, James Carroll has masterfully documented the sad and horrific history of Christianity's abuse of Judaism. From Paul and the New (think of the implications of that word!) Testament, to Constantine and the sign of the cross and his mother's "finding" the True Cross and the seamless robe, to Augustine's argument that Jews must be "protected" until the End, to Ambrose's argument to kill Jews, to the Blood Libel originating in England, to Acquinas' rational argument for the persecution of Jews, to Luther's The Jews and Their Lies and his argument to kill Jews who will not convert, to Hitler's identification of himself as the messiah, to the Holocaust, to John Paul II and Benedict XVI and their emphatic supersessionism and "one way" to salvation.
The message of Jesus of Nazareth is a challenge to the world today. Unfortunately Christianity has almost drowned it out.
