The entrance of Your Word, O LORD, bringeth light. The New Testament as written is not anti-Semitic. However, much Christian theology has been and is anti-Semitic and I believe the culprit is theology. Theology is what man thinks of God and that frankly isn't the issue. If Jesus Christ were to come into this world today in the flesh, the same as He did previously, He would again be crucified by this wicked world because His righteousness would inflame them to hatred and jealousy.
Most theologians allege that the Abrahamic covenant is no longer relevant.
It is true they were under chastisement by God for centuries, and when you are standing on the seashore there is no way you can stop that tide from going out. But when the time comes, and that tide reverses, you can't stop it from coming in either. The nations of this world, and through the United Nations and through other power blocks, constantly malign Israel and speak of her having no right to be there, but they will not stop what God is doing. He will keep His covenant and many more of them will be soon coming home. Oragon, St. Augustine and many others.
