Some say that Israel is now Babylon, due to the talmud having been compiled there. I don't believe that. But as a Catholic I do believe that the Catholic Church is the new Israel, the Israel of the New Covenant. If one believes in the divinity of Jesus Christ, it isn't a "usurpation" but a simple fulfilment of the law, the old made new. The Temple veil was torn when Jesus died for a reason, after all.
Would it do any good to point out that these are all beliefs and that they are not self-evidently true? By insisting on reading the Hebrew Bible through the lens of the "new testament" all chrstians are guilty of the logical fallacy of "affirmation of the consequent."
Fundamentalist Protestants, whose only "chrstendom" is Biblical Israel and for whom historical chrstianity is "the great apostasy," have a very different position from yours.
Paul sure seemed to feel a different way, didn't he?
You will say then, “Branches were broken off that I might be grafted in.” [...] For if you were cut out of the olive tree which is wild by nature, and were grafted contrary to nature into a cultivated olive tree, how much more will these, who are natural branches, be grafted into their own olive tree? (Ro 11:19,24)
