It's extremely simple....
........just like all of the different catholic churches,.....it's a question of which one is 'true' ....reigning/empire.....Israel!
All of these 'christian churches' claimed to have replaced national Israel as god's accepted/chosen people.
These churches claim to be the 'New' (reigning/spiritual) Israel.
(It's known as 'Re-placement' theology!)
That is not true. While some Churches believe that, certainly not all do. Unless you were referring to one specific denomination spoken of in post #18 and didn't make that clear.
