[Angelino97]

Paul was simply saying the Church is open to everyone. That the Jews who rejected Christ (broken branches, no longer on the vine) can still change their minds and accept Christ (be re-grafted onto the vine).

All the promises to the Jews were fulfilled in Christ. There are no other promises. The modern state of Israel is not part of any divine promise to anyone.

Paul was saying that the tree was Jewish, and you know it.
