Just because you are in a covenant with God, this doesn’t necessarily make you God’s “chosen” people.
I say this as a Jew. In the earliest expressions of our people, in ancient times, it was common for us (like our ancient national neighbors around us) to claim that we were unique, and that our God had given us a special status in the world and the universe. We claimed back then that we were chosen above all others in a way that no other people or nation had been chosen, and we asserted in those ancient days that it was by a special revelation (a covenant) from God that made this status so.
But guess what? This is basically what every other nation that coexisted with ours did too. Read and study their religious literature that was written around the same time ours was. Theirs says about the same thing–sometimes the very same thing.
Now, I don’t reject my God, my religion, my culture’s distinctiveness, or the Mosaic Covenant. I’m Torah observant. But being in the Covenant, and being “God’s Chosen People,” well–are they really the same thing?
Besides, according to the Roman Catholic Church in the recent document released by the Vatican in 2015 entitled The Gifts and Calling of God are Irrevocable, regardless of the fact that the Church sees itself in the New Covenant with Jesus, it does NOT teach that the Covenant between God and the Jews has ended, nor that God’s relationship with the Jews changed in anyway: “The covenant that God has offered Israel is irrevocable. ‘God is not man, that he should lie’ (Num 23:19; cf. 2 Tim 2:13). The permanent elective fidelity of God expressed in earlier covenants is never repudiated…God has never revoked his covenant with his people Israel.”
While the Jewish people retain a vocation that emerges authentically out of our own Jewish history, we have no superiority from our calling. We are no more “chosen” or special than any other people because of it. As the Catholic Church teaches, God has not set aside or rejected the Jews because of the New Covenant, neither are there any peoples on earth that are more chosen or more special than any others today either. All today are called by God to love their neighbor and serve one another. All are called to work toward bringing forth God’s redemption.
Instead of seeking to feel especially chosen by God, choose to make your neighbor feel especially chosen by you as you loving seek them out and serve their needs. Worry not how God views the Jews or Christians. Worry more how you are viewed by God and how you are treating your neighbor.
