I think the Church in the West has to a large extent become supersessionist in their beliefs. It's common today for many to believe that the Christian Church has superseded the Jews and the nation of Israel, assuming their role as God's covenanted people. I think this happens when some difficult or obscure passages in the New Testament are taken out of context to build narratives against Israel because they were a hard-hearted people that rejected their Messiah. This happens despite many clear New Testament passages that state that God is not done with His people Israel.

I ask then, did God reject His people? Certainly not! I am an Israelite myself, a descendant of Abraham, from the tribe of Benjamin. God did not reject His people, whom He foreknew...

I ask then, did they stumble so as to fall beyond recovery? Certainly not! However, because of their trespass, salvation has come to the Gentiles to make Israel jealous...

I do not want you to be ignorant of this mystery, brothers, so that you will not be conceited: A hardening in part has come to Israel, until the full number of the Gentiles has come in. And so all Israel will be saved, as it is written:

“The Deliverer will come from Zion;
     He will remove godlessness from Jacob.
And this is My covenant with them
     when I take away their sins.”

Regarding the gospel, they are enemies on your account; but regarding election, they are loved on account of the patriarchs. For God’s gifts and His call are irrevocable.

Rom 11

It's helpful to remember that the Bible of the early Church was what we call the Old Testament. The New Testament Canon did not form completely until about the 4th century.

 "the writers of the books that now comprise the New Testament did not intend for their writings to replace or rival the Old Testament. The Christian scriptures were originally intended to be utilitarian documents, responding to specific needs of the early church. It was only with the passage of more than a hundred years after Jesus’s death that Christians began to use the term “New Testament” to refer to the documents that the fledgling church was beginning to view as a single sacred unit. Early Christians viewed the New Testament as the fulfillment of promises made in the Old Testament, rather than as the replacement of the Jewish scriptures."

The Biblical Canon

I believe the practice of handing out Half-Bibles (New Testament only) tends to encourage a replacement theology - not only of the "chosen people" but also of the Old Testament writings.

It was common for the 1st century Church to quote heavily from the Bible of their day. Some of the clearest statements about the kingdom of God are stated in the Old Testament prophets - like Zechariah. 

Rejoice greatly, O Daughter of Zion!
     Shout in triumph, O Daughter of Jerusalem!
See, your King comes to you,
     righteous and victorious,
humble and riding on a donkey,
     on a colt, the foal of a donkey.
And I will cut off the chariot from Ephraim
     and the horse from Jerusalem,
     and the bow of war will be broken.
Then He will proclaim peace to the nations.
     His dominion will extend from sea to sea,
and from the Euphrates
     to the ends of the earth.
As for you,
     because of the blood of My covenant,
I will release your prisoners
     from the waterless pit.
Return to your stronghold,
     O prisoners of hope;
even today I declare
     that I will restore to you double.

Zech 9:9-12

All four gospel accounts either reference or quote directly from Zechariah. It's hard to pick and choose which verses to quote from because there are so many that describe the events leading up to the final restoration and beyond. This restoration is intrinsically connected to His covenant people. And as wild olive branches (Gentiles), we too are also connected by virtue of us being grafted in to that same "root". But this should not be an opportunity to boast.

Now if some branches have been broken off, and you, a wild olive shoot, have been grafted in among the others to share in the nourishment of the olive root, do not boast over those branches.

Rom 11:17-18

I encourage a careful and slow read of this book.
