When Christians distance themselves from their Hebrew roots it’s like cutting the branch off that they stand on.
The entire Bible is built on Hebrew themes and context. The New Testament, while written primarily in Greek, is an explanation of so many of the things that the Old Testament laid the foundation for. God used the Hebrew people as a means of revealing His character to the nations. God instituted His feasts, first among the nation of Israel, as a way to teach His redemptive plan seven times a year. Yeshua (Jesus) is our Hebrew savior. He taught using the Hebrew text and customs for illustrations. He was given titles understood best in the Hebrew context (Lamb of God, Messiah, the Word, Son of Man, etc…). He used people of Israel, His disciples, to take His message to the world and seek and save the lost.
Romans chapter 11 makes it pretty clear that non-Jewish believers (gentiles) were grafted into the tree of faith that God had been growing through the nation of Israel. We didn’t become an entirely new tree. We entered into a covenant relationship that existed for over a thousand years before the first “Christian” church ever met. Jesus came to bond the nations through His sacrifice.
Therefore remember that at one time you Gentiles in the flesh, called “the uncircumcision” by what is called the circumcision, which is made in the flesh by hands— remember that you were at that time separated from Christ, alienated from the commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world. But now in Christ Jesus you who once were far off have been brought near by the blood of Christ.
Ephesians 2:11-13 (ESV)
We have been adopted into a family of faith, that is rich, and so beautiful. To know our Hebrew roots unlocks so much of the magic in the Bible. To disregard the importance of our spiritual ancestry is to walk blindly towards key elements of our faith. That single page that divides the Old and New Testament is a relic and a unhelpful distraction from reality. The Bible is one unified story from beginning to end. To live exclusively in Matthew to Revelation is like only knowing half the story. Same goes for those who stick so tightly to the Torah and rarely venture to the teachings of Jesus and His apostles. God gave us seven beautiful feasts to learn from and celebrate year around. He gave a law that reveals so much about who He is and what holiness looks like. And He spoke hundreds of prophecies about our Savior, His plan for our lives, and the course of the world. The story of Israel is the story of us. We can see life experiences through theirs. It’s time for that page that divides our Bibles to be torn out, physically, mentally, and emotionally. Because Jesus tore it out spiritually.
…for in Christ Jesus you are all sons of God, through faith. For as many of you as were baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus. And if you are Christ’s, then you are Abraham’s offspring, heirs according to promise.
Galatians 3:26-29 (ESV)
