After leading five trips to Israel, spending time with and having deeply meaningful conversations with Jewish friends, learned teachers, guides, and theologians, I acknowledge that most Christians (myself included) have much to learn regarding Jewish traditions and the Hebrew roots of Christ and Christianity. Each trip to Israel reveals more that I had not previously known or acknowledged. Yet, the joy of these trips and these conversations is that the message of Scripture and the good news that is the Gospel is affirmed more and more, even as I seek to know more.
It is true that during the days of the Byzantines especially and following, there was an effort by Christians and some in the church to erase the Jewishness from Jesus' story and the message of the New Testament. A cursory reading of the New Testament makes that assertion implausible.
The Jewish Jesus
Despite the ignorance and racism that precipitated such teaching, the facts remain - Jesus was Jewish. He spoke Hebrew. He likely spoke Hebrew more than has been acknowledged. He did not come to erase Torah (the law) or the teachings of the prophets but to fulfill them.
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven." Matthew 5:17-20 (ESV)
To discount the Jewishness of Jesus is ignorant at best, sinfully racist at worst.
What is the Hebrew Roots Movement?
Despite the need to acknowledge and understand the Jewish heritage of Christ and the teachings within scripture that begin with the creation of humanity and celebrate the one true God through his covenant relationship with his chosen ones, there is a dangerous theology emerging (actually not new, just a modern version, albeit wrapped in Hebraisms, of gnosticism) categorized as the Hebrew Roots movement.
Here's a good overview of the belief system as taken from gotquestions.org...
Hebrew Roots movement is the belief that the Church has veered far from the true teachings and Hebrew concepts of the Bible. The movement maintains that Christianity has been indoctrinated with the culture and beliefs of Greek and Roman philosophy and that ultimately biblical Christianity, taught in churches today, has been corrupted with a pagan imitation of the New Testament gospels.
Those of the Hebrew Roots belief hold to the teaching that Christ's death on the cross did not end the Mosaic Covenant, but instead renewed it, expanded its message, and wrote it on the hearts of His true followers. They teach that the understanding of the New Testament can only come from a Hebrew perspective and that the teachings of the Apostle Paul are not understood clearly or taught correctly by Christian pastors today. Many affirm the existence of an original Hebrew-language New Testament and, in some cases, denigrate the existing New Testament text written in Greek. This becomes a subtle attack on the reliability of the text of our Bible. If the Greek text is unreliable and has been corrupted, as is charged by some, the Church no longer has a standard of truth.
Benefits of the Hebrew Roots Movement
As with many religious groups that claim their genesis in biblical Christianity, there are beneficial qualities of what many Hebrew Roots teachers proclaim. This is not unlike other groups who promote healthy living and morality, yet hold to biblically unorthodox theology. For Christians, learning details of Jewish life adds insight into many of the biblical stories, especially the parables and teachings of Christ. It is beneficial and good for believers to understand and study the feasts of Israel, the covenant teachings, and other aspects revealed through scripture, and even Jewish celebrations and teachings that are extra-biblical.
A study of Torah can enhance believers understanding of the teachings of Christ. Yet, while good for Gentile Christians to identify with Israel, it is not beneficial to identify as Israel. It is disingenuous at best.
Ultimately, the benefits of the Hebrew Roots movement are few and far between, and outnumbered by the dangers.
Gentile Christians have been grafted into God's chosen people. This is expressed by Paul in his letter to the Romans.
"But if some of the branches were broken off, and you, although a wild olive shoot, were grafted in among the others and now share in the nourishing root of the olive tree, do not be arrogant toward the branches. If you are, remember it is not you who support the root, but the root that supports you. Then you will say, 'Branches were broken off so that I might be grafted in.' That is true. They were broken off because of their unbelief, but you stand fast through faith. So do not become proud, but fear. For if God did not spare the natural branches, neither will he spare you." Romans 11:17-21 (ESV)
It should be noted, however, that the grafting in of Gentile believers is not into the Mosaic Covenant, but "they are grafted into the seed and faith of Abraham, which preceded the Law and Jewish customs. They are fellow citizens with the saints (Ephesians 2:19), but they are not Jews."(gotquestions.org)
The Danger of the Hebrew Roots Movement
Over the past few years, an increase of those who hold to the Hebrew Roots theology has occurred. Some Christians are abandoning traditional biblical orthodoxy and orthopraxy (justified by Hebrew Roots believers since they believe the church corrupted beyond repair.) Seminary students, pastors, and self-taught theologians have joined the movement. The dangers are expressed well here...
The Hebrew Roots movement is dangerous in its implication that keeping the Old Covenant law is walking a "higher path" and is the only way to please God and receive His blessings. Nowhere in the Bible do we find Gentile believers being instructed to follow Levitical laws or Jewish customs; in fact, the opposite is taught. Romans 7:6 says, "But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code." Christ, in keeping perfectly every ordinance of the Mosaic Law, completely fulfilled it. Just as making the final payment on a home fulfills that contract and ends one’s obligation to it, so also Christ has made the final payment and has fulfilled the law, bringing it to an end for us all.
Ultimately, the Hebrew Roots followers, though well intentioned I'm sure, have believed in teachings that are not grounded in scripture, nor affirmed in the teachings of Christ, but sound biblical (as opposed to being biblically sound.) Inerrancy of the Word of God is abandoned by those who believe in a "better way" or who have slid into what is also called Yahwism or the Sacred Name Movement.
Can the Hebrew Roots believers line up alongside evangelical Christianity? Apparently not, by their own admission. At this point, Ephesians 4 and other passages are ignored and forsaken and unity in Christ is abandoned, as division grows and falsehood is propagated. This is grievous.
