Sounds like Arnold had the same issues in his day with his Jewish father as we have today here in this forum:He found it challenging to remain Jewish and believe in Yeshua too. His own father rejected him for being a Jewish Christian. Which btw has been the standard definition for centuries for Jews who remain Jewish but place faith in Yeshua. .

True...
Technically, whenever I see Jewish disciples (or Gentiles ) saying of Jewish believers in Christ "You're not Jewish - you're just a Christian!!!" - or even trying the "Well that's just Christian" card on them the moment it comes to theological stances while saying of themselves they're the ones truly "Messianic Jewish" in lifestyle, IMHO, it is nothing more than evidence that they really don't know what it means to be "Christian" (or Messianic) to begin with as the movement intended ...as to be Messianic doesn't equate to not being Christian in thinking (false scenario) - and Biblically/historically, Jewish believers in Messiah - whether in Jerusalem or in the Diaspora - had NO problem identifying as Christian since the Way/Nazarene Sect within Judaism was also known as that (

Acts 11:25-27 Acts 26:27-29 - more shared in #

Other non-believing Jews have long noted this - and thus, it's not even an issue worth debating long term..
There are so many amazing Jewish believers in history - identifying as Christian - and they never let their fathers, mothers or family tell them that they were not Jewish in lifestyle since they knew that the most Jewish thing one could do was trust in Yeshua the Messiah - and seek to serve/live for HIM as a disciple of the Lord. Consequently, it didn't matter whether they had to contend with family members who stereotyped all Christians in the negative because of what other Christians did historically to Jewish people in ideology/practice - nor did it matter when other Gentiles (bitter toward the Church or seeing errors commonly taught in many Christian circles) chose to REACT to them by claiming broad-brushes/wide sweeping generalizations (i.e. "Christianity is just anti-Semitic at its core", "All Christians don't value Israel or Torah", "Christianity is Gentile focused and will never allow one to truly honor Yeshua!!!", etc.) - things that Jewish Christians never held to - be it in our time or in the early body of Christ. They were who they were - they loved God's Law and the Work of the Messiah...and they went with that.
As it concerns the OP, there've been several good threads on the issue which I thought were good for reference (some which can be found if choosing to go here to #

But as it concerns the issue of Jews often disowning family members who are believers/identifying as Christians, it should be noted that it simply goes back to the central battle of witnessing for the Messiah. As said before elsewhere, with many Jewish families, the NT as you know bids Christians to provoke the Jews to religious jealousy. If interested, one of the Jewish believers I've kept up with did a rather interesting piece on what jealousy could be...and how it's possibly misunderstood..
For more, here's the article by one who's an Eastern Catholic Jew (and who has worked with Messianic fellowships).....and to see what she said, one can go online/look it up under the following:
For the amount of Jewish people who are coming to Christ in droves from all kinds of backgrounds---be it in the U.S or Israel and other places globally--- it is interesting to see the developments.
What provoked/MADE them jealous was seeing the simple LOVE and POWER TO BE Delivered from bondages that made them realize how real Christ was. In example, when you're dealing with Crack-Cocaine addictions or caught in prostitution, it doesn't matter to many whether you're "Messianic" or not since they're looking to know whether or not someone truly loves them and can give them hope. To see the kind of love that Yeshua showed others who were often deemed untouchable by others in the Jewish religious leadership (Luke 14, Luke 15, Matthew 8, John 8, etc), it was his radical mindset toward interaction that got their attention.....and for many Jews who are agnostic, they're actually tired of much of the debates about what is or isn't "Jewish." They grew up in many differing camps of Judaism---and many times, though their parents/community were serious about what they believed, it simply wasn't something that they felt fulfillment in....till they came to fall in love with the Grace/Truth revealed in Christ (John 1).
The Gospel is what must be central....but, many Messianics don't even preach the Gospel. Rather, they're happy just "keeping" the Torah and "getting back to their roots" - and yet never being consistent in preaching Christ. One of the ladies in my fellowship who's Jewish had this experience with her mother - who sworn growing up she could never be a Christian since she was Jewish (and in her mind, to be Christian - as she had seen it growing up - meant that you had to reject being Jewish) - and on her deathbed, she had prayed/asked the Lord to reveal Himself to her....and she died in peace accepting that Christ was the Messiah. Amazing to see what went down - and that at the end of the day, it wasn't discussion on Torah alone that won her heart - or discussion on Jewish customs.
It was studying who the man known as Yeshua was all about - and that is what she needed to truly be Jewish as the Lord always intended.
Can you imagine what would've happened if the centrality of the Gospel was not kept central for many Jews who came to faith? The Body would be diminished - you'd not hear of others, for example, like the author of "Tortured for Christ" Rev.

I'm truly taken about by how many Jews noted that what brought them to YESHUA was seeing the love and compassion shown to them by believers. One Messianic Jew noted how he was challenged to dare trusting in Yeshua even though he used to say he didn't need that - as something simply wouldn't let him have peace in thinking only Gentiles needed to have Yeshua or that Gentiles were "crazy" for trusting in Christ.
For another example, I'm reminded of Rabbi Baruch Rubin - president of Messianic Jewish Communications and Rabbi of Emmanuel Messianic Jewish Congregation , both of Clarksville, Maryland. His story stands out to me when seeing what it was that impacted him to trusting Yeshua ..
and in his words (for brief excerpt):
One day, I had had enough. I went up to Loren (a tall Swede) and said, "What is it about you that makes you so blankety-blank' happy." (My speech was rather salty in those days.) Without blinking an eye, he said, "Your Messiah lives in my heart."
"What," I challenged, "is my Messiah doing living in your heart? And who is my Messiah, by the way, and what's he doing in your heart, anyway?" It was then that I learned the secret of Loren's peace. He told me that Jesus was my Messiah and that He lived in his heart (an expression that really sounded strange, especially when I thought about it literally). But he told me that Jesus was a Jew who came to the Jewish people to bring them back to God, and that he could do the same for me. None of it made any sense to me, but I was provoked to jealousy and later became a follower of the Messiah, too. How can you provoke your Jewish neighbor to jealousy? With your life, your love and your language. Loren's life reflected a calm that I hadn't seen anywhere around me. His love for me was sincere and I felt it. And his language was sensitive. He was willing to talk "my" language. If he had said he "knew Jesus Christ as his personal Lord and Savior," I would have said, "Well, that's good for you. You're a Christian. That's what you're supposed to do." But he stepped into my world by speaking about my Messiah. He used language that would get my attention and provoke me to jealousy.
Powerful!!!
