I’m not sure about this pair, but I can tell you there are Messianic Jews who are also ethnic Jews in Israel and others from Orthodox communist Ira are told to stay away from them. They are sneered and hated for their faith and desire to worship the Messiah and retain the focus of Judaism as Yeshua practiced it.
They’re just a throwback to 1st century Christianity. The early Christians considered themselves Jewish, too. They were kicked of the synagogues and told they were no longer welcome there. Hasn’t changed in 2000 years. A Jew that accepts Jesus is no longer practicing Judaism, no matter how much they argue otherwise.
