I visited a small Messianic Jewish temple. Many of the ethnically Jewish folks there still dress in the Hasidic manner, especially the women, who stay covered up, including their hair. They observe the holy days of both religions (Passover and Easter, etc), and read from the New Testament after passing the Torah around the congregation and reading from the Hebrew bible. The rabbi dresses traditionally and wears a yarmulke and sidecurls. They give thanks for their Messiah Jeshua (Jesus) having already come!
I attened a Messianic temple when I lived in Albuquerque. And I’m not even Jewish. I was welcomed as a “grafted branch”.
A lot, if not most of “Messianic Jews” are NOT Jews. They are gentiles. That is a cult designed to ensnare uneducated Jewish souls. They put enough Jewish-LIKE stuff in their “services” to fool the unschooled, but they basically make it up as they go along. It is a complete travesty that these charlatans even touch a sefer Torah or utter any Jewish prayers. Their prayerbook is called by the Jewish designation, a siddur, but the resemblance to authenticity ends there. There are numerous references to JC in it and to the New Testament, both of which are completely not a part of authentic Judaism. The “rabbi” to which you refer is a complete fake without authentic Jewish ordination and any “Jewish” clothing they wear is simply part of the entrapment costume. It doesn’t take more than a few phrases to completely blow them out of the water as the fakes that they are. So basically, they are a cult with the express design of convincing Jews who were not fortunate enough to have a Jewish education that theirs is authentic Judaism. Kind of like trying to sell Naugahyde as leather. I make no apologies for tellin’ it like it is. I’ve seen these Messyantics in action and they are truly detestable. Anyone who thinks that deliberate misleading of uneducated Jews for the purpose of conversion is a good idea, go pound sand.
