No, you don't "gotchme."
1. Messianic Jews are Christians.
2. No Messianic Jew -- no human being -- has taught Torah "for 3700 years." People don't live that long.
As I made clear, all rabbis were born in the 20th or 21st century. All they know is what they learned in the few decades of their lives, same as any Christian theologian.
Do you "gotch" that? Just because ancient Israelites wrote the Bible doesn't mean that the rabbi down the block has some special insight into it. Knowledge is not passed on in DNA.
Christian theologians are just as capable of studying ancient languages and documents, with the added advantage of studying them through the lens of the New Testament.
If you read the Word of God, you will see that Jesus was called Rabbi or Rabboni multiple times. Not sure where you’re getting your information
