A Contract with G-d

Question/statement :
1. How do we know someone is a Jewish soul, even though they were taught other religions?

We have no idea until the High Priest wears the Urim &Turin and can tell us which tribe we are apart of.
I have read in different places and watched on YouTube that no one knows. Even a Jewish person does not know. (Unless a Kohen/Cohen or Levite.).
We are not allowed to use DNA,because the Rabbis, are more concerned about a person who was raised as Jewish, may not be Jewish. Or the Kohen DNA test, where one may not have the Kohen DNA.

It *seems* that a Jewish soul, will love a Jewish person.

So, do we then say, this will repeat once the Moshiach is revealed by Elijah?

Just curious! Reply
