Another question about DNA
My country has the highest concentration of Bnei-Anussim in the world. Recently (in recent decades) there has been an "explosion" of people discovering themselves as "Jews," or descendants of Jews, because of a law in Portugal that guaranteed citizenship to the descendants of Jews who suffered from the inquisition. Due to worldly interests, genealogy has developed a lot in the country and many people have discovered its true origin.
Brazilian synagogues define a Bnei-Anussim as a Jew when he decides to assume this identity and do the process of Teshuvah. It is almost like a traditional Jewish conversion, but the court is not necessary because you, being Bnei-Anussim, are automatically part of the alliance, leaving only to decide whether you want to assume this identity or not.
The movement has been growing a lot and one thing makes me curious: many people, including myself, see in themselves Jewish traits of all kinds and, after discovering their genealogical heritage, come to associate this trait with the fact of being Jewish. I am trying to understand what this is just confirmation bias and what is *really* a Jewish trait.
One question that non-Messianic Jews ask is this: why is no one attracted to the ethnic heritage of isolated indigenous tribes, but many people "feel Jewish"? What, exactly, is the Jewish ethnicity special about? It is important to think about this because many of the Bnei-Anussim no longer have Jewish DNA. In fact, we do not see descendants of Germans feeling "German," or descendants of Italians fighting over pizza sauce, or descendants of Russians with high tolerance for vodka, or descendants of indigenous people walking around half naked.
A convincing answer to this question is that the Jewish people are the only ones who have a covenant with God, but it is not enough. Is there any text in the Bible that states that the Israelites and their descendants would have this special calling?
When I found out that I am a Jew, I started adopting the Jewish diet and learning various Israeli recipes. I realized that no other food makes me as full as this one. This is not a confirmation bias because I did a DNA test that proved to be a great affinity with the Arab/Mediterranean diet.
What do you think of all this?
