I am ethnically Jewish, yes. I believe in (Yeshua), the anointed one and son of God, who is my Lord and Savior.
Ethnicity means absolutely nothing, as Paul makes very clear in Romans 2:28-29: “A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a person’s praise is not from other people, but from God.”
This explains the texts in the Book of Revelation regarding the issues in Smyrna and Philadelphia, particularly the fact that the ethnic Jews persecuting believers were referred to as the Synagogue of Satan. They persecuted believers, slandered them, and turned them over to the Roman authorities. The fact that they were ethnically Jewish didn't matter; they were Jews in the flesh but not inwardly.
The individuals in power you mentioned, who are disproportionately Jewish, are often from very few families that haven't practiced Judaism for more than three generations. According to Jewish tradition, they are no longer considered Jewish. For example, the Rothschilds continue to identify as Jewish despite having more than three generations without practicing Judaism. More than 90% of those labeled as Reform Jews are not even considered Jewish under stricter interpretations of the tradition.
If we are to adhere to Jewish tradition, those who call themselves Jews and are in positions of power are often not considered Jewish because the vast majority of them come from families that have not practiced Judaism for over three generations.
