Nope, it was because he could take part in the slave trade, Christians were taken to be sold as slaves to the Muslims. This wasn’t allowed as a Christian but is as a Jew.

Understand that Jews infiltrated the elites of Khazaria, much like Esther and her comrades infiltrated the Persian elites. At a certain point, the Jewish elites of Khazaria forced the non-Jewish commoners to convert and Khazaria became a ‘Jewish’ state. Don’t believe the nonsense about the Khazarian king choosing Judaism on its merits. That’s not how things work. The King of Khazaria chose Judaism because he was already a Jew.

When Khazaria was destroyed, those same Jewish elites fled to Eastern Europe.

But here’s what’s REALLY important.

Jews are Jehovah’s Chosen People. They worship Jehovah. Jesus said the Father of the Jews is Satan (John 8:44). Therefore, Jehovah is Satan.

Europeans are not Jews. Those claiming descent from Israelites are Judaizers, i.e., Satan worshippers. The Bible says “And I know the evil speaking of those saying themselves to be Jews, and they are not, but are a synagogue of Satan.” Rev 2:9, 3:9.

St. John Chrysostom had particularly harsh words for Judaizers.
