One of the tactics used by some anti-Christian Zionists is to say that most modern Jews are not true descendants of Abraham, Isaac, and Jacob. This errant theory is based upon wrong conclusions that they have drawn from the history of a medieval nation in which some converted to Judaism. Khazaria was a nation composed largely of Turkish stock that lived between the Black and Caspian Seas during the seventh to tenth centuries.1 Some holding to replacement theology and many neo-Nazis are attracted to this theory in which they conclude that the Jews are not really Jews.
