Christian Identity movement originated from nineteenth-century British-Israelism. According to the movement, the Anglo-Saxon, Celtic, Germanic, Nordic, and Aryan populations of Europe were the real Lost Tribes of Israel and God’s chosen people. Christian Identity adherents accuse Jews of pretending to be the descendants of the ancient Israelites and consider them as imposters.
There are different theories within the Identity regarding the ancestry of Jews.
One theory of the Identity asserts that Jews descended from an Asian people known as the Khazars. The Khazar Empire was a Jewish state that mainly consisted of Turks. It settled near the Black Sea during the Middle Ages. Hence, Jews were “false” Israelites.
On the other hand, the most extreme “two seedline” theory of the Identity argues that Jews are the children of Satan. According to the theory, the seduction of Eve by the Serpent in Eden was sexual. Their sexual affair produced Cain, who was "a Mongrel, a Hybrid, a Non-Race." Cain's brother Abel was the offspring of Eve with the pure, white Adam. Cain's murder of Abel started the war between the Satanic forces of "Jewry" and the pure white race born of Adam.
An alternative to the "two seedline" theory is the "one seedline" theory. Identity's one-seed believers suggest that Jews descended from Jacob's brother Esau. Esau cursed God and married outside the Israelite race. His actions resulted in God's hatred upon him and his descendants, also called the Jews. One-seed believers argue that Israel's identity belongs solely to the Anglo-Saxon, Celtic, Germanic, Nordic, and Aryan people.
Overall, the Christian Identity movement claims that the true holders of white identity are the Anglo-Saxon, Celtic, Germanic, Nordic, and Aryan people. Jews are not white; they stole Israel's identity.
