Independently practiced by individuals, independent congregations, and some prison gangs, it is not an organized religion, nor is it affiliated with specific Christian denominations. Its theology is a racial interpretation of Christianity. Christian Identity beliefs were primarily developed and promoted by authors who regarded Europeans as the "chosen people" and Jews as the cursed offspring of Cain, the "serpent hybrid" or serpent seed (a belief which is known as the two-seedline doctrine). White supremacist sects and gangs later adopted many of these teachings.
