Christian Identity (Wikipedia)

Christian Identity (also known as Identity Christianity) is an interpretation of Christianity which advocates the belief that only Celtic and Germanic peoples, such as the Anglo-Saxon, Nordic nations, or the Aryan race and kindred peoples, are the descendants of the ancient Israelites and are therefore God's "chosen people". 

It is a racial interpretation of Christianity and is not an organized religion, nor is it affiliated with specific Christian denominations...Today it is practiced by independent individuals, independent congregations, and some prison gangs...
