The founder of The Nation of Islam, although never a Bible Student / Jehovah's Witness mentioned both Russell and Rutherford in his writings, claiming they were two of the best white men who ever lived.
He relied on much of Rutherford's interpretations. Substituting Rutherford's Christendom for "whitey".
There is a mutual respect between both groups. I recall several times while street witnessing in Jersey City, NJ in the early mornings, meeting up with members of the Nation offering their literature, They would wave at us, or stop and we would shake hands, they would refer to us as "brothers."
It wasn't until later, when I did some research that I found references to Judge Rutherford, and his apocalyptic writings.
So in essence, Rutherford as racist as he was, may very well have given birth to a black movement.
