In Gnosis, the term race generally refers stages of development in the history of humanity. See: What are the Root Races and Subraces?
In regards to the variations visible in the contemporary humanity, what people call "black, brown, yellow, red, white" Samael Aun Weor wrote:
"God has no preference for anyone. All human beings without distinction of sex, race, creed or color are beloved children of the Father. They have the same rights... God has no racial prejudice. He loves all his children with infinite love, without distinction of sex, race, creed or color. We must love all human beings. We must give even the last drop of our blood for all our brothers and sisters who belong to this great human family." - Samael Aun Weor, Igneous Rose
"The hour has arrived in which we have to comprehend that we are in fact one great family, without distinction of races or nations." Closing Speech at the 1975 Gnostic Congress
