In his concise and worthwhile book, Unmmasking Freemasonry, Selwyn Stevens, the leader of Jubilee Resources, writes: "Luciferians believe God has a dual nature. They claim he is the god of Lucifer, and the bad god Adonai, both equal in power yet opposite in intent. This is sometimes represented by the circular Yin-Yang symbol of the Taoists and Buddhists, or the black and white checkerboad pattern with the tesselated boarders found in Masonic buildings. Lucifer is sometimes further divided into Isis (the female) principle, and Osiris (the male principal)." (Selwyn Stevens, "Unmasking Freemasonry, page 31)
