And this is what the cultists believe:
Adam was to rule this world but when asked to bow down to him Satan refused saying “this newly created being was younger than I” and he would not do it even at the behest of Michael. Satan set out to take Adam’s throne which he managed to do by seducing Adam’s wife Eve but did not touch Adam.
The result was Eve’s first Child Cain would rule over all Adam and Eve’s children but Cain became wrathful when his younger step brother’s offering was accepted but not his. When Abel explained to Cain that his offering wasn’t accepted because his heart wasn’t pure Cain struck him down. Abel knew Cain was eating his sheep because Cain was clothed in their pelts.
Satan and his Angels fell because they didn’t keep their Heavenly Order. They traded their Heavenly abode to take Adam’s throne. They did so through sexual intercourse with woman. They became locked into flesh bodies because of their coveting women. They also created an addition race of Hybrids that were blended with animals (Rh +).
Satan's/Cain's descendants are part Angel, part human and are sometimes called Demons. It is important to them maintain their "pure" bloodline, with Eve's Rh- blood. They sometimes call themselves sons of Cain. For example, John McCain means John "son of" Cain.
