The primary role of the Holy Grail in Christian mythology is the cup used by Jesus to inaugurate the communion celebration during the Last Supper. Other stories say that the Holy Grail was a cup used by Joseph of Arimathea to catch Jesus' blood when he was pierced by a spear during the crucifixion. Often, it's the same cup in both situations. For centuries, Christians have written stories about what might have happened to this cup, believed to have miraculous powers.
Is it possible that the blood of Jesus could have been used for a demonic ceremony by those who had Jesus killed?
I have found references to a Vermilion Brotherhood as well as traditions of the Gauls who drank the blood of those they conquered, often beheading them and drinking blood from the head.
Is it possible that this memorial ceremony used in churches could actually be based on an evil ritual ceremony?
Jesus knew the Levitical laws prohibited the drinking of blood. Why would he have made such a remark as "this wine is my blood, drink it"?
Could this story of the "Last supper" have been contrived as 'damage control', written at a later date to appease the christians from uprising, and unbeknownst to them, include them into an evil ritual ceremony?
