- "You see, before he sacrificed himself for our sins, our Lord gave a final gift to humanity He fathered a child. For generations, The Grail has protected this holy lineage in preparation for one event: The end of the world."
- —Saltonstall to Klaus Starr[src]
The Grail is a clandestine organization with holdings and agents from 113 countries under the guise of Grail Industries. The Grail is tasked to protect the bloodline of Christ. For over two millennia, the Grail works hand-in-glove with Heaven while having contacts with Hell.
Their ultimate goal is to facilitate the apocalypse through nuclear warfare to pave way for Humperdoo to take over as the messiah.
Throughout the years, the Samson Unit terminated false prophets that served as threats to Christs' throne, including assassinating Abraham Lincoln.
