The Cup of Christ
Most people believe the Holy Grail is the cup used at the Last Supper. Sophie initially thinks this. The novel challenges this conventional view.

The True Meaning

The Secret Revealed
Mary Magdalene
Teabing explains that the Holy Grail is Mary Magdalene, who carried Jesus's child. The word "Sangreal" means "royal blood." The Grail is the womb of Mary Magdalene.
The Bloodline
Jesus and Mary Magdalene had a daughter, Sarah. The Merovingian bloodline descends from them. The Grail is not a thing but a lineage. This redefinition is the core of the novel's theme.
