Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day.
This is about as gruesome as it gets. Vampires and cannibals. The Jews drained the blood from their meat so this saying is doubly offensive. Blood does not have the connotation of life, but of death. The implication is that we must participate fully in the death and resurrection of Jesus. We are not simply giving assent or going along with the whole thing. This is a message that rams home. Do we truly believe? Are we completely trusting in Jesus? Has all other hope been dismissed?
