John 6:52-54

⁵²The Jews therefore contended with one another, saying, “How can this man give us his flesh to eat?”

⁵³Jesus therefore said to them, “Most certainly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you don’t have life in yourselves.

⁵⁴He who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day.
