John 6:51-55

New Revised Standard Version Catholic Edition

⁵¹ I am the living bread that came down from heaven. Whoever eats of this bread will live forever; and the bread that I will give for the life of the world is my flesh.”

⁵² The Jews then disputed among themselves, saying, “How can this man give us his flesh to eat?” ⁵³ So 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. ⁵⁴ Those who eat my flesh and drink my blood have eternal life, and I will raise them up on the last day; ⁵⁵ for my flesh is true food and my blood is true drink.
