John 6:51-53

New Revised Standard Version, Anglicised Catholic Edition

⁵¹ I am the living bread that came down from heaven. Whoever eats of this bread will live for ever; 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.
