John 6:52-59 (New International Version)

 ⁵²Then the Jews began to argue sharply among themselves, "How can this man give us his flesh to eat?"

 ⁵³Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. ⁵⁴Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. ⁵⁵For my flesh is real food and my blood is real drink. ⁵⁶Whoever eats my flesh and drinks my blood remains in me, and I in him. ⁵⁷Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. ⁵⁸This is the bread that came down from heaven. Your forefathers ate manna and died, but he who feeds on this bread will live forever." ⁵⁹He said this while teaching in the synagogue in Capernaum.
