John 6:52-57

⁵²At that the Jews started quarrelling among themselves, saying, “How can this man give us his flesh to eat?!”

⁵³So Jesus said to them: “Most assuredly I say to you, unless you eat the flesh of the Son of the Man and drink His blood, you do not have Life within yourselves.

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

⁵⁵Really, my flesh is genuine food and my blood is genuine drink.

⁵⁶Whoever chews my flesh and drinks my blood abides in me and I in him.

⁵⁷Just as the living Father sent me and I live because of the Father, so also the one who feeds on me will live because of me.
