John 6:53-55

⁵³The Jews therefore strove among themselves, saying: How can this man give us his flesh to eat?

⁵⁴Then Jesus said to them: Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you.

⁵⁵He that eateth my flesh, and drinketh my blood, hath everlasting life: and I will raise him up in the last day.
