John 6:53-55

Revised Standard Version Catholic Edition

⁵³ So Jesus said to them, “Truly, truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you; ⁵⁴ he who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. ⁵⁵ For my flesh is food indeed, and my blood is drink indeed.
