John 6:54-57

Revised Standard Version Catholic Edition

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. ⁵⁶ He who eats my flesh and drinks my blood abides in me, and I in him. ⁵⁷ As the living Father sent me, and I live because of the Father, so he who eats me will live because of me.
