John 6:54-57

New Revised Standard Version Catholic Edition

⁵⁴ Those who eat my flesh and drink my blood have eternal life, and I will raise them up on the last day; ⁵⁵ for my flesh is true food and my blood is true drink. ⁵⁶ Those who eat my flesh and drink my blood abide in me, and I in them. ⁵⁷ Just as the living Father sent me, and I live because of the Father, so whoever eats me will live because of me.
