First Holy Communion

Whereupon Jesus said to them, Believe me when I tell you this; you can have no life in yourselves, unless you eat the flesh of the Son of Man, and drink his blood. The man who eats my flesh and drinks my blood enjoys eternal life, and I will raise him up at the last day. My flesh is real food, my blood is real drink. He who eats my flesh, and drinks my blood, lives continually in me, and I in him. As I live because of the Father, the living Father who has sent me, so he who eats me will live, in his turn, because of me. Such is the bread which has come down from heaven; it is not as it was with your fathers, who ate manna and died none the less; the man who eats this bread will live eternally.
John 6:54-59
