"I am the living bread that came down from heaven"

We didn't make that one up.  We also didn't give the emphatic insistence that follows:

"Amen, amen, I say to you,
unless you eat the flesh of the Son of Man and drink his blood,
you do not have life within you. 
Whoever eats my flesh and drinks my blood
has eternal life,
and I will raise him on the last day. 
For my flesh is true food,
and my blood is true drink. 
Whoever eats my flesh and drinks my blood
remains in me and I in him. 
Just as the living Father sent me
and I have life because of the Father,
so also the one who feeds on me
will have life because of me. 
This is the bread that came down from heaven. 
Unlike your ancestors who ate and still died,
whoever eats this bread will live forever." (John 6: 51-58)


That would be GOD himself.  If you believe that the Bible gives us the Word of God, bless him and thank him for his most generous gift to us on earth:  the Sacrament of his most holy Body and Blood.
