I am the living bread which came down from heaven: if any man eat of this bread, he shall live forever: and the bread that I will give is my flesh, which I will give for the life of the world.
All Commentaries on John 6:51 Go To John 6
George Leo Haydock
AD 1849
Christ now no longer calls the belief in him, or the preaching of the gospel, the bread that he will give them; but he declares that it is his own flesh, and that flesh which shall be given for the life of the world. (Calmet)
This bread Christ then gave, when he gave the mystery of his body and blood to his disciples. (Ven. Bede)
