Charles Spurgeon Commentary John 6:55-60

"For my flesh is meat indeed, and my blood is drink indeed. He that eateth my flesh and drinketh my blood abideth in me, and I in him. As the living Father sent me, and I live because of the Father; so he that eateth me, he also shall live because of me. This is the bread which came down out of heaven: not as the fathers ate, and died; he that eateth this bread shall live for ever. These things said he in the synagogue, as he taught in Capernaum. Many therefore of his disciples, when the heard [this], said, This is a hard saying; who can hear it?" — John 6:55-60 (ASV)

For my flesh is meat indeed, and my blood is drink indeed.

He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him. As the living Father hath sent me, and I live by the Father, so he that eateth me, even he shall live by me. This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live forever. These things said he in the synagogue, as he taught in Capernaum. Many therefore of his disciples, when they had heard this, said, This is an hard saying; who can hear it?

And a hard saying it really is until we are instructed by the Spirit of God to understand it. The Papist has made it into a gross and carnal saying, teaching people that they really, and actually, and corporeally, eat the flesh and drink the blood of Christ, which is horrible blasphemy, and nothing less. But those who are taught by God see the inward meaning of the truth peeping up from behind the letter, and know what it is to receive into their hearts—though not into their bodies—and into their thoughts—though not into their mouths—the very body and blood of Christ.
