Charles Spurgeon Commentary John 6:53-56

"Jesus therefore said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man and drink his blood, ye have not life in yourselves. He that eateth my flesh and drinketh my blood hath eternal life: and I will raise him up at the last day. 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." — John 6:53-56 (ASV)

Then Jesus said unto them, verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day. 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.

Let none of you interpret this teaching of Christ as the Jews did, in a carnal manner, and imagine that we literally eat the flesh and drink the blood of Christ when we come to the communion table. The Lord's Supper was not instituted at the time that our Savior spoke these words, and he was speaking of an entirely different matter, the spiritual reception of Christ, the real and true feeding by faith with our spirit upon the Lord Jesus Christ.
