6:55 my blood is drink. It should be obvious here that Christ is speaking of the symbolic food and drink represented by His flesh and blood; it would be cannibalistic, even if it were physically possible, to actually eat and drink His physical flesh and blood. He made this clear in John 6:63, when He explained: “The words that I speak unto you, they are spirit, and they are life.” This spiritual concept was later to be incorporated in the institution of the Lord’s supper (I Corinthians 11:23-26).
