Hello sir. I want to start by quoting this verse John 1:14 The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth. Here John said “We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth”. He is the perfect flesh that came from heaven. In the same book John 6:51 Jesus said " I am the living bread that came down from heaven. Whoever eats this bread will live forever. This bread is my flesh, which I will give for the life of the world.” He came to give life to corrupted flesh. His flesh had Divine power to redeem humankind. We do not have any good in our flesh . It’s always against us. Paul said in Galatians 5:17" For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want". He has described the deeds of our flesh in Galatians 5:19-21
Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God. And in Ephesians 2:3
“Among them we too all formerly lived in the lusts of our flesh, indulging the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest”. I want to add William Barclay’s words here
HIS BODY AND HIS BLOOD
These ideas would be quite normal to anyone brought up in ancient sacrifice. The animal was very seldom burned entire. Usually only a token part was burned on the altar, although the whole animal was offered to the god. Part of the flesh was given to the priests as their perquisite; and part to the worshipper to make a feast for himself and his friends within the temple precincts. At that feast the god himself was held to be a guest. More, once the flesh had been offered to the god, it was held that he had entered into it; and therefore when the worshipper ate it he was literally eating the god. When people rose from such a feast they went out, as they believed, literally god-filled. We may think of it as idolatrous worship, we may think of it as a vast delusion; yet the fact remains these people went out quite certain that in them there was now the dynamic vitality of their god. To people used to that kind of experience a section like this presented no difficulties at all.
Let us see now if we can find out something of what Jesus meant and of what John understood from words like this. There are two ways in which we may take this passage.
(i) We may take it in a quite general sense. Jesus spoke about eating his flesh and drinking his blood.
Now the flesh of Jesus was his complete humanity. John in his First Letter lays it down almost passionately: “Every spirit that confesses that Jesus Christ has come in the flesh is of God; and every spirit which does not confess Jesus is not of God.” In fact, the spirit which denies that Jesus is come in the flesh is of antichrist (1 John 4:2-3). John insisted that we must grasp and never let go the full humanity of Jesus, that he was bone of our bone and flesh of our flesh. What does this mean? Jesus, as we have seen again and again, was the mind of God become a person. This means that in Jesus we see God taking human life human problems, battling with our human temptations, working out our human relationships.
Therefore it is as if Jesus said: “Feed your heart, feed your mind, feed your soul on the thought of my manhood. When you are discouraged and in despair, when you are beaten to your knees and disgusted with life and living–remember I took that life of yours and these struggles of yours on me.” Suddenly life and the flesh are clad with glory for they are touched with God. It was and is the great belief of the Greek Orthodox Christology that Jesus deified our flesh by taking it on himself. To eat Christ’s body is to feed on the thought of his manhood until our own manhood is strengthened and cleansed and irradiated by his.
Jesus said we must drink his blood. In Jewish thought the blood stands for the life. It is easy to understand why. As the blood flows from a wound, life ebbs away; and to the Jew, the blood belonged to God. That is why to this day a true Jew will never eat any meat which has not been completely drained of blood. “Only you shall not eat flesh with its life, that is, its blood” (Genesis 9:4). “Only you shall not eat its blood” (Deuteronomy 15:23). Now see what Jesus is saying–“You must drink my blood–you must take my life into the very centre of your being–and that life of mine is the life which belongs to God.” When Jesus said we must drink his blood he meant that we must take his life into the very core of our hearts.
What does that mean? Think of it this way. Here in a bookcase is a book which a man has never read. It may be the glory and the wonder of the tragedies of Shakespeare; but so long as it remains unread upon his bookshelves it is external to him. One day he takes it down and reads it. He is thrilled and fascinated and moved. The story sticks to him; the great lines remain in his memory; now when he wants to, he can take that wonder out from inside himself and remember it and think about it and feed his mind and his heart upon it. Once the book was outside him. Now it is inside him and he can feed upon it. It is that way with any great experience in life. It remains external until we take it within ourselves.
It is so with Jesus. So long as he remains a figure in a book he is external to us; but when he enters into our hearts we can feed upon the life and the strength and the dynamic vitality that he gives to us. Jesus said that we must drink his blood. He is saying: “You must stop thinking of me as a subject for theological debate; you must take me into you, and you must come into me; and then you will have real life.” That is what Jesus meant when he spoke about us abiding in him and himself abiding in us.
When he told us to eat his flesh and drink his blood, he was telling us to feed our hearts and souls and minds on his humanity, and to revitalize our lives with his life until we are filled with the life of God.
(ii) But John meant more than that, and was thinking also of the Lord’s Supper. He was saying: “If you want life, you must come and sit at that table where you eat that broken bread and drink that poured-out wine which somehow, in the grace of God, bring you into contact with the love and the life of Jesus Christ.” But–and here is the sheer wonder of his point of view–John has no account of the Last Supper. He brings in his teaching about it, not in the narrative of the Upper Room, but in the story of a picnic meal on a hillside near Bethsaida Julias by the blue waters of the Sea of Galilee. Thank you. God bless you
